You will be expected to design systems, make architectural decisions, and take full ownership of code quality while leveraging AI tools to deliver high-quality, maintainable, and well-reasoned solutions. The position combines mobile systems, backend services, and research oriented programming, working closely with product, operations, and research stakeholders.
Key Responsibilities
- Design and develop end-to-end systems across mobile applications (iOS & Android), backend services, APIs, and data layers
- Take ownership of system architecture, including component boundaries, data flow, and client–server responsibilities
- Collaborate with cross-functional teams to translate real-world operational and research requirements into scalable technical solutions
- Build and maintain backend services and integrations supporting LocoBike’s core mobility and operations platforms
- Work closely with mobile apps, understanding performance, latency, reliability, and real-world usage constraints
- Use Python to support R&D activities, including:
- Data processing and analysis
- Algorithm prototyping and experimentation
- Supporting research validation and technical documentation
- Leverage AI coding agents to accelerate development while:
- Clearly defining problems and constraints
- Critically reviewing and validating generated code
- Ensuring correctness, performance, and maintainability
- Review AI-assisted outputs with a strong verification mindset, considering edge cases, failure modes, and long-term implications
- Continuously improve system design, code quality, and development workflows

- Experience designing and consuming RESTful APIs and working with databases
- Familiarity with AI coding agents and a demonstrated ability to:
- Frame problems clearly before generating code
- Evaluate, refine, and take ownership of AI-assisted outputs
- Use AI to improve quality, not just speed
