C# / .NET Developer – Front Office, Electronic & Low Latency Trading Systems

Join MARGO in the UK (London) – Perm & Contracting Opportunities

MARGO is a tech-native consultancy delivering high value-added IT expertise to the financial services industry.

We specialise in complex software engineering environments where performance, robustness and scalability are critical: real-time systems, low-latency architectures, distributed computing and high-throughput data processing.

Joining MARGO means working in demanding Front Office and Trading IT environments, while benefiting from a human-sized structure, close follow-up and tailor-made training paths.

Business Context

You will join the Front Office / Trading IT environment of one of our tier-1 investment banking or trading partners.

The teams design and maintain mission-critical C# / .NET systems supporting electronic trading, real-time risk and analytics platforms across multiple asset classes (Equities, Fixed Income, Commodities, FX, Derivatives).

These systems operate close to trading desks and electronic trading platforms, with strong constraints on performance, reliability and production stability.

The environment is characterised by:

Real-time and event-driven architectures
Low-latency and high-throughput processing requirements
Strong production and stability constraints
Close interaction with trading, quantitative and risk teams
High engineering standards and short delivery cycles

Role Overview

We are looking for an experienced C# / .NET Developer to work on real-time, electronic trading and risk systems.

The role is primarily technical and engineering-driven, focused on performance, scalability and robustness rather than business analysis.

Candidates are expected to have prior exposure to Front Office, Trading or Risk environments, regardless of the underlying asset class.

Key Responsibilities

Design & Development

Design, develop and maintain high-performance C# / .NET applications
Work on real-time data processing including market data, pricing, orders, analytics and risk calculations
Implement concurrency and parallel programming patterns adapted to performance-sensitive systems
Participate in system design, architecture discussions and technical specifications
Continuously optimise performance including latency, throughput and memory usage

Engineering & Delivery

Contribute to the full software lifecycle: design, development, testing and release
Produce clean, maintainable and well-tested code
Participate in sprint planning, estimations and technical reviews
Collaborate closely with developers, quant and infrastructure teams

Production & Support

Provide 3rd line support on production systems when required
Participate in production releases including occasional out-of-hours interventions
Contribute to system stability, monitoring and incident prevention

Technical Environment

Core Technologies

C# / .NET (expert level)

- Concurrency and parallel programming

- Asynchronous and multithreaded models

- Memory management and performance profiling

Distributed and event-driven architectures
Windows and/or Linux production environments
Performance monitoring and profiling tools

Valued Technical Exposure

Electronic trading or low-latency trading systems
High-throughput or real-time architectures
Messaging middleware (Kafka, Solace or equivalent)
FIX or other market connectivity protocols
RESTful or service-oriented architectures
High Performance Computing (HPC) or grid computing concepts

Required Experience & Skills

Essential

Strong experience as a C# / .NET Developer in performance-sensitive environments
Proven background in real-time or high-throughput systems
Solid understanding of concurrency, parallelism and memory optimisation
Experience working in Front Office, Trading or Risk IT environments
Strong production mindset and system ownership
Clear communication and structured problem-solving skills

Valued (but not restrictive)

Exposure to electronic trading platforms or low-latency environments
Experience across one or more asset classes (Equities, Fixed Income, Commodities, FX, Derivatives)
Familiarity with distributed, grid or event-driven systems
Interaction with C++ low-latency or HFT-adjacent components

Why Join MARGO

Access to multi-asset Front Office, Trading and Electronic Trading environments
Highly technical and challenging engineering assignments
Clear positioning between HFT and non-HFT trading systems
Strong emphasis on skill development and long-term career progression
Human-sized consultancy with close support and high-quality missions

Please note - We do not offer visa sponsorship for this position.
