Skills
Must have
- 7–25 years building software, with at least 5 years at a senior level owning full-stack web apps end to end
- Track record at product-led technology companies where the software itself was the product (e.g., high-growth VC-backed startups or major tech companies)
- Genuinely full-stack: roughly 50/50 or 60/40 split across frontend and backend; backend-only or frontend-only profiles not a fit
- Deep, recent, hands-on TypeScript experience in production with concrete examples of complex shipped systems
- Experience building and scaling high-throughput distributed systems on AWS, managed with infrastructure-as-code such as Terraform
- Working fluency across React, Node/Express, GraphQL/Apollo, and PostgreSQL
- Sharp eye for security given the sensitivity of the data involved
- Able to work remotely on U.S. business hours, with steady tenure and clear progression (typically at least 2 years per role)
Nice to have
- 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
- SRE-minded approach to building reliable, observable, low-maintenance infrastructure
- Active GitHub and personal side projects
Full description
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.
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.
Requirements
- 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).
