About The Position

Multiple venture-backed AI and enterprise-software companies are hiring product-minded engineers to own customer-facing systems from concept through production. This role involves building and shipping end-to-end product features across modern frontend, backend, and data layers. You will own projects from problem definition and technical design through launch, measurement, and iteration. Collaboration with founders, product leaders, designers, and customers is key to translating ambiguous needs into reliable software. The position requires making pragmatic architectural decisions that balance speed, quality, and long-term maintainability. Additionally, you will use modern AI development tools and integrate LLM or agentic capabilities into production workflows, while raising engineering standards through thoughtful reviews, testing, observability, and operational ownership.

• Depth in TypeScript/JavaScript and a modern frontend framework such as React or Next.js.
• Backend experience with Python, Node.js, Go or a comparable language, plus relational databases and APIs.
• Evidence of owning meaningful products or features from 01 or through major scale-up.
• Comfort operating with incomplete requirements, rapid iteration and direct business accountability.
• Clear communication and the ability to work effectively with technical and non-technical stakeholders.

Nice To Haves

• Early-stage or founder-level ownership experience.
• Experience with AI-native products, LLM applications or data-intensive SaaS.
