Senior Software Engineer (AI Focus)

Senior Software Engineer (AI Focus)


Our client is a fast-growing SaaS company scaling rapidly, and they are now looking for a senior engineer to build AI-powered systems that sit at the core of how the business operates and grows.


This is a high-impact, high-autonomy role at a company solving real problems for real revenue. You will work directly alongside the founders and senior engineering leadership, owning the design and delivery of production AI systems, from the first architecture decisions through to release and iteration. The starting focus is bringing order to a sprawl of disconnected internal systems, with plenty more to build as the company grows.


This is a senior role for an engineer first. We are looking for someone with a strong software engineering foundation who has moved into AI and can show real, production-grade work.



What you’ll do:


Design and build production AI systems and internal tools that remove friction across the business
Build agent-based and LLM-powered workflows, taking them from idea to reliable, observable software
Untangle and integrate disconnected systems, and set the technical direction for what replaces them
Apply strong systems-design thinking to ambiguous, undefined problems
Work cross-functionally with GTM, CS and engineering to identify bottlenecks and ship solutions end to end
Set engineering standards for AI work, including testing, evaluation and quality gates



You are:


A senior software engineer with a solid track record of shipping and owning production systems
An engineer who has moved into AI, with hands-on experience building LLM applications and agents (tool calling, RAG, evals, observability)
Strong in TypeScript or Python, tool choice is yours
Comfortable with ambiguity and building from scratch with little oversight
Able to work directly with founders and senior leadership, turning business pain into technical solutions
Hungry to solve hard problems and move fast



Details:


New York City, hybrid, 3 days a week on-site
Competitive base salary + bonus
Join a fast-growing team that isn’t slowing down
Direct access to the founders, with high visibility into company-wide strategy
