Role summary

DistantJob is seeking a Senior .NET Integration Engineer for a fintech client that automates accounts payable, payments, and financial operations. The role focuses on designing, building, and owning the integration layer that connects the platform to ERP and accounting systems. Responsibilities include developing REST and SOAP integrations, managing data synchronization and reconciliation, ensuring reliability, and contributing to engineering standards. The company is adopting AI-assisted development tools. This is a fully remote, full-time, long-term position requiring 5+ years of software engineering experience with C#/.NET, strong SQL Server skills, and experience with data synchronization and event-driven architectures.

There are only two hard problems in computer science: cache invalidation, naming things, and convincing an ERP that "Acme Corp." and "ACME Corporation" are the same vendor.

If that joke hurt a little, keep reading.

DistantJob is looking for a Senior .NET Integration Engineer to join one of our clients, a fintech company whose platform automates accounts payable, payments and financial operations for investment firms, family offices and fund administrators. Their customers rely on the platform to connect with the accounting systems they already use, so the integration layer is central to the product.

The role

You'll design, build and own the integrations that link the platform to ERP and accounting systems such as NetSuite, QuickBooks, Sage and Microsoft Dynamics. You'll work closely with a Staff Engineer and take real ownership, from scoping through production. You'll spend your time on:

Building and improving REST and SOAP integrations that hold up against messy real-world customer setups

Designing sync, mapping, validation and reconciliation workflows that keep data accurate between systems

Handling partial failures, retries and eventual consistency, with idempotency and audit trails built in

Improving performance and reliability, adding logging and alerting, and finding the root cause when an integration breaks

Working with the onboarding and support teams to get customers connected and live

Contributing to code reviews, documentation and engineering standards

This team is also actively adopting AI-assisted development with tools like Cursor, Claude Code and GitHub Copilot, so you'll have room to work that way.

What we're looking for

5+ years of software engineering with production systems

Strong C# and .NET, including backend services and APIs

Proven experience integrating with ERP, accounting or financial systems

Solid knowledge of REST and SOAP, including authentication, error handling, retries and versioning

Experience with data synchronization, transformation and reconciliation

Strong SQL Server skills: query design, optimization and data modeling

Experience with event-driven or message-based architectures

Independence and clear communication with both engineers and non-technical stakeholders

Bonus points for:

Hands-on NetSuite, QuickBooks, Sage or Dynamics integration work

A background in fintech, payments, AP or fund administration

Azure experience (Service Bus, Functions, API Management)

SFTP, EDI or file-based integration patterns

Python for scripting and tooling

Multi-tenant SaaS experience

Observability practices such as structured logging and tracing

Daily use of AI coding tools

Details

Location: Fully remote

Schedule: US business hours, Central time preferred but can work in Eastern time

Type: Full-time and long-term

Time off: 10 paid vacation days and 8 paid national holidays per year

Why this one?

You'll own the integration layer of a growing platform, not just pick tickets off a backlog. The team collaborates closely, and the company is serious about its engineering standards.
