Crypto • Fintech

Quidax is a crypto exchange and digital asset infrastructure platform built for Africa, enabling individuals, businesses, and institutions to buy, sell, stake, and move stablecoins and other cryptocurrencies. It provides instant swaps, order-book trading, a premium OTC desk, APIs and payment gateway (Basqet) for businesses, a stablecoin API for fiat rails, staking and yield products, a launchpad for token listings, and institutional liquidity and settlement solutions — all with a compliance-focused approach and 24/7 support.

📋 Description

• Join a focused team working on the flows that matter most: deposits, withdrawals, partner integrations, and reconciliation. • Get across the RAMP codebase, understand the core flows, and ship your first meaningful fix in the first 30 days. • Own specific features or flows end-to-end by month 3, with support from the team where needed. • Independently investigate and resolve reliability issues across deposits, withdrawals, and partner callbacks by month 6. • 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. • 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.

🎯 Requirements

• 3 to 5 years of Rails backend experience in production environments. • You write clean code, debug with patience, and care about how your work affects real users. • Comfortable with 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 on-ramp/off-ramp products. • Nice to haves: Familiarity with transaction concepts: idempotency, retries, reconciliation, state machines. • Experience working in a remote startup environment.

🏖️ Benefits

• Fair Pay + Ownership • Competitive salary based on your skills and experience; annual merit-based reviews to keep your growth visible and rewarded • Growth That’s Real • Annual performance reviews + clear promotion cycles; recognition for great work, from shoutouts to milestone rewards • Personal development fund (courses, books, conferences); study leave so you can keep learning • Fully remote forever + flexible working hours • Unlimited paid time off + Nigerian national holidays • Parental, sick, compassionate, and life event leave; we show up for you • Quarterly remote team hangouts + annual offsite; interest-based communities (SIGs) • Regular engagement surveys; your voice matters • Health & life coverage in select locations
