Job summary

Tem-Energy is seeking a Staff Software Engineer to join Origination & New Products, a small squad focused on integrating with Rosso, Data and Billing. This is an IC role centered on hard technical problems, not a leadership track.

You’ll own architecture decisions, ship novel product categories, and drive impact across backend systems while remaining comfortable moving into React/TypeScript frontend when needed in a fully remote, flexible setup.

Qualifications

• Deep technical depth in backend and systems design, with a track record of owning architecture-level decisions on complex, integration-heavy systems.
• Comfortable in our core stack: Python, AWS serverless (Lambda, API Gateway, DynamoDB, EventBridge), and event-driven architectures. React/TypeScript exposure is a plus but not the bar.
• Comfort operating without a full spec: able to take a defined slice of an ambiguous problem and turn it into a shippable plan.
• Experience delivering work where a critical dependency sits with a team you have no authority over.
• Proven product delivery experience: experience as a Full Stack or Backend Engineer in a startup or fast-paced product environment, with ownership of complex projects from start to finish.

Responsibilities

• Go deep on hard systems: Own architecture-level decisions on integration-heavy systems, reasoning clearly about boundaries, contracts, and failure modes.
• Build for ambiguity: Take a piece of an undefined, commercially-driven problem and turn it into a shippable plan, within the direction your squad lead sets.
• Work across boundaries: Deliver on dependencies that sit with teams you have no authority over, such as Rosso, Data, and Billing, getting integrations right without needing to own the relationship.
• Build with impact: Design, build, and ship the hardest parts of the new-product build sequence yourself, backend-first but comfortable moving into the React/TypeScript front end when it matters.
• Maintain high standards: Write clean, well-tested code, contribute to code reviews, and help improve team practices and documentation.
