YOUR MISSION: As a Solutions Architect, you will be a pivotal force in driving the success of our commercial partnerships. You'll act as the crucial technical liaison, bridging the gap between our external partners and internal product development teams - ensuring that the solutions we shape with prospects are both commercially compelling and operationally deliverable. You help prospects understand how their investment use case maps to the lemon.markets platform and what it takes across teams to bring that use case to life. This role offers a unique opportunity to influence the entire partner and product lifecycle, from supporting pre-sales go-to-market initiatives to ensuring seamless partner onboarding post-sales. You guide prospects from post‑discovery into deep qualification, uniting internal teams around a shared understanding of requirements, risks and solution paths. You turn complexity into clarity - structuring workshops, mapping operating models and coordinating across disciplines to make sure we design solutions that work end‑to‑end. You are a strategic thinker, a problem solver, and a passionate advocate for both our partners and our product. You thrive in a dynamic, collaborative environment and are driven by the challenge of building lasting partnerships that drive innovation and growth. This is not a pure technical architecture role. It’s a highly cross‑functional, business‑aware role where you connect the dots across departments, shape how we present our product, and ensure we deliver comprehensive solutions - ultimately enabling Europe’s top FinTechs, Banks and Wealth Managers to build modern investment experiences. YOU WILL: * Act as the cross‑functional bridge between Product, Engineering, Operations and GTM - ensuring all teams are aligned on the prospective partners needs and solution direction. * Cross-collaborate across teams to validate feasibility, clarify requirements and shape the best solution forward. * Work closely with GTM to win prospects’ trust in our technical solutions and win deals. This will comprise of the following: * Serve as the primary technical point of contact for prospective partners, and own the first technical impression, articulating the value proposition of our platform and demonstrating its capabilities * Conduct thorough technical discovery sessions to understand partner requirements and design tailored integration solutions, mapping the partner needs to our platform capabilities * Contribute to the creation of technical proposals as part of RfIs/RfPs, accurately reflecting partner requirements and connecting into our current and planned product capabilities * Stay abreast of industry trends and competitive landscape, providing technical insights to support sales and marketing efforts * Work closely with Partnerships to drive seamless, best in class experience for our partners. This will comprise of the following: * Engage with and maintain strong, trusted relationships with CTOs and other technical leads and their teams, serving as their point of contact for technical inquiries and support * Provide expert guidance on API usage, integration best practices and troubleshooting, helping partners navigate the full breadth and depth of our APIs * Lead the technical aspects of the partner onboarding process, providing comprehensive guidance and support throughout the integration lifecycle * Collaborate with internal product and engineering teams to coordinate the seamless rollout of new features and updates to partner integrations * Establish a scalable model for ongoing technical support, ensuring efficient troubleshooting by proactively engaging engineers where needed, reducing bottlenecks, and enabling broader team involvement in issue resolution YOU WILL BE SUCCESSFUL IN THIS ROLE IF: * You have experience in solution consulting, pre‑sales engineering or similar client‑facing roles within complex financial services and enjoy the rollercoaster ride of sales. * You have a solid technical understanding and familiarity with securities services, market infrastructure and regulatory frameworks. * You can translate complex requirements into clear, pragmatic solutions that balance product capabilities, regulatory constraints and operational realities. * You are a strong (fluent) communicator in German and English who can simplify complexity and inspire confidence across all seniority levels, including C‑level. * You thrive in cross‑functional environments and collaborate naturally with Product, Engineering, Operations and GTM. * You produce high‑quality prospect‑facing materials - from Target Operating Model diagrams to technical specifications - with a strong attention to detail. * You are cold-start capable. You can walk into a meeting with minimal context, rapidly absorb what matters, and lead the room toward a clear technical path forward. * You thrive on ownership. “This is not my job!” is not part of your vocabulary - you are intrinsically motivated to deliver value by taking initiative and challenging the status quo. HOW WE TAKE CARE OF YOU: * 🚀 Compensation package: We offer you a competitive salary, based on your experience and the value-add you bring to lemon.markets. * 🕑 Flexible working hours: We trust people to choose when they work best and avoid a rigid 9 to 5 mindset. You decide on the rhythm that helps you do your best work, with only shared core hours from 12:00 to 16:00 to support collaboration. * 🏢 Hybrid work setup: You can work from anywhere in Germany within a hybrid model. At the same time, in-person collaboration is a key part of our culture. That being said, individual contributer lemoneers work 4 days or more per month on-site in our Berlin office, spending quality time together with the team at events, onsites/offsites or over team dinners. * 📈 Grow with us: We take your personal development seriously! You’ll get regular mentorship and stretch opportunities, plus a clear career development framework with frequent feedback conversations so you always know where you stand, and what to do to level up. * 🌱 People & culture: You’ll feel our culture in the small things, like polaroids from our lemoneers’ first day, Friday food market strolls at Maybachufer, and our monthly new-joiner breakfast. But also in the bigger things: celebrating the onboarding of new partners, growing our teams, and owning a strong discussion culture. * 💛 Perks & benefits: We choose benefits that add actual value. We sponsor a Deutschlandticket for employees on unlimited contracts, plus 50% off on Beatvest - our partner for financial education and investing. * 🏝 Workation: Get out of here! At lemon.markets you can work remotely from anywhere in the EU for up to 10 consecutive days at a time, and up to 60 days per year in total.

If you feel this role could be a great match for you even if you don’t tick every box, we’d still love to hear from you, please apply. You have any questions?

PLATFORM ENGINEER (M/W/D) PERMANENT EMPLOYEE, FULL-TIME · BERLIN (HYBRID)  THE IMPACT YOU WILL MAKE From socks, and petfood, to cosmetics, charles is helping countless brands reach their loyal customers every day, one conversation at a time. As a Platform Engineer at charles, you’ll help drive our product and infrastructure forward, enabling us to revolutionize conversational commerce. You’re a generalist with a passion for infrastructure and operations. You’ll work closely with the other Engineers to build scalable, high-performing systems, while improving system architecture, resolving tech debt, and ensuring seamless user experiences. Your contributions will result in reliable, data-driven solutions that support millions of users and push the boundaries of messaging-driven commerce. THIS IS WHAT YOU WILL BE DOING You'll build and operate our internal developer platform: the core services, APIs, and infrastructure that every product team builds on top of. That means writing software, not just configuring it, and standing up infrastructure that holds up under real production load. * You will be a part of a team that designs, develops, and operates the core services, APIs, and infrastructure that every product team builds on top of. Examples: building a billing API, maintaining Kubernetes operators, building an authentication broker, optimizing performance in our core monolith, and improving security in our link shortening service. * You will regularly partner with product teams to investigate issues, learn their use cases, and ship platform changes that hold up in production. * You'll join our on-call rotation as part of our "you build it, you run it" philosophy. * You'll have real room to drive cost and reliability initiatives that have measurable, company-wide impact. * You'll build the automations that make our whole software development lifecycle faster and more robust. YOU'LL FIT GREAT WITH THESE SKILLS AND VALUES * 3+ years of software engineering experience. You're a generalist - comfortable moving between writing a service, debugging infrastructure, and improving a pipeline in the same week. * You can build and ship production services in Go or TypeScript; not just scripts and glue. You also know Bash and have the judgment to pick the right tool instead of forcing your favorite one. * You can build and operate cloud infrastructure that survives real production workloads, ideally on GCP. * You've worked with GitHub Actions or similar CI/CD tools, and you know what a healthy and efficient pipeline looks like. * You have a solid grasp of scalable system design, distributed systems, cloud technologies, and how to roll out infrastructure changes. * You're comfortable with remote work and asynchronous communication. You also know that good collaboration needs visibility and cooperation, not just output. * You use AI tools effectively without handing over the steering wheel. * Product and business sense: you understand customer needs and focus on solving the right problems, not just building technically interesting solutions. * You're a self-directed learner. You don't need to know our whole stack on day one, but when you hit something unfamiliar, you dig in, ask good questions, and follow through. We'll give you room and context to grow; you bring the drive. Meeting all requirements is not necessary to apply. We encourage candidates who meet some but not all of these qualifications to submit their application.
