Fresh Jobs at Quidax

About the Role

• You own the end-to-end user experience for a specific product pillar. You are the day-to-day champion for the user, working in a "squad" alongside Product Managers and Engineers.

What You’ll Be Owning

• End-to-End Pillar UX: Designing full user journeys, wireframes, and high-fidelity interfaces for your dedicated product area (e.g., Payments, Onboarding).
• Tactical User Research: Planning, executing, and synthesizing usability studies and user interviews to validate your specific feature designs.
• Handoff & Implementation QA: Creating detailed developer handoff files and performing "design QA" on builds to ensure the final product matches the intent.
• Design System Contribution: Actively identifying gaps in our component library and proposing new patterns to the Design System Lead.

What We’re Looking For

• Problem Solver: You start with the user problem, not the solution, and can iterate quickly through wireframes to find the best flow.
• Visual Executor: You have a high bar for UI design and can deliver polished, high-fidelity designs that are ready for production.
• User Advocate: You are comfortable running your own usability tests and using that feedback to kill your "darlings" for the sake of the user.
• Autonomous Worker: You thrive in a squad environment and can manage your own time and priorities alongside a Product Manager.

​​​​​​About the Role

• We're hiring a Mid-Level Java, Spring Boot Engineer to work on the core backend systems that power how customers trade, move money, and interact with the Quidax platform. You'll join a team working on the flows that matter most: APIs, integrations, transaction processing, and the reliability of systems that real customers depend on every day. It's a great role for an engineer who's ready to go deeper, take real ownership, and grow fast in a fintech environment.

What You’ll Be Owning

Learn and Contribute

• First 30 days: Get across the core Java/Spring Boot services, understand the critical flows, and ship your first meaningful fix.
• By month 3: Own specific features or services end to end, with support from the team where needed.
• By month 6: Independently investigate and resolve reliability issues across APIs, integrations, and transaction flows.

Reliability and Code Quality

• Reduce recurring issues: stuck transactions, failed callbacks, unclear states, and manual escalations.
• Improve test coverage across critical flows and leave every area you touch cleaner than you found it.
• Add observability where it's weak: better logging, alerts, and debugging hooks.

Team and Growth

• Participate in code reviews, share what you learn, and support engineers around you.
• Grow your understanding of transaction heavy systems: idempotency, retries, state machines, and reconciliation.

Biggest Challenges You’ll Tackle

• Working on backend systems where failures have real customer impact.
• Debugging complex, transaction heavy flows that aren't always well documented.
• Balancing new feature work with improving the stability of existing systems.
• Learning fintech and crypto infrastructure concepts on the job and applying them quickly.

What We’re Looking For

Must-haves

• 3 to 5 years of Java Spring Boot backend experience in production environments.
• You write clean code, debug with patience, and care about how your work affects real users.
• Comfortable with REST APIs, background jobs, database design, testing, and debugging.
• Methodical debugger: you trace flows, read logs, and find the real root cause.
• You improve code incrementally without defaulting to a full rewrite.
• Bonus: Experience in fintech, payments, crypto, or transaction heavy backend systems.

Nice to Haves

• Familiarity with transaction concepts: idempotency, retries, reconciliation, state machines.
• Experience working in a remote startup environment.
• Any exposure to crypto exchanges, payment providers, bank integrations, or Java ecosystem tools like Kafka, JPA, or Hibernate.
