Job Description
Senior Software Engineer — New York, NY · Hybrid · Full-time · $220K–$270K + equity
About the CompanyOur client is a seed-stage, venture-backed AI startup bringing modern software to a large, traditionally underserved industry — building a fully managed platform that ingests, organizes, and analyzes complex documents and data so its customers can make faster, better-informed decisions. They run a lean, AI-native engineering team where individual engineers carry real ownership over both product and architecture. Founded 2020 · ~20 people · Industry: AI / Enterprise Software.
The RoleWe're representing our client in a search for a senior backend engineer to join as a hands-on IC in an early-stage environment — shipping production services, driving key architectural decisions, and mentoring junior engineers, with a clear runway to a lead role in the near term.
What you'll be doing
- Design, build, and operate production-grade backend services and data pipelines on a Python + AWS serverless stack
- Make architectural and system-design decisions, using modern AI coding tools to move quickly
- Own features end-to-end across a primarily backend codebase, with occasional front-end work in React
- Work directly with customers to turn ambiguous requirements into shipped software
- Mentor junior engineers through code review, design discussions, and pairing
Tech stack: Python, AWS (Lambda, Step Functions, serverless), REST APIs, microservices, event-driven architecture, React
Requirements- 5+ years in backend software engineering
- Experience as a founding engineer or early hire at an early-stage B2B SaaS startup, with genuine end-to-end ownership
- A track record of owning production backend systems, not just contributing to them
- Advanced, production-level Python skills
- Strong hands-on AWS experience, particularly serverless (Lambda, Step Functions)
- A product mindset and comfort speaking directly with customers to clarify what needs building
- Based in or near New York City and able to work on-site three days a week (Midtown)
- A BS in Computer Science or a related STEM field, or an equivalently strong startup engineering track record in its place
- Prior tech-lead or mentorship experience guiding junior engineers
- Familiarity with AI coding tools and agentic development workflows
- Build the core platform for a large industry that modern software has barely reached
- Small, well-backed, AI-native team where engineers own product and architecture outright
- Senior IC role with a clear near-term path to a lead position
- Competitive base plus meaningful early-stage equity
- Location: New York, NY
- Work policy: Hybrid — 3 days/week in-office (Midtown)
- Compensation: $220K–$270K + equity
- Visa sponsorship: Not available for this role
- Employment type: Full-time
