Senior Backend Engineer - Payments

Location: Bangalore, KA

Employment type: Full-time

We’re building the system of record for how money moves through our platform: a double-entry, auditable payment ledger that powers charges, refunds, payouts, fees, and reconciliations. If you love correctness, clean data models, and high-throughput systems, you’ll own one of the most critical pieces of our product.

What you’ll do

• Design & build the ledger : Append-only journal + accounts with double- entry guarantees; immutable records with corrections via compensating entries; enforce invariants (debits = credits) at the schema and application layers.

• Get consistency right : Choose isolation levels, implement idempotency, and design APIs that are safe under retries and partial failures.

• Own reconciliation : Build daily/continuous reconciliation pipelines against payment processors and bank statements; surface diffs, exceptions, and workflows to resolve breaks.

• Model money flows : Support holds, captures, refunds, chargebacks, fees, partner revenue share, and multi-currency/FX with correct rounding and rate provenance.

• Integrate processors : Ship robust integrations with webhooks, signature verification, event ordering, and replay handling.

• Observability & audit : Comprehensive audit logs, traceability from external events → ledger entries → financial reporting; metrics, SLOs, and alerting for breaks or stuck money.

What makes you a great fit

Must-haves

• 5–7 years building backend systems in Node.js, NestJS, JavaScript, TypeScript.

• Deep experience with relational databases (PostgreSQL/MySQL), transactions, schema design, migrations, and query performance.

• Proven track record designing idempotent APIs, background jobs, and event processing at scale.

• Solid grasp of accounting basics (double-entry, journals vs. ledgers, trial balance) or strong interest to learn quickly.• Strong testing discipline: property tests, fixtures, deterministic replay; comfort with production-grade observability.

• Clear communication, product sense, and ownership from design to post-launch ops.

Nice-to-haves

• Built payments/fintech/marketplace systems: payouts, split payments, escrow, invoices or wallet/accounting.

• Experience with event sourcing, CDC, Kafka/PubSub, or stream processing.

• Multi-currency/FX flows and rounding modes; localized taxes/fees.

• Hands-on with Stripe/Adyen/Braintree/Razorpay/PayU, bank files (MT940/BAI2), or virtual accounts.

• Familiarity with compliance/audit (SOX controls, PCI DSS scope reduction) and data retention policies.

• Kubernetes/cloud infra (GCP/AWS) and secrets management.
