Software Engineer (Ruby, Ruby on Rails)
Quidax - Remote
About the Role
- We're hiring a Mid-Level Rails Engineer to work on RAMP, our on-ramp/off-ramp product that helps users move money in and out of crypto.
- You'll join a focused team working on the flows that matter most: deposits, withdrawals, partner integrations, and reconciliation.
- 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 & Contribute:
- First 30 days: Get across the RAMP codebase, understand the core flows, and ship your first meaningful fix.
- By month 3: Own specific features or flows end to end, with support from the team where needed.
- By month 6: Independently investigate and resolve reliability issues across deposits, withdrawals, and partner callbacks.
Reliability & 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 & 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 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.
- Any exposure to crypto exchanges, payment providers, or bank integrations.
Reporting Line:
- You'll report to the RAMP Engineering Manager and work closely with the RAMP Product Manager on priorities, user problems, and what gets built next.
- Day to day, you'll collaborate with design, compliance, operations, support, and finance, as well as external partners.
