The Role
A Technical Product Manager (TPM) bridges the gap between technology and business, playing a critical role in guiding the
development of products that align with both customer needs and company goals. They combine technical expertise with strategic
thinking to translate business requirements into actionable product features, engage with team leadership on prioritizing features
based on value, and ensure seamless communication between engineering, design, and business teams. The TPM understands the
technical details and ramifications of product decisions and collaborates closely with developers to solve complex challenges,
make informed trade-offs, and deliver high-quality, scalable solutions. Their role is essential because they help balance product
features against technical complexity, optimize resources, reduce development risks, and ensure that products not only meet market
demands but are also technically feasible and aligned with the company’s vision and objectives.
The Technical Product Manager (TPM) role at Sparta encompasses product strategy and execution, design and architecture. You
partner with product experts, commodity owners, product designers and software developers to make sure we’re shipping high quality
products on time. You define and track product delivery milestones, identify risks and blockers, remove roadblocks and anticipate
customer needs.
You will work on multiple Sparta products across energy commodity verticals. This position requires a combination of project
management, technical proficiency in data software systems and exceptional execution skills, to successfully drive product
projects.
You are a team player, a person who loves enabling a team, fixing problems, scaling technical solutions, and always embraces the
best idea, even when it is not your own.
This role can be based out of London, Madrid or Barcelona, working on a hybrid basis- ideally 2- 3 days a week in the office with

As a Technical Product Manager, you’ll be defining our product direction in close collaboration with our talented Engineering teams. You’ll own product areas end-to-end and ensuring we ship the right things at pace. You’ll bring technical credibility to every conversation and into product decisions that matter. You’ll work alongside the VP, Product in a product function that punches well above its size, complementing our engineering and ML teams with product leadership, aligning our roadmap across sales, research and GTM. This is a role for someone with genuine technical depth who wants to grow into more, using their hands-on background to drive product impact in one of the most technically interesting areas in AI today. What will you be doing: * Shipping Voice AI products end-to-end: From discovery and definition through to delivery and iteration. Focusing on shipping value to customers, not just features. That means owning the success definition for key product areas: choosing the right metrics and using data to drive iteration. * Speaking directly to customers: Running your own interviews with users building with our Speech APIs for use cases such as voice agents, medical scribes and more. Understanding their needs and communicating them to the business. * Evolving the product roadmap for your area: Bringing customer and market insight as well as technical context to build defendable prioritisation decisions. * Partnering closely with ML researchers and engineers: To translate technical requirements and realities into product decisions. Understanding what trade-offs need to be agreed and how to deliver efficiently. * Working with sales and GTM: Defining how we package and position what we build, so that what we ship stands out in a competitive market. * Helping define what great product looks like at Speechmatics: Being part of a product culture built on rigour, speed and deep curiosity. Who we’re looking for: * Product experience: You've taken a product from problem definition to delivery multiple times and measured the impact. * Technical depth: You’ve worked in software engineering, ML, data science or a related technical field. You're comfortable building scripts and quick prototypes, using the latest AI tools to move fast and validate ideas before committing engineering resource. * APIs and deployment: Familiarity with API-based products and SaaS or on-premise deployments would certainly help. * ML Product fluency: You understand that shipping an ML model isn't like shipping a software feature. The definition of "ready to ship" is not black and white, evaluation isn’t pass or fail. * Experience working directly with teams that train, evaluate and ship models is a real advantage. If your background is outside ML, we'll want to understand how you build technical fluency quickly and any relevant experience. * Data instinct: You are comfortable digging into model evaluation results, asking whether the test data reflects real-world conditions, and understanding what a benchmark result does and doesn't tell you. * Engineering credibility: You can engage with ML engineers, researchers and developers from day one, earning trust by listening and learning, rather than title. * Comfortable with ambiguity: AI is moving quickly and so are we. You bring enough market and technical awareness to have a point of view on where things are heading, and you use that to shape roadmap decisions rather than just react to them. We encourage you to apply even if you do not feel you match all of the requirements exactly. The list of requirements is intended to show the kinds of experience and qualities we’re looking for, but it is not exhaustive. If you are interested in the role, the team, and our mission, we would love to consider your application. We are always open to conversations and look forward to hearing from you. Who we are: Speechmatics is the leading expert in Speech Intelligence, and uses AI and Machine Learning to unlock business value in human speech worldwide.

Joining us means working with some of the smartest minds around the world, focused on cutting-edge projects and deploying the latest techniques to disrupt the market. We believe in putting people first; we’ll do all we can to help you develop your skills and give you the tools you need to thrive. Our Focus Fridays give you an undisturbed day of focus, offset with Together Tuesdays when we have our team meetings, so you've always got the right balance. We have structured a hybrid approach that includes 2-3 designated office days each week. This arrangement ensures that while we embrace the advantages of remote work, we also maintain the vital connection and synergy that only in-person interactions can foster. This is only the beginning; we’re looking for amazing people like you to continue our journey… What we can offer you: No matter what stage of your career you’re at - from paid internships and first-job opportunities through to management and senior positions - we’ll support you with the training and development needed to reach your career aspirations with us. There really is no shortage of opportunities here for you to get involved and collaborate with those around you to deliver your best work. We offer incredibly flexible working, regular company lunches, and birthday celebrations. But that’s not all. We’ve spoken to our teams to find out what they want. From Private Medical, and Dental for you and your family, through to global working opportunities, a generous holiday allowance and pension/401K matching, we want to make sure our employees and their families are looked after. Every employee will receive a working from home allowance for tech or home office equipment (on top of your choice of laptop and accessories of course). Our approach to parental leave is designed to support employees globally. While this varies by geo, we have support in place for parents (including adoption assistance and reproductive health services) to ensure they have the time and financial resources needed to care for their growing families. At Speechmatics, our mission is simple: Understand Every Voice out there. That's not just about our tech – it's the heart and soul of who we are. We welcome different experiences, viewpoints, and identities. For us, it’s not just the right thing to do; it’s our catalyst for sparking innovation and creativity. Our teams thrive in an environment that celebrates and supports everyone – no matter their gender, identity or expression, race, disability, age, sexual orientation, religion, belief, marital status, national origin, veteran status, pregnancy, or maternity status. But we don’t just open the door to diversity – we actively welcome it. Why? Because we believe every unique voice adds something special to our team, leading us to smarter solutions and a better workplace. So, come as you are and join our Speechling community. We’re building a place where every voice not only gets heard but is also respected and valued.
