Software Engineer, Platform

Bretton AI is the leading AI agent platform for financial services. Companies like Robinhood, Mercury and Gusto trust us to automate mission critical work, starting with anti-money laundering and counter-terrorism investigations.

We’ve raised over $95M from Greylock, Y Combinator, Thomson Reuters Ventures and other top tier investors. We’re based in downtown San Francisco and our team comes from world-class organizations like SpaceX, Google, Netflix, Stripe, Plaid and more.

We’re hiring Platform Engineers to build and operate the infrastructure that powers compliance at scale.

You’ll own reliability, performance, and scalability across our core systems. You will design Postgres schemas, optimize queries, build high-throughput services, orchestrate long-running workflows (Temporal), and maintain our commitment to 99.9%+ uptime for customers processing thousands of cases per day.

You’ll write production backend code, design distributed systems, and own the infrastructure that empowers our product teams to ship fast without breaking production.

• Build APIs and services that handle thousands of concurrent requests.

• Architect ingestion → assessment → delivery pipelines for our cases.

• Implement Temporal workflows for long-running, stateful processes.

• Design and optimize PostgreSQL schemas and queries for our compliance workflows.

• Own CI/CD, deployments, and infrastructure-as-code, and drive observability through logging, tracing, and metrics.

• Debug slow queries, memory leaks, and race conditions in our production environment.

• 4+ years (Engineer) / 6+ years (Sr. Engineer) / 8+ years (Staff Engineer) of backend or infrastructure experience.

• Strong systems fundamentals, including distributed systems, databases, APIs, and concurrency.

• Proven production experience, including debugging live systems, incident response, and on-call rotations.

• PostgreSQL expertise, including query optimization, indexing, schema design, and migrations.

• An ownership mindset: you close the loop, write postmortems, and prevent the recurrence of issues.

• Languages: TypeScript/Node.js (primary), SQL (advanced), Python (nice to have).

• Databases: PostgreSQL/Supabase, RLS, query planning.

• Workflow: Temporal (preferred) or Airflow/Prefect/Cadence.

• Cloud/Infra: AWS/GCP/Azure, Docker, CI/CD (GitHub Actions).

• Monitoring: Datadog (or Grafana/Prometheus/New Relic/Sentry).

• Fintech/RegTech experience (security, audit logging).

• AI/LLM infrastructure experience (prompt orchestration, token limits, cost management).

• Experience with high-throughput systems and chaos/resilience testing.

• VPC architecture and cloud networking (security groups, private endpoints, compliance requirements).

You are motivated by the opportunity to join a startup at our stage because you want to build something fast and have a direct impact—not because you need extensive structure. You are energized by combining technical work with customer interaction. You love solving open-ended problems, asking good questions, and structuring solutions without needing perfect specifications upfront.

You make pragmatic decisions with incomplete information and proactively pull in the right people to overcome blockers. You are adaptable when priorities shift and have a growth mindset. You understand the broader system you’re working in—not just what the AI does, but how it fits into the customer’s full workflow.
