Job summary

Referment is hiring a Senior Software Engineer for the post-trade and reporting team. You will build backend services used by operations and fund accounting, combining backend engineering with deep business process knowledge.

There is direct interaction with users and stakeholders, no intermediary layer, and you will influence the platform's technical direction as distributed, event-driven systems evolve. You will own design reviews and ensure maintainable, observable production systems.

Qualifications

• Five+ years of professional software development, including distributed or microservices-based systems.
• Strong backend engineering fundamentals; C#/.NET preferred; other modern tech also valuable.
• A STEM degree and disciplined approach to testing, documentation, and version control.

Responsibilities

• Define problems with operations and senior stakeholders and design practical software solutions.
• Lead changes through architecture, data modelling, implementation, testing and release.
• Build backend services with reliable failure handling, monitoring and alerting in production.
• Improve shared components and delivery tooling, including CI/CD and IaC.

Job description

Referment is working with a quantitative investment manager to hire a Senior Software Engineer for its post-trade and reporting team. You will build the systems used by operations and fund accounting, combining backend engineering with a close understanding of the business processes the software supports.

There is no business analyst layer between you and the people using these systems. You will discuss their requirements directly, work through the design and carry the solution into production. That makes this a role for someone who wants to understand why a system is needed as well as how to build it.

The remit spans new projects and improvements to existing services. Alongside delivery, you will help shape the platform's technical direction and make its distributed, event-driven systems easier to monitor, operate and maintain.

The Role

• Work with operations, fund accounting and senior stakeholders to define problems and agree practical software solutions.
• Take changes through architecture, data modelling, implementation, automated testing and release.
• Build backend services that handle failure predictably, with monitoring and alerting that make production behaviour visible.
• Improve shared components and delivery tooling, including CI/CD and infrastructure-as-code.
• Contribute to design reviews and technical decisions, balancing new approaches with the needs of an operating investment business.

What We're Looking For

• At least five years of professional software development, including cloud-distributed, event-driven or microservices-based systems.
• Strong backend engineering and computer science fundamentals. C#/.NET is preferred, with relevant experience in comparable technologies also valuable.
• A STEM degree and a disciplined approach to testing, documentation, version control and maintainable design.
• Confidence gathering requirements and explaining technical choices directly to business users.
• Curiosity about development tools, including AI-assisted engineering, alongside sound judgement about where to use them.

Useful Background

The environment includes AWS, Docker and Kubernetes, with PostgreSQL and SQL Server for data and Angular/TypeScript on the frontend. Database tuning and financial-services experience are useful, rather than prerequisites for every candidate.

This could suit a backend engineer who enjoys business-facing ownership and wants to stay involved after the code reaches production, rather than hand off a finished component and move on.
