The Role

As a Staff Engineer, you’ll define and implement the core systems powering Synquery. You’ll work hands-on across the stack, contribute to architectural decisions, and guide product-aligned engineering efforts.

You’ll also help establish our technical standards, influence hiring, and mentor teammates. This role is ideal for an experienced engineer excited to wear multiple hats-builder, architect, leader-and make foundational contributions to a fast-moving AI product.

• Innovate: Leverage emerging technologies in AI/ML, generative AI, and hybrid search to enhance product capabilities.
• Shape Engineering Culture: As a founding team member, influence team practices, tooling, and values from the ground up.

Qualifications

• Experience: 7+ years in full-stack software development, ideally with experience in early-stage or high-growth startups.
• Technical Stack: Proficiency in Python (FastAPI), TypeScript (Next.js), PostgreSQL, AWS, Docker. Experience with LLM APIs (GPT, Claude, etc.) and/or vector DBs (e.g., Pinecone) is a big plus.
• Product Mindset: Strong collaboration with product teams, with an ability to balance speed, quality, and user impact.
• Startup Experience: A dynamic, entrepreneurial approach to problem-solving. Thrives in fast-paced, ambiguous environments with a “get-it-done” attitude.
