Job description

Role Summary

The Forward Deployed Engineering (FDE) team at FINBOURNE works directly with our pre and post sales clients, who range from small start-up hedge funds to multi-national financial service providers, to understand their business problems and turn them into working solutions on LUSID and Luminesce. The role combines hands‑on software engineering with deep financial domain expertise: FDEs design and build client‑specific capability and integrations, configure the platform, and act as the client’s trusted technical and domain partner across the full delivery lifecycle.

We are looking for a Senior FDE to own a client workstream end to end. You will handle the majority of product, domain, and delivery questions yourself, set the technical and quality bar for the work, run the client relationship at an operational and steering level, and be the person the client asks for by name. This is a senior, client-facing role for someone equally comfortable debugging across a full technology stack and holding a difficult conversation with senior client stakeholders. You will gain broad exposure across the business, work across a varied technology stack, and carry real ownership from the start.

Key Responsibilities

• Own the technical design and delivery of a client workstream end to end: scoping and sequencing the work, deciding what gets built, building the harder pieces yourself, and reviewing and improving the rest.
• Translate a client’s operating model into LUSID structures across the asset classes and operational workflows they run, without needing separate domain support.
• Debug across the full stack, spanning LUSID, Luminesce, the SDKs, workflows, deployment, and system resources, and pinpoint whether an issue sits in the product, the configuration, or the client’s data.
• Build and configure client solutions: data pipelines and integrations, Luminesce queries, workflows, scheduler jobs, and config-driven deployments using fbnconfig.
• Own the workstream plan, RAID, milestones, and status, and run steering committees and difficult conversations directly with the client.
• Act as the client’s voice inside FINBOURNE for product, prioritisation, and escalations, feeding client requirements into our Product and Engineering teams to support the specification and testing of new functionality.
• Set and hold the engineering and quality bar across the engagement, including the work of others, and mentor FDEs and graduates through code review, design review, and day-to-day guidance.
• Spot expansion and scope opportunities during delivery, contribute to scope and pricing conversations, and estimate effort credibly.
• Deliver technical content, training, and client-facing documentation, and help build the wider community of LUSID users.

Skills and Experience

Essential

• Basic C# knowledge, with a grasp of object-oriented fundamentals and the ability to read and follow an existing codebase.
• Familiarity with command-line AI coding tools (e.g. Claude Code, or similar) and a genuine interest in using them to work more effectively.
• Strong analytical and problem-solving skills, with the ability to investigate discrepancies methodically and trace issues back to their root cause.
• Clear written and verbal communication, particularly the ability to document findings and explain technical detail to non-engineering colleagues such as the support team.
• A collaborative, proactive mindset, comfortable working in an informal, agile environment and switching between support and development work.
• An eagerness to learn, with a keen interest in financial instruments, valuations, and building well‑tested software.

Desirable

• Working knowledge of C#, with the ability to debug and extend a commercial codebase independently.
• Exposure to financial services concepts (valuations, P&L, IBOR/portfolio management).
• Experience with automated testing (e.g. NUnit), Postgres, Docker/Kubernetes, or cloud platforms (AWS/Azure).
• Familiarity with CI/CD workflows.

Just some of our benefits

• Competitive salary plus performance based bonus.
• Health & Wellbeing: A competitive health insurance policy that disregards previous medical history. This also includes dental, optical, mental health support and comprehensive cancer cover.
• Cycle to work scheme and Gym discounts: Buy a bike and cycling accessories out of your pre-tax salary and spread the cost over 12 months, as well huge discounts off Hussle, KOBOX and Nuffield Health gyms.
• Hybrid: We have a mature attitude towards hybrid working. Whether you’re a night owl, morning person, parent, carer or simply need flexibility to work a different pattern to the norm, we’re committed to helping you be productive and work in a way that is best for you.
• Professional learning and development: External training and accreditations are supported, as well internal training and development programs.
• Maternity, paternity and adoption leave: Paid maternity, paternity and adoption leave, which includes 13 weeks full pay for maternity and adoption leave and 6 weeks full pay for paternity leave
• Holiday: 25 days holiday plus bank holidays
