Staff Full Stack Engineer - Sell Side Engine

This is a highly hands-on Staff Engineer role focused on solving complex technical problems within a rapidly scaling energy technology environment.
You will join a small, high-impact product squad responsible for rebuilding the systems that support renewable energy origination, contracting, onboarding, and growth.
The role combines deep backend and systems engineering with the flexibility to contribute to frontend development when needed.
You will make architecture-level decisions across integration-heavy systems, working with pricing, data, billing, and risk platforms.
A major focus will be turning manual and error-prone commercial processes into scalable, automated products that can support new business categories.
You will work with significant autonomy, operating within ambiguity and taking complex problems from definition through production delivery.
This is an opportunity for an exceptional engineer to directly influence critical market infrastructure while helping build the technology behind a more transparent and efficient energy ecosystem.

• Deep technical expertise in backend engineering and systems design, with a proven track record of making architecture-level decisions for complex, integration-heavy systems.
• Strong professional experience with Python and AWS serverless technologies, including Lambda, API Gateway, DynamoDB, and EventBridge.
• Solid understanding of event-driven architectures and distributed systems.
• Full Stack or Backend Engineering experience in a startup, scale-up, or fast-paced product environment, with ownership of complex projects from inception through delivery.
• Ability to work effectively without a complete specification, turning an ambiguous problem into a practical, well-scoped, and shippable technical plan.
• Demonstrated experience delivering projects where critical dependencies are owned by other teams, requiring strong collaboration and influence without direct authority.
• Strong product mindset and ability to connect technical decisions to commercial outcomes and customer or business value.
• Comfortable working hands-on across the stack, with React and TypeScript experience considered a plus rather than a core requirement.
• Strong engineering judgment, attention to quality, and ability to reason about scalability, reliability, system boundaries, and failure modes.
• Excellent communication and collaboration skills, particularly when working across technical and organizational boundaries.
• Experience mentoring engineers or setting technical direction is desirable but not required.
• Experience in energy, fintech, or another regulated or high-stakes commercial environment is advantageous.
• Exposure to workflow orchestration, real-time pricing engines, or event-driven systems is a plus.
• Experience creating new product lines or technical capabilities from scratch is highly desirable.
