About
We are looking for an experienced
Full Stack Engineer
who can own features end‑to‑end and make meaningful architectural decisions. The engineering work here is high‑stakes and high‑leverage. You'll build and scale the systems that power credit card issuance, real‑time rewards, and payment processing for our institutional partners – and help mentor more junior engineers along the way.
What You’ll Do
Design, build, and maintain PHP and Python services and RESTful APIs across the full stack, with a focus on scalability, security, and long‑term maintainability
Own features from technical design through deployment – making architectural decisions about data models, API contracts, and system interactions
Work with MySQL, JSON data structures, and third‑party integrations across banking cores and payment networks
Build a deep understanding of our business domain – how credit card programs, rewards, and payment processing work – and use that context to make better engineering decisions
Contribute to technical planning and cross‑functional discussions with product design
Help junior engineers grow through pairing and knowledge sharing
What You’ll Bring
3–5 years of professional development experience, with solid OOP fundamentals
Deep familiarity with RESTful API design, MySQL query optimization, and working with complex data structures
Experience making architectural decisions – not just implementing specs, but designing solutions
Comfort working across the full stack and willingness to pick up whatever technology the problem requires
Ability to work autonomously in a remote, async‑first environment while staying well‑connected to the team
Strong written communication for documentation, technical proposals, sync and async discussion
Comfort with remote‑first, sync and async daily collaboration with fluid times
Bonus if You Have
Experience in fintech, payments, or credit card infrastructure
Familiarity with multi‑tenant platform architecture or real‑time transaction processing
Experience working with LLM APIs or AI‑assisted development tools
Understanding of security and compliance in regulated environments (PCI DSS, SOC2)
What We Offer
Competitive compensation and equity
Remote‑first workplace
Comprehensive health plan and PTO
A team that treats AI as a force multiplier, not a threat
Real ownership – you'll ship code to production and see its direct impact on partners and cardholders
Room to grow into senior and leadership roles as the team scales
