Since being founded in 2018, Copper has been building the standard for institutional digital asset infrastructure with a focus on custody, collateral management, and prime services. Led by Amar Kuchinad, Copper's Global CEO, the firm provides a comprehensive suite of custody, trading and settlement solutions that reduce counterparty risk and bring greater capital and operational efficiency to digital asset markets. At the heart of Copper's offering is Multi-Party Computation (MPC) technology – the gold standard in secure custody. Copper’s multi-award winning custody system is unique in that it can be connected to centralised exchanges, DeFi applications and even staking pools without the assets leaving the custody. Built on top of this state-of-the-art custody, ClearLoop is the first solution in the market that overcomes a growing industry challenge; counterparty risk with exchanges. This solution underpins a full prime services offering, connecting global exchanges, and enabling customers to trade and settle directly from the safety of their MPC-secured wallets. By reducing settlement time for transfers to a few milliseconds (without blockchain network dependency) and offering enhanced security measures, ClearLoop is rapidly reshaping the way asset managers trade and manage capital. In addition to industry-leading security certifications, Copper has one of the strongest insurance coverages in the industry from an A+ rated insurer, positioning the firm as the partner of choice for institutions seeking to safeguard their assets.

SUMMARY OF THE ROLE: At Maze, we're building AI-powered vulnerability management at a moment when generative AI is fundamentally changing what's possible in cybersecurity. Our engineering team is small, fast, and technically elite — and we're hiring an Engineering Director who is the same. This is not a coordination role. It is a senior technical leadership role for someone who earns respect by being on the tools, thinks deeply about architecture, and happens to be exceptional at growing engineers and running a high-performance org. You'll work in close partnership with our CTO, Santiago, taking ownership of a growing set of teams and tech leads as we scale from 20 to 35+ engineers. Your success will be measured the same way everyone's is at Maze: by the customer value and revenue impact of what your teams ship — not by process compliance, headcount growth, or delivery cadence. You'll have genuine accountability over a portion of the engineering org, with tech leads reporting to you, and you'll be expected to know your teams' codebases well enough to make good decisions, spot problems early, and earn the trust of every engineer who works with you. The person we're looking for has probably been the most senior technical person in a fast-moving 10–20 person engineering team — a CTO, VP, or Head of Engineering at a startup — and is ready to bring that energy and credibility to a company with more firepower behind it. If you want to stay close to the code, grow exceptional engineers, and help shape an org that will define how AI-native security companies are built, this is that role. YOUR CONTRIBUTIONS TO OUR JOURNEY: * Own engineering leadership for a growing portion of our org: Take clear accountability for a set of small, high-output product teams (typically 3–5 engineers each), with tech leads reporting directly to you. Ensure every team has unambiguous priorities, strong support, and everything they need to move fast. * Stay close to the technical work: Engage directly with architecture decisions, code reviews, and technical discussions across your teams. We expect you to spend meaningful time understanding what each team is building — not as a gatekeeper, but as a trusted technical voice who can contribute, challenge, and improve. * Grow the engineering leaders of Maze's future: Take ownership of career development, performance management, and coaching for tech leads and senior engineers in your teams. Build the kind of trust with engineers that comes from genuinely knowing their work, their growth areas, and their ambitions — not from generic 1:1s. * Drive cross-team coordination without creating bureaucracy: Own the planning and coordination layer that keeps multiple small teams aligned and unblocked. Keep it lightweight, decision-focused, and in service of engineering velocity — not process for its own sake. * Lead technical hiring: Take ownership of engineering hiring within your area, from defining the bar and shaping interview processes to closing exceptional candidates. The quality of who we hire is one of the highest-leverage things either of us can do. * Build the org we need to scale: Work closely with Santiago to design team structures, identify emerging leaders from within, and evolve how we operate as the team doubles. We grow leaders from the inside where we can — you'll be central to identifying, developing, and empowering the next generation. * Maintain technical excellence as we grow: Partner with tech leads to uphold code quality, shared engineering practices, and high standards across the org — without letting process replace judgment. WHAT YOU NEED TO BE SUCCESSFUL: * Technical credibility that engineers will respect: A strong engineering background with the ability to meaningfully engage in architecture discussions, code reviews, and technical decisions. You don't need to be the best coder in the room, but you need to be in the room for the right reasons. * Experience as the most senior technical leader of a small, high-output team: You've been a CTO, VP Engineering, or Head of Engineering at a startup — or a tech lead in a similarly fast-moving environment — where you were accountable for both technical outcomes and the people delivering them. You know what it looks like to lead 10–20 engineers, not just manage them. * Genuine people leadership, not just org design: A proven track record of performance management, career development, and growing engineers into leaders. You've had hard conversations, made difficult calls, and built cultures where high performance and high support coexist. * The hands-on instinct: You're drawn to being close to the work. You'd rather understand a problem by reading the code than by reading a status update. You see "staying technical" as a feature of your leadership style, not a tension with it. * Comfort with small-team operating models: Experience working in environments where teams are lean, fast, and expected to figure things out — not environments where scale compensates for speed. You know how to get a lot done with a little. * Strong hiring instincts: You've been deeply involved in engineering hiring — defining the bar, building processes, closing candidates — and you have strong opinions about what great looks like. * A business owner's mindset: You measure yourself by customer outcomes and revenue impact. You push your teams to understand why they're building what they're building, not just how. * Nice to Haves: * Experience in cybersecurity, AI, or security tooling — or a genuine interest in the domain and willingness to go deep quickly. * Founder or early-stage startup experience, particularly having built an engineering org from a small base. * Familiarity with agentic AI systems, LLMs, or ML-adjacent engineering — not as a researcher, but as someone who's built or led teams building on top of these technologies. * Experience managing distributed teams. WHY JOIN US: * Ambitious challenge: We're using generative AI — LLMs and agents — to solve some of the most pressing problems in cybersecurity today. The engineering challenges are genuinely hard, the domain matters, and we're early enough that the architectural decisions you make will define the platform for years. * Expert team: We are a team of hands-on leaders with experience at Big Tech and high-growth scale-ups, including teams behind multiple acquisitions and an IPO. We hire for quality over speed and it shows. * Impactful work: Cybersecurity is a force for good. The products your teams build directly help security teams protect their organisations against real attacks. The mission isn't decorative. * Build an AI-native engineering org from the ground up: We're designing the team structure, culture, and ways of working with a blank sheet of paper, in an era where agentic coding tools are changing what small teams can accomplish. You'll shape that from the start. * Real ownership and a clear growth path: You'll have genuine accountability over a meaningful portion of the organisation from day one, with a direct partnership with Santiago and significant equity upside as we scale.

Who we are Sapien is rethinking how finance teams operate in the age of AI. We’re building toward an autonomous CFO—systems that run company financials end-to-end. Our platform analyzes complex financial data in real time to increase decision cadence, prevent costly mistakes, and surface value. Sapien has caught multi-million-dollar errors, saved thousands of jobs, and returned significant dollars to customers’ bottom lines. We partner with traditional businesses—manufacturing, healthcare, restaurants, and large enterprises—to deeply understand and automate their financial workflows. We’re HQ’d by Madison Square Park in NYC and backed by General Catalyst, Neo, and top operators from Google, OpenAI, Microsoft, Ramp, and Stripe (over $9M raised). THE ROLE We're hiring a Founding BDR to own pipeline generation at Sapien. Your job is simple to state and hard to do: put Sapien in front of the right CFOs and finance leaders, at scale, and keep the sales team fed with qualified pipeline. This is not a dial-the-phone-200-times BDR seat. You'll own the top of funnel end-to-end: who we target, what we say, which channels we use, and how we iterate. You'll work directly with the founders and sales team, sit close to the deals you source, and be first in line for what comes next, whether that's an AE seat or leading the BDR team as we scale. WHAT YOU'LL DO Pipeline Generation * Build and run targeted outbound campaigns to finance executives, from ICP definition to messaging to sequencing to iteration. * Source, qualify, and progress leads through the funnel. You own top-of-funnel and pipeline velocity. Your scoreboard: qualified meetings booked and pipeline created. * Experiment relentlessly across new channels, angles, and tactics. Measure what works, kill what doesn't. Sales Support * Support live deals through research, competitive intel, call prep, and follow-ups. * Partner with the founders and sales on positioning, messaging, and narrative. You'll help shape how the market sees Sapien. Market Signal * Develop a deep understanding of finance workflows and the modern finance tech stack to sharpen every touchpoint. * Feed structured signal back to product and leadership: what's resonating, what's not, and where the opportunity is. What we're looking for * Builder mentality. You'd rather design the system than run someone else's playbook. You see gaps and fill them without being asked. * 1–4+ years of experience in GTM, sales, growth, consulting, or finance. You've done some version of pipeline work and want to go deeper. * Exceptional communicator. You write outbound that gets replies. You speak with confidence to senior finance leaders. Your writing is crisp and persuasive. * Process-obsessed. You build clean systems — CRM hygiene, dashboards, documented workflows. You don't let things slip through cracks. * AI-native. You use AI tools daily and you're energized by what's possible. You'll be expected to leverage AI across your workflows. * High agency. You operate with speed and urgency in ambiguous environments. You don't wait for permission — you identify what's next and do it. HOW YOU WORK (VALUES WE CARE ABOUT) * AI-native. You’re energized by applying AI to transform how businesses run. * Ambiguity-shaping. You turn nebulous problems into a first pass and drive to resolution. * Extreme ownership. You identify what’s next—and do it. If you say it, it gets done. * Speed & hustle. You bias to action and move with urgency without sacrificing quality.
