Lead Software Engineer

Help Rebuild a Multi-Trillion Dollar Industry Through Software

We're partnered with one of the most exciting venture-backed technology companies in the US, building a modern software platform that is transforming how financial products are originated, processed and delivered.

Operating within a market worth trillions of dollars annually, the business is replacing traditionally manual, people-intensive processes with intelligent software and automation. Their platform enables organisations to launch, scale and operate complex financial services far more efficiently than ever before.

Following significant growth and continued investment, the engineering team is expanding rapidly and looking for talented Back End Engineers to help build the integrations that power an entire industry ecosystem.

The Opportunity

As a Back End Engineer within the Integrations team, you'll be responsible for building and maintaining the critical connections between the platform and a wide range of external partners.

These integrations form the backbone of the product, enabling the seamless flow of data and services between multiple organisations, systems and providers. You'll own solutions from initial design through deployment, monitoring and long-term maintenance.

This is a highly autonomous role where you'll have the opportunity to make a visible impact from day one.

• Building and maintaining integrations with third-party platforms and service providers
• Designing scalable, reliable solutions across REST, SOAP and file-based interfaces

• Working closely with Product and Engineering teams to understand business requirements and deliver robust technical solutions
• Identifying opportunities to improve performance, reliability and scalability across integration services
• Managing multiple priorities and partner relationships simultaneously
• Shipping new capabilities that unlock meaningful value for customers

Technology Environment

You'll primarily be working within a modern TypeScript ecosystem and will gain exposure to a range of technologies including:

• TypeScript
• Node.js
• NestJS
• GraphQL
• Temporal.io
• Modern API architectures
• Distributed systems and workflow automation

• Strong back-end development experience using TypeScript
• Experience building and maintaining integrations with external APIs and third-party systems
• Ability to take ownership of projects from concept through production
• Strong problem-solving and communication skills

Desirable

• Experience with NestJS, GraphQL or Temporal.io
• Exposure to financial technology, SaaS, marketplace or e-commerce platforms
• Startup or scale-up experience
• Experience working on products with complex external partner ecosystems
