Senior/Staff Software Engineer

About the Company

---------------------

Our client is a venture-backed company building AI-native software to automate a large, traditionally manual corner of financial services. They are well past early traction, with major enterprise customers live on the platform and several more in late-stage sales, and they run a fully remote team with multiple years of runway. This is an environment built for engineers who thrive on autonomy, ownership, and shipping quickly.

The Role

------------

This is a senior/staff full-stack individual-contributor role where you ship to production early and quickly take ownership of mission-critical work.

### What you'll be doing

• Designing, building, and launching complex, multi-step AI agents that customers rely on to automate operational workflows.
• Integrating with third-party services APIs for document generation, automated decisioning, and fraud prevention.
• Building the next generation of the platform's job-processing infrastructure on AWS for a more observable, reliable back end.

Tech stack

TypeScript, React, Node/Express (containerized), GraphQL/Apollo, PostgreSQL, AWS (ECS, RDS, ElastiCache, Kafka, ElasticSearch), Terraform.

Requirements

• Genuinely full-stack, splitting your time roughly evenly across frontend and backend (around 50/50 or 60/40 either way). Strongly backend-only or frontend-only profiles are not a fit for this role.
• Deep, recent, hands-on TypeScript experience in production, with
