Full Stack Engineer - Research Systems

What you'll do

• Design, implement, and ship full‑stack features across React front‑ends, Node.js services, and Java back‑end components, with an emphasis on performance, reliability, and maintainability.
• Design and evolve RESTful APIs and service contracts, including resource modeling, error handling, and versioning, in partnership with other engineering teams.
• Integrate with third‑party APIs and internal platforms, handling auth flows, rate limits, and failure modes gracefully.
• Build and maintain dashboards, internal tools, and lightweight customer management systems and configuration tools that give researchers and partner teams powerful, safe controls over customer records, cohorts, and workflows.
• Work effectively within and around existing infrastructure, finding pragmatic solutions and designing extensions that respect current constraints while moving the system forward.
• Read, understand, and refactor existing codebases, improving structure, test coverage, and observability as you go.
• Take ownership of the full lifecycle of your work: technical design, implementation, automated testing, code review, deployment, monitoring, and incident follow‑up.
• Collaborate closely with design, product, research, and other engineering partners to shape requirements, clarify trade‑offs, and deliver high‑quality user and developer experiences.
• Contribute to internal standards and best practices for full‑stack development, API design, and tooling, helping the team move faster and more safely over time.

• 4–7 years of professional software engineering experience, including significant full‑stack work on production systems.
• Strong proficiency with React (or a comparable modern front‑end framework) building modular, component‑based UIs backed by robust state management and testing.
• Hands‑on experience building Node.js services (Type Script or JavaScript), including Express‑style HTTP servers, middle wares, and integrations with downstream services.
• Solid Java programming skills and experience working within existing Java services or microservices (e.g., Spring or similar frameworks).
• Demonstrated experience designing and implementing RESTful APIs, including data modeling, authentication/authorization, and API documentation.
• Experience integrating with third‑party APIs (REST/JSON or similar), including handling retries, backoff, error classification, and observability.
• Comfortable working in and improving existing codebases—including reading unfamiliar code, debugging complex issues, and incrementally refactoring without breaking behavior.
• Familiarity with building dashboards, internal tools, or customer management systems that expose configuration or customer data in safe, user‑friendly ways.
• Proficiency with relational databases (e.g., MySQL, Postgre
  
  SQL) and basic query design; familiarity with at least one No
  
  SQL or document store is a plus.
• Strong foundation in software engineering fundamentals: testing, version control (Git), code reviews, and CI/CD workflows.

• Experience designing or evolving internal platforms or tooling used by multiple teams (e.g., analytics dashboards, experimentation tools, content/experience management, or workflow systems).
• Familiarity with modern front‑end tooling (Webpack/Vite, linting, type‑checking, testing frameworks) and performance optimization techniques.
• Experience working with feature flags, configuration services, or experimentation frameworks.
• Exposure to cloud‑native environments and containerized workloads (e.g., Docker, Kubernetes) and associated observability stacks (logs, metrics, tracing).
• Comfortable navigating ambiguity, breaking down loosely defined problem spaces into clear milestones and shippable slices.
• Strong communication skills with the ability to explain complex technical concepts to non‑technical partners and to write clear technical designs and documentation.
