Senior C# Engineer – Global Payments & OTC Energy | 130,000| Front Office | London | 3-days in office
Location: London (Central) Working Pattern: Hybrid (3 Days Office / 2 Days Remote) Sector: Global Financial Services & Liquidity Provider (Nasdaq Listed)
The Mission: Architecting a High-Performance Payment Backbone
Our client is not looking for a "ticket-taker." Following their 2024 Nasdaq listing, they are scaling a globally distributed payments platform and an OTC Energy risk engine. This is a high-visibility "builder" role where you will be tasked with solving the complexity of real-time global liquidity.
You will join an elite, business-aligned squad that functions like a fintech pod within a global powerhouse. Your mission is to deliver low-latency, event-driven architectures that can handle the massive throughput of the modern energy markets.
We are looking for engineers who treat C# as a high-performance instrument.
- The Core: Mastery of Modern .NET (8/9). You should be comfortable with memory management, Zero-GC allocation patterns, and high-concurrency scenarios.
- Cloud-Native Architecture: Designing and deploying Immutable Infrastructure on AWS using Terrafo.
- Distributed Systems: Deep experience with Event-Driven Workflows (Kafka/RabbitMQ) and designing High-Throughput APIs that maintain 99.99% resiliency.
- Full-Stack Capability: Proficiency in React/TypeScript for building low-latency, real-time trader dashboards.
- Engineering Rigor: A "test-first" mindset (TDD/BDD) and a mastery of SOLID and Clean Architecture.
Your Impact
- Direct Business Proximity: You will sit within the OTC Energy stream, working with traders to translate market volatility into robust software solutions.
- Leadership & Mentorship: You will own the developer ecosystem, driving an automation-first DevOps culture and mentoring the next generation of engineers.
- Legacy Modernization: Leading the transition from legacy warehousing to Snowflake, enabling faster alpha generation and real-time reporting.
Why this role stands out (The 2026 Benefits)
- High-Alpha Bonus Culture: Move away from the capped "Retail Bank" bonus pools. This role is tied to the performance of a high-growth, Nasdaq-listed front-office business.
- Modern Hybrid Flexibility: A sensible 3/2 split in a tech-first office designed for collaboration, not just desk-sitting.
- Greenfield Scope: You are joining at the start of a multi-year platform reimagining—you will have "Sovereignty" over architectural decisions.
