Job description

About 1Money

1Money is a fast-growing global fintech building the world's first full-stack stablecoin payments infrastructure. Our mission is to enable frictionless, ultra-low-cost global money movement — built to the standards expected of financial infrastructure: correctness, security, compliance, reliability, and operational discipline.

• Backed by top-tier global investors including Fidelity (F-Prime), Galaxy Ventures, Portage, Hack VC, and Tribe Capital.
• Our team brings experience from world-leading organizations such as Binance, Ripple, Circle, Uber, Goldman Sachs, Ant Financial, and OKX.

What we build:

• 1Money Network: a Layer-1 purpose-built for stablecoin payments — designed to be the cheapest, fastest, and most compliant.
• 1Money.com: a fully licensed stablecoin orchestration platform offering on/off ramps, exchange, transfer, and custody.
• 1Money Issuance Platform: end-to-end infrastructure for businesses to issue and scale their own stablecoins.

Role Overview

We are hiring a senior backend engineer in India to build and scaleglobal fiat connectivityfor 1Money. This role focuses first on integrating banks, payment providers, local payment rails, liquidity partners, and compliance/risk vendors across markets. Over time, it may expand into adjacent domains such as trading, treasury, account onboarding, auth, stablecoin issuance, and core platform architecture.

You will design APIs, vendor adapters, payment workflows, reconciliation flows, asynchronous jobs, and operational tooling supporting fiat pay-ins, payouts, prefunding, settlement, transaction monitoring, and partner integrations. India's timezone is strategic — it gives usfollow-the-sun coveragefor global banking partners across Asia, EMEA, and the Americas.

The right person isnot just a feature implementer. We are looking for an engineer who can reason about distributed systems, financial state transitions, idempotency, retries, observability, data integrity, and production incidents.

What You Will Work On

Global Fiat Connectivity

• Build and own integrations with banks, payment processors, local payment rails, liquidity providers, and vendor APIs.
• Design reliable pay-in and payout workflows across multiple jurisdictions and currencies.
• Implement vendor adapters, routing logic, webhook handlers, reconciliation jobs, and operational dashboards.
• Handle real-world payment edge cases: delayed confirmations, duplicate webhooks, partial failures, returned payments, provider downtime, inconsistent vendor statuses, and compliance holds.
• Partner with product, operations, compliance, and banking partners to turn business and regulatory requirements into robust technical systems.
• Build high-quality backend services and modules in Rust, with strong attention to safety, performance, maintainability, and correctness.
• Design REST APIs, internal service interfaces, webhooks, async jobs, and event-driven workflows.
• Work with MySQL/PostgreSQL, Redis, queues/messaging systems, and cloud infrastructure.
• Improve reliability through idempotency, retries, dead-letter handling, observability, structured logging, tracing, metrics, alerting, and runbooks.
• Make practical architecture trade-offs across speed, reliability, operational cost, compliance, and long-term maintainability.

High-Correctness Financial Infrastructure

• Work on transaction routing, settlement, balances, reconciliation, transaction monitoring, and operational controls.
• Protect data integrity across asynchronous workflows and vendor-driven state changes.
• Build systems that are auditable, observable, and safe to operate in a regulated fintech environment.
• Write and review Tech Designs for cross-domain or high-risk changes before implementation.
• Use AI development tools (e.g. Claude, ChatGPT, Cursor, Copilot) to improve development speed and code-review quality.
• Apply AI tools responsibly within the security, data-handling, and compliance constraints of a regulated financial institution.
• Improve team workflows, documentation, test generation, debugging, and operational analysis using AI-assisted methods — without outsourcing engineering judgment.

What We Are Looking For

Required

• 5+ years of professional backend or platform engineering experience, with a track record of owning critical systems in production.
• Ruststrongly preferred. Strong engineers inothersystems/backendlanguages(Go, Java, C++) without deep Rust experience are welcome, provided they can become productive in Rust quickly — our core platform is Rust.
• Strong CS fundamentals: data structures, algorithms, networking, operating systems, concurrency, and distributed systems.
• Experience designing and operating production backend systems with databases, caches, async processing, queues, and external APIs.
• Practical experience with API design, idempotency, retries, error handling, observability, and debugging production issues.
• Strong SQL skills and experience designing data models for correctness, auditability, and operational use.
• Clear written communication and the ability to work across time zones with engineers, product, compliance, and operations.
• Ownership mindset — able to take an ambiguous integration or system problem from design through production support.

Strongly Preferred

• Experience in payments, fintech, banking integrations, FX, trading, treasury, reconciliation, ledger/balance systems, or regulated financial infrastructure.
• Experience integrating third-party vendors or financial partners where API behavior, webhooks, and operational edge cases are imperfect.
• Production Rust, especially async Rust, Axum, SeaORM/sqlx, Tokio, or similar backend stacks.
• Event/messaging infrastructure: Kafka, SQS/SNS, NATS, or RabbitMQ.
• AWS/GCP/Azure, Docker, Kubernetes, CI/CD, and production observability tooling.
• Exposure to stablecoins, digital assets, wallets, custody, on-chain payments, or blockchain infrastructure.

Education & Background

• Bachelor's degree or higher in Computer Science, Software Engineering, Mathematics, Electrical Engineering, or a related technical field — or equivalent practical experience.
• We value strong engineering fundamentals and evidence of high judgment. Candidates fromIITs, IISc, IIIT-Hyderabad, BITS, top NITs, and comparable global universitiesare encouraged to apply — but school brand is not a substitute for demonstrated engineering quality.
• Experience at high-performance engineering organizations in fintech, payments, banking, crypto, cloud infrastructure, e-commerce, consumer tech, or enterprise platforms is highly relevant.

What Success Looks Like

First 3 months:understand the 1Money platform, ship scoped backend changes, contribute to one or more fiat connectivity integrations, and participate effectively in technical design and code review.

First 6 months:own a meaningful integration or subsystem end-to-end — API design, vendor behavior, persistence, async jobs, observability, incident handling, documentation, and operational handoff.

Over time:become a key India-based owner for global fiat connectivity, with the ability to expand into other high-impact backend domains as the team scales.

How We Work

• We build financial infrastructure where correctness matters.
• We prefer clear domain ownership, strong technical design, and pragmatic implementation over architecture theater.
• We use AI tools to move faster, but we do not outsource engineering judgment.
• We work across regions and time zones — written communication, ownership, documentation, and operational clarity matter.
• We expect engineers to care about production behavior, not only code delivery.

Async Rust (Axum, SeaORM, Tokio) · MySQL · Redis · event-driven services (Kafka / SQS) · AWS · Docker. You will work in a Rust-first backend codebase serving regulated, money-movement workloads.

Location & Reporting

• Location:India (Remote), with Bengaluru preferred where possible.
• Reports to:Engineering Leadership.
• Collaboration:close overlap with our Asia/UAE, Brazil, and US teams for global engineering coverage.

We are committed to building a diverse and inclusive workplace. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.
