What you'll do:

What you'll bring:

Qualifications

• Core Experience
• 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
• Technical
• 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
• AI-Native Mindset
• 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
• We’ll be honest — Cardata isn’t for everyone. If you thrive in a fast-paced environment, take extreme ownership, and constantly push yourself (and your work) to be the best, you’ll fit right in.
• You’ll be surrounded by driven teammates who genuinely care — about the work, about our customers, and about helping each other succeed. Together, we take on ambitious goals and celebrate the wins along the way.
• Remote work and flexible working hours
• Mentorship and development opportunities (to help you achieve your career goals!)
• 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.
• Cardata is an equal opportunity employer. All candidates will be equally considered without regard to race, ancestry, place of origin, colour, ethnic origin, language, citizenship, creed, religion, gender/gender identity, sexual orientation, age, marital status, physical and/or mental handicap or financial ability. We are dedicated to creating an inclusive environment where everyone feels welcome to bring their authentic selves to work.

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
