Note: The job is a remote job and is open to candidates in USA. Cardata is hiring a Senior Developer with deep mobile expertise for a small innovation group. The role turns ambiguous business problems into mobile and web prototypes, validates them with customers, iterates on feedback, and prepares successful concepts for secure, scalable handoff to the core team.

Responsibilities

• Work with the Project Lead, Product Manager and Web Developer to turn ambiguous problems into unified driver-and-admin experiences
• Build the smallest end-to-end prototype that can test the idea, often within one to two weeks
• Bring prototypes to customers and the market validation group, then rapidly translate feedback into V2, V3, and beyond
• Challenge assumptions, cut scope, and keep the group moving without waiting for perfect requirements
• Make deliberate, reversible technical choices during validation while protecting security, privacy, and data integrity
• Build within the shared codebase, behind feature flags and in isolated modules that can be removed cleanly
• Integrate with our platform backend and third-party APIs using existing contracts and patterns
• Once a concept is validated, identify and complete the work required to harden, scale, test, and release it
• Prepare validated features and technical context for a clean handoff to the core product and engineering team

Skills

• 6–8 years as a software engineer at a senior level, with a track record of product work at startups and in fast-paced environments
• You've built from nothing, cut scope under time pressure, and shipped
• Comfortable with ambiguity: you can take an unfamiliar domain and an under-specified problem and make progress without waiting to be handed a spec
• Strong product thinker who can connect driver and administrator needs, commercial value, and technical choices across mobile and web
• Strong communicator who identifies gaps, proposes a path forward, and keeps the work moving
• High ownership, sound judgment under time pressure, and a track record of delivering against commitments without hiding material trade-offs
• Comfortable working in a small, autonomous group where priorities can change quickly as new evidence emerges
• Very comfortable with React Native, plus native iOS (Swift) and Android (Kotlin) development
• Familiar with the full mobile release process for both iOS and Android, including store submission and review
• Solid integrating against REST / backend APIs and handling auth, tokens, and SSO on device
• Comfortable collaborating across mobile, web, and backend boundaries to create one coherent product experience
• You adopt the existing patterns and conventions of the mobile codebase rather than introducing your own
• You know how to code and understand good software design. You are not strictly a "vibe coder": you can reason about architecture and trade-offs, not just prompt your way to output
• You've adopted modern AI development workflows and use tools like Cursor, Claude Code, or Copilot as part of how you ship
• You understand AI skills, agents, and code-spec workflows, and how to use them without losing engineering rigour
• You lean on AI to move faster on prototypes and to hold quality up during hardening
• Ability to flex onto the Portal stack (TypeScript / Next.js / NestJS / PostgreSQL) when a bet calls for it

Benefits

• Remote work and flexible working hours
• Mentorship and development opportunities
• Extended medical & dental benefits
• Healthcare spending account
• $3,000 annual Health and Wellness Spending Account to support your overall wellbeing
• Employee assistance program (EAP)
• Flexible (Unlimited) Time Off: No annual cap on vacation, supported by a trust-based, flexible approach to time away.
