Job description

Overview

Hands-on .NET Architect to lead the design and build of a low-latency, production-grade FIX engine and connectivity layer for front-office trading workflows. You will own architecture decisions, performance engineering, and delivery of FIX connectivity integrating venues and platforms such as Bloomberg TOMS, Tradeweb, and downstream middle/back-office systems.

Desired Skills and Experience

• 7+ years in software engineering with strong experience in .NET / C# and architecture ownership.
• Proven experience building FIX protocol integrations (FIX 4.2/4.4/5.0), including sequencing, session state, replay/resend, and drop-copy concepts.
• Strong understanding of capital markets trading workflows (RFQ, order/execution lifecycle, allocations, post-trade flows).
• Experience with low-latency engineering: profiling, GC tuning, latency benchmarking, and high-performance orchestration.
• Solid experience with distributed systems, concurrency, and fault-tolerant design.
• Strong knowledge of security in financial systems (TLS, certs, secure configuration, secrets management).

Domain & Nice-to-Have Experience

• Direct integration experience with Bloomberg TOMS and/or Tradeweb connectivity patterns.
• Familiarity with FIX engines/libraries (e.g., QuickFIX/QuickFIXn or equivalent) and when to extend vs build.
• Experience with Kafka, MQ, Redpanda.
• Linux + containerization (Docker/Kubernetes) and production operations in on-prem / hybrid environments.
• gRPC, WebSockets, or binary protocols for internal distribution.
• Cloud exposure (Azure/AWS), especially for observability and secure networking.

Key Responsibilities

• Architect and deliver a scalable FIX connectivity platform (client/server, initiator/acceptor) supporting multiple counterparties and venues.
• Define hot-path performance patterns (zero/low allocations, object pooling, efficient parsing/encoding, deterministic latency).
• Build session management, message routing, sequencing, resend/replay, and store-and-forward mechanisms aligned to FIX standards.
• Implement message normalization and canonical domain models (orders, RFQs, executions, allocations).
• Integrate with trading platforms/venues (e.g., Bloomberg TOMS, Tradeweb) and internal systems via FIX and/or messaging layers (Kafka, MQ).
• Establish secure connectivity (TLS, cert management, key rotation), auditability, and full observability (metrics, tracing, log correlation).
• Define HA/DR architecture (active-active / active-passive), failover strategy, and resilience testing.
• Own engineering standards: code reviews, performance benchmarks, capacity planning, release automation, and runbooks.
• Mentor engineers and collaborate with product, trading, and operations stakeholders.
• Effectively communicate with business and technology partners, peers and stakeholders.
• Ability to deliver results under demanding timelines to real-world business problems.
• Ability to work independently and multi-task effectively.
• Identify and communicate areas for improvement.
• Demonstrate high attention to detail, work in a dynamic environment while maintaining high quality standards, develop good internal working relationships, and maintain a flexible work ethic.
• Responsible for Quality Checks and adhering to the agreed Service Level Agreement (SLA) / Turn Around Time (TAT).
