This RoleWe're looking for an engineer who lives and breathes the current wave of AI. Someone who's building with agents outside of work, has opinions about the latest model releases, and wants to apply that energy to production systems used by large enterprises.
As a Senior AI Engineer at Spara, you will:
- Build and iterate on the AI systems that power our agents across chat, email, voice, meeting assistants, and lead enrichment. We ship new agent capabilities regularly, and the surface area is expanding fast.
- Work across multiple agentic systems, both customer-facing and internal. You won't be stuck on one thing.
- Improve retrieval, ranking, and response quality in a system that handles real customer conversations every day. The feedback loops are tight and the stakes are real.
- Contribute to how we evaluate and measure quality across the platform. We care a lot about evals and are investing heavily here.
- Ship to production multiple times a day using a modern stack: FastAPI/Python, React/TypeScript, Postgres + pgvector, multiple foundation models (OpenAI, Anthropic), Google Cloud, Docker, GitHub Actions.
What We're Looking For- 4+ years of engineering experience with meaningful time spent working with LLMs and related technologies
- At least one startup under your belt. You know what it's like to build fast with a small team and wear multiple hats.
- Deep familiarity with the agentic AI landscape. You follow what's happening, you've tried the new tools, you have opinions.
- Proven ability to ship ML/AI systems in production, not just prototypes
- Strong software engineering fundamentals across the stack
- You're excited about the messy, fast-moving parts of building an early-stage AI company
Nice to have:- Experience with retrieval systems, search, or NLP
- Advanced degree in ML or a related field
Location & Work ScheduleHybrid: 3 days per week in our office in downtown Manhattan (World Trade Center), with the option to work remotely on Wednesdays and Fridays.
Compensation & Benefits- Health, dental, and vision insurance
- Flexible PTO
- Collaborative environment with experienced engineers solving hard problems together
- Real ownership over product direction from day one
- In-office culture in NYC with flexibility for work-life balance
