Senior Software Developer
Position Type: Full-Time, Remote
Working Hours: Standard U.S. Business Hours
About the Role
We’re looking for a Senior Software Developer to build and maintain production-grade mobile and backend experiences. You’ll work primarily with React Native, GraphQL, and PostgreSQL, owning features from initial development through deployment and ongoing improvements.
This role is ideal for someone who takes ownership, works independently, and is comfortable solving complex technical problems across the application stack.
What You’ll Own
Mobile Development
- Build, maintain, and improve production React Native applications.
- Own features from scoping and development through deployment and post-launch iteration.
- Work across both iOS and Android applications.
Backend & Data
- Design and maintain PostgreSQL schemas.
- Write efficient queries and optimize database performance.
- Manage indexing, migrations, and data integrity.
- Build and maintain GraphQL APIs, including schemas and resolvers.
- Work with Apollo or similar GraphQL tooling.
Code Quality & Performance
- Participate actively in code reviews and maintain high standards for readability and test coverage.
- Debug issues across the full stack, from React Native performance to PostgreSQL queries.
- Identify technical issues proactively and drive them through to resolution.
Collaboration & Ownership
- Work closely with product, design, and engineering teammates to translate requirements into reliable solutions.
- Communicate progress, blockers, and technical decisions clearly in an async-first environment.
- Contribute to architectural discussions and help identify tradeoffs early.
Requirements
- 5+ years of professional software development experience, including substantial production experience.
- Strong hands-on experience with React Native.
- Experience publishing and maintaining applications on both iOS and Android.
- Strong PostgreSQL experience, including schema design, query optimization, indexing, and migrations.
- Solid experience building and consuming GraphQL APIs.
- Experience with GraphQL schemas, resolvers, and tools such as Apollo or similar.
- Strong debugging and problem-solving skills across the application stack.
- Ability to work independently on ambiguous technical problems.
- Strong written and spoken English for daily collaboration with a distributed team.
What Makes You a Strong Fit
- You take ownership of features from start to finish and care about how they perform in production.
- You proactively identify problems rather than waiting for someone to point them out.
- You communicate clearly and provide enough context for teammates working across different time zones.
- You’re comfortable discussing technical tradeoffs and challenging ideas constructively.
- You care about clean, maintainable code and consistent engineering standards.
- You approach both small fixes and large architectural decisions with attention to quality.
What Success Looks Like
- Features are delivered reliably from development through production.
- React Native applications remain stable, performant, and maintainable across iOS and Android.
- APIs and PostgreSQL queries are efficient and well-structured.
- Technical issues are identified and resolved with minimal back-and-forth.
- Code reviews improve overall quality and maintainability.
- Communication remains clear and proactive across the distributed team.
Typical Day
You’ll spend most of your time writing and reviewing code across the React Native frontend and GraphQL/PostgreSQL backend. You’ll work through tickets, contribute to technical and architectural discussions, collaborate asynchronously with product and engineering teammates, and help ship features to real users.
Because the team works across time zones, strong written communication is an important part of the role. Your updates, documentation, technical decisions, and code reviews will be an important part of how the team works together.
