Senior Software Engineer

5+ years of experience as a software engineer on SaaS or customer-facing products, including leading delivery of complex, large-scale features.

Strong TypeScript and modern React (hooks, React 18, Vite or similar tooling), with an eye for performant, accessible UI.

Production experience with Node.js and/or Go on the backend -- including concurrency, service-to-service communication, and asynchronous/background processing -- and willingness to work in both.

Experience designing APIs (REST and/or gRPC) for high-throughput systems, including versioning, validation, and documentation.

Solid SQL proficiency (MySQL or PostgreSQL) with schema design and query optimization experience; familiarity with document stores like MongoDB.

Familiarity with caching strategies (Redis/Redis Cluster) and event/queue systems (Kafka, SQS/SNS, or Pub/Sub).

Experience building or operating real-time features (WebSockets, SSE, or Firebase-style realtime databases) at meaningful scale.

Working knowledge of cloud infrastructure -- AWS and/or GCP -- plus Docker and an orchestration platform (ECS or Kubernetes); comfort with infrastructure-as-code (Terraform or Helm).

A habit of writing tested code (Vitest, Jest, React Testing Library, or Go testing/testify) and improving test coverage where it’s thin.

Comfort navigating large existing codebases -- including legacy code mid-migration -- and complex local dev environments (Docker Compose, monorepos, generated code).

Strong written communication and proactive collaboration habits suited to a distributed team with US time-zone overlap.

Track record of delivering performant, scalable features, advocating for engineering quality, and mentoring teammates.

A genuine interest in impacting the world of education.

Experience integrating LLM APIs (OpenAI, Gemini) into production features, including prompt design, streaming, moderation, and cost/quota controls.

Experience with Elasticsearch or other search/indexing systems.

EdTech domain exposure: LTI, Google Classroom, OneRoster/Clever rostering, or student data privacy practices.

Browser extension, Google Apps Script/Workspace add-on, or Office add-in development.

Canvas/animation work (Konva, Spine, Rive, Lottie) or rich-text editing (Slate, MDX).

Accessibility (WCAG, axe-core) and internationalization (i18next) experience.

Observability depth: OpenTelemetry instrumentation, Prometheus metrics, or Datadog dashboards.
