Senior Full Stack Engineer

• 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
• 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

Benefits

• Work from home opportunities
• Health insurance

• Willingness to take on hard, ambiguous challenges, break them down into tractable pieces, and lead others through uncertainty
• Proven ability to deliver high-quality features and platform improvements under aggressive schedules while maintaining sound engineering judgment
• Ability to operate in evolving codebases and systems: you’re comfortable when migrations, new features, and reliability work are all happening at once
• Clear, structured communication skills — you can explain tradeoffs to product and design, collaborate with firmware and hardware teams, and keep stakeholders aligned as plans evolve
• Strong learning and growth mindset — you are continuously sharpening your skills across the stack (frontend, backend, cloud, IoT) and stay curious about new approaches
• Strong ownership mindset — you take responsibility for outcomes across the stack, from UX and APIs to data models and infrastructure, and you close loops without being asked
• Resilience and comfort with failure — you experiment, learn quickly from what doesn’t work, and turn those lessons into better designs and systems
• BS/MS in Computer Science, Engineering, et al. or a great portfolio of web-based applications
• Track record of effective cross-functional collaboration, including refining requirements, giving constructive feedback, and representing engineering in roadmap discussions
• Strong mentoring instincts — you help other engineers grow by sharing context, reviewing designs and code thoughtfully, and modeling calm under pressure
• Bias toward action — you move work forward, unblock others, and make pragmatic decisions with incomplete information while still raising quality over time
