Backend Software Engineer

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.
