About Saris AI

We're a San Francisco & Montreal based applied AI startup that's building the future of work in the banking industry. We are tackling a $100 billion/yr problem, doubling every quarter and pushing the boundaries of what’s possible with multi-turn AI agentic systems

Our goal is to tackle the type of automation problems that require long-context reasoning, tool orchestration across legacy systems, and strict compliance loops: the ones without known answers.

We’ve shipped real agents that handle real customer workflows in production. With a growing customer base and live deployments, we’re scaling up fast and looking for deeply technical builders who want to have outsized impact early.

Our core engineering team is looking for a builder, a Software Engineer who thrives in early-stage (ambiguous) environments. You’ve seen products through from v1 to scale, and you love designing clean systems that last.

Your mission is to

• Design, develop, test, deploy, maintain, and enhance practical AI-powered software solutions for the fintech industry.

• Own project timelines by managing priorities and delivering high-quality features.

• Drive product and business decisions as a core contributor, helping to define and shape both the technical foundation and strategic direction.

• Participate and foster best practices including code reviews, testing, etc.

Who You Are

• Demonstrated backend/fullstack engineering experience, ideally in SaaS in high-impact projects

• Deep experience with Python (Django, Flask, FastAPI), TypeScript (React), Docker, and cloud platforms (AWS/GCP)

• Strong experience with designing, building and scaling distributed systems

• Strong background in relational + non-relational databases (PostgreSQL, Redis)

• API design chops (REST, GraphQL), deployment know-how

Bonus Points If You

• Have built complex workflow orchestration systems

• Know your way around cloud infra

• Have experience building integrations or data pipelines

• Love mentoring and growing teams

Why Join Saris AI?

• 💲Competitive compensation with premium benefits and equity package.

• 🤝Work with a stellar team of engineers, builders, and leaders; including repeat YC founders with a successful exit (Ready Education).
