Full Stack Engineer

• Design and implement serverless API services using Python/FastAPI on AWS Lambda - performance, reliability, and maintainability matter

• Own MongoDB Atlas data modeling decisions: schema design, indexing strategy, aggregation pipelines, and Atlas Change Streams for event-driven workflows

• Build and maintain async processing pipelines: SQS, Step Functions, EventBridge - designing for idempotency and fault tolerance from the start

• Contribute to CDK infrastructure-as-code - own what you deploy

• Implement Auth0-based multi-tenant authorization patterns with role-based access control across customer and internal surfaces

Full Stack Contributions

• Build React features end-to-end when needed - you don’‘t need to be a frontend specialist, but you can own a feature from API to UI

• Collaborate with frontend engineers (Vite/React/TypeScript) on API contracts, data shapes, and integration patterns

• Review frontend PRs for API usage and integration correctness

Integrations & Platform

• Own integrations with third-party systems: Sage Intacct, SignNow, OnlyOffice (WOPI), and new partners as the platform grows

• Build secure, observable integrations with proper retry logic, DLQs, and audit trails

• Contribute to the platform’’s MCP server and AI document processing pipeline

Future Leadership Path

• As the team grows, take on technical leadership of a backend squad - code reviews, architecture decisions, mentoring

• Help define engineering standards: testing strategy, PR conventions, observability practices

• Be the person junior engineers come to when they’‘re stuck on backend architecture
