Ruby On Rails Developer

3.4.7

What You’ll Do

• Own Stripe Connect flows end-to-end:

  onboard/verify accounts, compute fees/transfers, schedule/retry payouts, reconcile ledger vs. Stripe, and tame webhooks with strict idempotency and audit trails.

• Harden withdrawals, subscriptions, and pledge fulfillment:

  integrate ML risk scores, design review queues/escalations, reduce false positives/chargebacks while protecting organizers and buyers.

• Build internal/admin tooling that unblocks Support & Compliance:

  dispute evidence packs, refunds/partial refunds, adjustments, KYC/KYB timelines, and traceable actions, safe by default.

• Advance the monolith thoughtfully:

  service objects, shared domain gem boundaries, JSONB access patterns, zero-downtime migrations, and clear logging/observability aligned with our conventions.

• Push the data layer under load:

  author/tune complex SQL, choose locks/isolation deliberately, eliminate deadlocks/races, partition/archive hot tables, and prove correctness with boundary/transaction tests.

• Run Sidekiq Pro at scale:

  design idempotent pipelines, sane backoff/retry/DLQ strategies, cron/batch orchestration, and instrumentation that turns incidents into measurable reliability gains, reviewing and being reviewed to our testing standards.

What We’re Looking For

• 8+ years building large, complex applications;

  5+ years hands-on Ruby/Rails

  moving real money.
• Deep payments experience (Stripe Connect or similar): webhooks, reconciliation, refunds, disputes, payout timing, rate limits.
  
• PostgreSQL expertise: query plans, row/statement locks, isolation levels, race analysis; strong

  JSONB

  patterns.
• Redis +

  Sidekiq Pro

  at meaningful scale: throughput tuning, idempotency, retries, DLQs, observability.
• Testing craft: one-assertion tests, minimal mocking, boundary/transaction isolation, comprehensive error handling.
  
• Security/compliance mindset: PCI-aware design, audit logging, least privilege, secure defaults.
  
• AI-augmented workflow (Copilot/ChatGPT/Claude) for exploration, scaffolding, and tests, paired with rigorous code ownership.
  
• Clear communicator who writes crisp docs, reviews PRs thoughtfully, and explains trade-offs to partners.
  

Why This Role Is Different

• Mature monolith, not microservice sprawl:

  a well-architected Rails codebase (API + Admin + shared domain gem) with conventions, tests, so you spend time engineering, not guessing.

• Serious domain, real impact:

  complex financial flows, fraud controls, and correctness that matters, creativity inside constraints.

• Testing and documentation as accelerants:

  our standards enable speed without regressions; you’ll help evolve them.

• AI-forward culture:

  use AI for leverage; keep judgment, security, and correctness as the bar.
