[Hiring] Senior Mobile Developer @Cardata

Role Description

We're hiring a Senior Developer with deep mobile expertise for a small, self-contained innovation group (Initial three-month contract, with opportunity for extension or move to full-time). Working alongside a Product Manager and a web-focused developer, you will:

• Take an ambiguous business problem and turn it into a testable product bet.
• Build the smallest end-to-end experience that can generate meaningful evidence, often in roughly one to two weeks.
• Bring early versions back to customers and the market validation group, gather feedback, and rapidly iterate through V1, V2, V3, and beyond.
• Shift from proving the idea to determining what must change for it to become secure, reliable, scalable, and ready for handoff.

The group operates like an entrepreneurial startup within the larger organization and owns the path from problem discovery through rapid prototyping, customer and market validation, iterative development, and a validated proof of concept.

The operating principle is simple: build to learn first, then build to scale. During validation, speed comes from controlling scope and making deliberate, reversible technical choices—not from designing the final production architecture before the opportunity is proven. Security, privacy, and responsible data handling remain non-negotiable throughout.

Once an idea demonstrates value, you will work with our Core team at key technical integration points to harden, refactor, or redesign what is needed for scale.

Qualifications

• 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.
• 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.

Requirements

• 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.

Benefits

• 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.
