Backend Software Engineer

About this role

ABOUT THE ROLE

We're a small, cross-functional engineering team building cloud services that power a fleet of enterprise-deployed Android devices. As a Backend Software Engineer, you'll own core infrastructure — from scaling and reliability to over-the-air (OTA) update pipelines — that makes mobile products usable at enterprise scale. You'll work across the full product surface, translating real customer requirements into production-ready, reusable solutions.

This is a high-ownership role on a tight-knit team. You'll write design docs, lead reviews, shape development practices, and ship code that matters.

WHAT YOU'LL DO

- Build and maintain backend services supporting a Mobile Infrastructure as a Service platform.

- Work across the stack — from Android OS and apps to CLI tools, dashboards, and provisioning automation.

- Architect web services to meet demanding scale and reliability requirements.

- Enhance and operate core over-the-air (OTA) update infrastructure.

- Design and implement authorization and security models for web services.

- Translate customer-specific requirements into generic, reusable backend solutions.

- Architect and build new web services and internal tooling.

- Write design one-pagers and lead design reviews with the team.

- Conduct peer code reviews and help shape team development standards.

- Build and maintain test automation and CI/build management pipelines.

- Drive new product development and write public-facing API and feature documentation.

- Collaborate with international teammates and contribute to DevOps efforts as needed.

WHAT WE'RE LOOKING FOR

Required

- 3+ years of software development experience, with 2+ years focused on cloud and backend systems.

- Strong experience designing and implementing RESTful APIs and web services.

- Demonstrated experience scaling web services in production environments.

- Hands-on experience with AWS (or comparable cloud platforms such as GCP or Heroku).

- Proficiency in at least one backend programming language/stack (e.g., Java, Python, or Node.js).

- Experience with testing and test automation.

- Strong CS fundamentals or equivalent professional experience.

- Bachelor's degree in Computer Science or a related field, or equivalent experience.

- Authorized to work in the United States (US citizen or valid US work visa). Visa sponsorship is not available.

- Based in or willing to work on-site in Seattle, WA.

Nice to Have

- Familiarity with server-side JavaScript / Node.js and the Express framework.

- Experience with JavaScript ES6+ testing frameworks (e.g., Mocha, Chai, Sinon).

- Exposure to front-end JavaScript frameworks such as React.

- Knowledge of the Android ecosystem, APIs, and development tools.

- DevOps / configuration management experience (e.g., Ansible or similar).

- Practical knowledge of Git and CI/build tooling.

Who thrives here: Engineers who are curious, collaborative, and comfortable owning problems end-to-end — from architecture through documentation. You communicate clearly, stay humble, and care about building things that work reliably at scale.

COMPENSATION & BENEFITS

- Salary: $100,000 – $150,000 USD annually, depending on experience.

- Opportunity to have a significant impact on core infrastructure at an early-stage company.

- Small, collaborative team with a strong engineering culture.

LOCATION

This is an on-site role based in Seattle, WA, USA. Candidates must be located in Seattle or willing to relocate. Visa sponsorship is not available — applicants must be authorized to work in the United States.
