Full job description

Senior Software Engineer (C# .NET)

Payments & Financial Infrastructure (Remote)

A fast-scaling global payments infrastructure company is building the financial rails that move real money across borders at speed, at scale, and with zero tolerance for failure. The platform powers cross-border transactions for SMEs and enterprises using a blend of traditional banking networks and stablecoin-backed blockchain rails . Transaction sizes are meaningful. The systems are live. The consequences are real.

The engineering team is distributed, lean, and fast-moving . Decisions are made quickly. Priorities shift. External partners change things without warning. The expectation is simple: build systems that hold up in the real world .

This is not a “feature factory” role.
This is financial infrastructure .

They are now hiring a Senior Software Engineer (C# .NET) to play a key role in shaping and stabilising their backend payments platform.

The Role (What You’re Really Signing Up For)

As a Senior Software Engineer, you’ll own and evolve critical backend services that sit directly in the path of money movement.

You’ll:

Design and build API-driven services that process real payments
Integrate with banks, payment providers, identity platforms, and blockchain rails
Balance speed vs safety , often with incomplete information
Take responsibility when things go wrong not just when they go right

This role suits someone who has already worked in regulated, high-risk systems and understands that elegance matters less than reliability.

What You’ll Be Doing

Backend & API Engineering

Design and build secure, scalable APIs in .NET 8 / C#, powering payment and stablecoin transactions
Own backend services end-to-end — from design through production support
Build background processing, scheduled jobs, and webhook-driven workflows
Integrate with third-party payment, banking, KYC and identity providers

Payments, Crypto & Real-World Complexity

Implement logic that touches real money , not test data
Build and maintain integrations across traditional rails and blockchain-backed stablecoin flows
Create mock services and defensive layers for partners without stable test environments
Design systems that expect breaking changes outside your control

Security, Risk & Compliance (By Design)

Implement secure API patterns: authentication, encryption, auditing and monitoring
Treat financial data with the caution it deserves
Build systems that work within regulatory and compliance constraints rather than fighting them

Cloud, Infrastructure & Reliability

Deploy and operate services on AWS (Lambda, EC2, DynamoDB, S3)
Collaborate closely with DevOps on CI/CD pipelines (GitHub Actions)
Build containerised services (Docker) designed for scalability and resilience
Monitor production systems using tools like DataDog , catching issues early

Team & Ways of Working

Work closely with product and engineering to convert evolving requirements into stable systems
Review code, raise the bar, and challenge risky assumptions
Be comfortable with context-switching between BAU stabilisation and new feature work
Communicate clearly in a fully remote, distributed team

The Technical Stack

Backend: .NET 8, C#, EF Core, Hangfire, RestEase, NUnit
Data: PostgreSQL, DynamoDB
Infrastructure: AWS, Docker, GitHub Actions
Auth & Observability: Auth0, DataDog
Domain: Payments, identity verification, banking partners, stablecoin rails

Who This Role Is Really For

You’ll Likely Thrive If You:

Have 5+ years of building production backend systems in C# .NET
Have worked in fintech, banking, payments, or regulated environments
Understand that money is risk , not just data
Are calm under pressure and methodical when things break
Can operate without perfect specs or stable third parties
Take ownership instead of waiting for instructions
Prefer reliability and clarity over shiny greenfield builds

This Role Is Probably Not for You If You:

Need everything fully specified before you start
Prefer slow, linear delivery cycles
Avoid BAU, optimisation, or legacy improvement work
Get frustrated by external dependencies you don’t control
Are uncomfortable dealing with production responsibility

(Both kinds of engineers are good — just not for this role.)

Nice-to-Haves (Not Deal Breakers)

Experience with blockchain or stablecoin-based payment flows
Hands-on use of DataDog for logs, metrics, and alerting
Familiarity with Auth0 or similar auth providers
Experience building integration-heavy systems with multiple external APIs
Exposure to financial compliance or regulated domains

What Makes This Worthwhile

Real ownership: You’ll work on systems that matter, not internal tooling nobody uses
High impact: Your decisions directly affect real-world payments and customers
Fast growth: Early-stage scale means fast learning and expanding responsibility
Distributed team: Remote-first, pragmatic, outcome-focused
Meaningful work: You’re enabling faster, more accessible financial infrastructure globally

Final Note

This environment rewards engineers who are:

Thoughtful
Cautious
Accountable
Comfortable with ambiguity

It is not about being the loudest or fastest,

It’s about building systems that don’t break when it matters most .
