About Quidax
Quidax is where money meets limitless possibilities. We’re making it super easy for individuals, businesses, and fintechs in Africa to access crypto. Our goal? Providing real value for our customers today while shaping the future of money.
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.
Reporting Line
You'll report to the Engineering Manager and work closely with senior engineers, product managers, and mobile and frontend teammates to build and strengthen the core of our backend infrastructure.
