Post-Trade Software Engineer

2 weeks ago

London Area, United Kingdom Mondrian Alpha Full time €35,000 - €60,000 per year

We are working with a high-performing buy-side technology team that is hiring four Software Engineers to help build and evolve their Post-Trade Engineering function. This is an opportunity to work in a modern, low-bureaucracy environment where engineering is central to the firm's success and where technology directly enables trading, risk, operations and portfolio management.

You will join a small, highly capable team responsible for the full lifecycle of post-trade systems: trade capture, enrichment, lifecycle events, reconciliations, settlement workflows, data pipelines, and regulatory/operational reporting. The team operates with significant autonomy, close collaboration with business stakeholders, and ownership from design through to production.

The Role

You will:

  • Design, build and enhance post-trade services covering trade capture, validation, enrichment, lifecycle processing and settlement flows.
  • Develop reconciliation tools and exception-handling systems for multi-asset trading activity.
  • Build robust data pipelines and operational datasets for risk, P&L, compliance and audit requirements.
  • Integrate with brokers, custodians, clearing venues and internal trading/risk systems.
  • Work directly with operations, risk, finance, compliance and portfolio managers to understand workflows and translate them into clean, scalable engineering solutions.
  • Contribute to architecture, technical design, testing, automation, observability and ongoing platform modernisation.
  • Ensure resilience, reliability and data quality across high-impact operational systems.

What We're Looking For

  • Strong software engineering skills in Python or C# (Python/Scala useful for data-heavy components).
  • Solid understanding of data modelling, relational databases (SQL Server, Oracle, PostgreSQL) and building performant queries/schemas.
  • Experience with post-trade, middle-office, or trade-lifecycle engineering — e.g. reconciliations, settlements, allocations, confirmation workflows, corporate actions, or similar.
  • Experience with event-driven systems, messaging, or streaming platforms (Kafka, MQ, etc).
  • Strong understanding of financial markets and trade lifecycle across one or more asset classes.
  • Ability to engage with non-technical stakeholders and translate business logic into maintainable systems.
  • Pragmatic, detail-driven engineering mindset: building reliable, well-tested, production-grade systems.

Why This Opportunity?

  • Small, high-quality engineering team with direct ownership and minimal red tape.
  • Broad remit across all facets of post-trade processing and operational data flows.
  • High visibility with senior technologists and business stakeholders.
  • Opportunity to shape the future architecture of a critical function in a fast-growing, technology-first environment.
  • Genuine engineering culture – clean code, modern tooling, autonomy and accountability.

Location:
London

Work Model:
(4 days onsite)

Compensation:
Highly competitive, aligned to top-tier buy-side standards.

If you are a strong engineer with exposure to post-trade or middle-office systems and want to contribute to a modern, mission-critical platform, please reach out for a confidential discussion.
