## About the Role

* 7 to 25 years building software, with at least 5 years at a senior level, owning full-stack web applications end to end from design through deployment.
 * A track record at product-led technology companies where the software itself was the product, such as high-growth VC-backed startups or major tech companies, rather than internal tooling at non-tech firms.
 * 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 concrete examples of complex systems you have shipped.
 * Experience building and scaling high-throughput distributed systems in the cloud on AWS, managed with infrastructure-as-code such as Terraform.
 * Working fluency across a modern web stack: React, Node/Express, GraphQL/Apollo, and PostgreSQL.
 * A sharp eye for security, given the sensitivity of the data involved.
 * Able to work remotely on U.S. business hours, with a history of steady tenure and clear progression (typically at least 2 years per role).

Nice to Haves

 * Experience designing and scaling complex relational database schemas.
 * Background in fintech.
 * Familiarity with modern AI product development practices such as evals, experiment design, and dataset curation.
 * An SRE-minded approach to building reliable, observable, low-maintenance infrastructure.
 * An active GitHub and personal side projects.

## Description

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.

Founded around 2020 · Fully remote team · Industry: Fintech, AI, B2B enterprise software

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.
