Senior Full Stack Engineer

About the role

Owl Labs is looking for a Senior Full Stack Engineer to build customer-facing product experiences and the backend systems that support them. You’ll work across frontend, backend, cloud infrastructure, and device-connected workflows, partnering cross-functionally to ship high-quality software in an evolving, fast-paced environment.

WHAT YOU'LL DO:

- Build and ship customer-facing features across the Owl Labs customer portal — a React + Vite SPA used daily by customers to manage their devices.

- Drive and contribute to active codebase migrations (i.e. JavaScript → TypeScript) to improve reliability, safety, and long-term maintainability.

- Own performance work: identify and fix bottlenecks through virtualization, memoization, code splitting, and bundle optimization.

- Work within and occasionally extend our shared design system, contributing reusable components and UX improvements.

- Write unit tests as a standard part of every change and contribute to our Playwright e2e suite to keep the portal stable as it evolves.

- Design, build, and operate backend services on AWS (Lambda, ECS, API Gateway, S3, IAM) that power the customer portal and device management workflows.

- Model and query data across PostgreSQL and DynamoDB, choosing the right store for the job and optimizing indexes, access patterns, and query performance.

- Implement IoT communication flows using MQTT and WebSockets, integrating with AWS IoT Core and other messaging services to manage fleets of connected devices.

- Build decoupled, event-driven systems using queues and event buses (SQS, SNS, EventBridge) to keep the platform scalable and resilient under load.

- Ship and iterate on RESTful APIs and WebSocket endpoints consumed by frontends and edge devices, with careful attention to versioning, latency, and reliability.

- Instrument services with logging, metrics, and tracing (CloudWatch, X-Ray, Honeycomb or equivalents) to quickly debug and triage production issues.

- Use feature flags to release changes safely, run experiments, and coordinate complex migrations across frontend and backend surfaces.

- Define and maintain BDD/E2E test suites (Playwright, Cypress) that validate behavior end-to-end across web, APIs, and device interactions.

- Own and improve CI/CD pipelines (e.g., Bitbucket) so deployments are predictable, repeatable, and easy to roll back when needed.

- Proactively leverage AI tools (e.g., Claude, Codex) to accelerate development, automate repetitive tasks, and keep documentation, tests, and infra configuration up to date.

- Collaborate with product, design, and hardware/firmware teams, contributing technical insight into roadmap discussions for SaaS and IoT features.

WHAT WE'RE LOOKING FOR:

- BS/MS in Computer Science, Engineering, et al. or a great portfolio of web-based applications.

- Strong learning and growth mindset — you are continuously sharpening your skills across the stack (frontend, backend, cloud, IoT) and stay curious about new approaches.
