Note: The job is a remote job and is open to candidates in USA. Charter Global is looking for a Senior Software Engineer to join their team working on the Clinical Data Layer, a cloud-native platform for standardizing clinical trial data. The role involves designing and building features across a Python/AWS backend and a React frontend, with a focus on creating impactful data pipelines for regulatory submissions and clinical trial outcomes.
Responsibilities
- Design and extend the SDTM transformation engine — AWS Step Functions orchestration, Lambda workers, and Databricks write paths
- Build and evolve the GraphQL/AppSync API and React frontend used by analysts to author mapping specifications
- Own infrastructure-as-code changes across service Terraform stacks and shared infrastructure
- Participate in code review, architecture discussions, and on-call rotation
- Mentor engineers newer to the stack or clinical data domain
Skills
- 7+ years of professional software engineering experience
- 10+ years for Lead Developer role
- Python proficiency — you're comfortable with Lambda Powertools, pytest/pytest-bdd, and writing clean, testable Python in a monorepo context
- AWS depth: Lambda, Step Functions, S3, DynamoDB, and IAM — you can reason about cost, latency, and failure modes, not just get things working
- GraphQL / AppSync experience — schema design, resolvers, and consuming AppSync from a React client
- React + TypeScript — comfortable contributing to a Vite/Cloudscape SPA without being a frontend specialist
- Infrastructure as code with Terraform — reading, writing, and debugging multi-stack configurations
- Databricks or similar large-scale data processing platforms
- Clinical data standards (CDISC SDTM, ADaM) or regulated-industry software development experience (GxP, 21 CFR Part 11)
- A good grasp of event-driven and distributed system patterns — fan-out/fan-in, idempotency, at-least-once delivery
