Job description

I'm working with a highly successful buy-side investment manager that's investing heavily in software engineering, data platforms and AI as part of a firm-wide technology transformation.

They're looking for a Senior Software Engineer to join a small, high-performing team where engineers have genuine ownership, work directly with investment, finance and operations teams, and deliver technology that has a visible impact across the business.

This isn't a role where you'll spend years maintaining a single application. You'll lead projects from design through to deployment, building modern business systems, cloud data platforms, APIs, automation and AI-enabled solutions that support the firm's investment platform.

The business has embraced AI-assisted engineering, with developers actively using Claude Code, OpenAI Codex and modern AI tooling as part of their day-to-day development process while exploring agentic workflows across the organisation.

What You'll Be Working On

• Designing and building full-stack applications and internal business platforms using C#/.NET
• Developing APIs, integrations and cloud-native solutions across Azure
• Building and maintaining Azure SQL and ETL/ELT data pipelines
• Modernising reporting, automation and operational workflows
• Working directly with investment, finance and operations stakeholders to solve complex business problems
• Building AI-enabled solutions and leveraging modern AI tools to improve software delivery

What They're Looking For

• Experience building business applications, APIs and backend services
• Experience with Azure technologies such as Azure Data Factory, Logic Apps, Function Apps or similar cloud services
• Experience designing or supporting ETL/ELT pipelines and data platforms
• Familiarity with CI/CD pipelines and modern software engineering practices
• Comfortable working directly with business stakeholders and owning technical delivery
• Experience using AI tools to accelerate software development

Experience within asset management, private markets, private equity, banking, hedge funds or other regulated financial services environments would be highly advantageous.

Why Join?

• High ownership and autonomy from day one
• Direct exposure to investment professionals and senior business stakeholders
• Broad engineering role spanning software, cloud, data engineering and AI
• Opportunity to influence technology strategy within a growing investment platform
• Hybrid working and highly competitive compensation

For engineers who enjoy solving complex business problems, owning solutions end-to-end and working at the intersection of software engineering, data and AI, this is a genuinely outstanding opportunity.
