Staff Software Engineer

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 Staff 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

• Own and architect core systems end-to-end, driving design decisions across the platform
• Build and scale AI-powered software systems that power real-world financial workflows
• Lead complex, ambiguous projects from problem definition → production, setting technical direction along the way
• Partner closely with product and leadership to shape both technical and business strategy
• Drive engineering excellence across the team (code quality, system design, reliability, scalability)
• Identify and build reusable abstractions, infrastructure, and tooling to accelerate development velocity

Who You Are

• 8+ years of experience as a software engineer, with time operating at a staff or equivalent level
• 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
• Comfortable operating in high-ambiguity, fast-moving environments with high ownership
• Strong communicator who can influence technical decisions across teams

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
