Role Overview

As a Lead Engineer on our Warsaw Trade Processing team, you will be a senior technical owner responsible for the design, architecture, and delivery of the platforms that power the firm's post-trade lifecycle. This is a hands-on, player-coach role: you will spend the majority of your time architecting and building production software, while providing technical leadership and light people management to a small team of engineers (approximately four direct reports).

You'll partner closely with a global Operations Technology group to onboard new products onto the trade processing platform, drive the ongoing migration of the stack from C# to Rust, and set the technical direction for a high-volume, distributed system that underpins the firm's Equity, Macro, Multi-Asset Arbitrage, and Commodities strategies.

We're looking for an engineer who leads primarily through technical excellence and delivery—someone who is energized by building, not just directing.

Key Responsibilities

• Own the architecture of high-throughput, horizontally scalable, distributed trade processing systems, ensuring they are reliable, recoverable, and scalable as volumes and product coverage grow.

• Spend at least 50% of your time hands-on—designing, writing, reviewing, and delivering production code.

• Own the full post-trade lifecycle—trade capture, validation, enrichment, allocation, confirmation, settlement, reconciliation, and exception management—across multiple asset classes and strategies.

• Onboard new products onto the trade processing platform, working directly alongside a small team of engineers.

• Lead the C#-to-Rust migration, establishing patterns, standards, and best practices as the platform evolves.

• Use AI-assisted development tools to accelerate delivery, and help establish the engineering standards, governance, and best practices for their responsible and effective use across the team.

• Provide technical leadership and light people management—mentoring engineers and supporting their project and career development.

• Act as a technical liaison, translating business needs into technical strategy and ensuring alignment with global development initiatives.

• Define and drive technical roadmaps, balancing near-term delivery with long-term platform health and continuous improvement.

Required Qualifications

• 5+ years of enterprise software engineering experience, with demonstrated technical leadership and ownership of significant systems.

• Strong command of C#/.NET and service-oriented / distributed architecture, with deep understanding of concurrent and high-performance programming techniques. Experience with, or strong interest in, Rust (the platform is actively migrating to Rust).

• Demonstrated experience using AI tools to accelerate enterprise software delivery—e.g., AI coding assistants / agentic development tools, AI-assisted testing, code review, and documentation—along with the judgment to establish standards and governance for their use.

• Experience designing systems that are reliable, recoverable, and scalable under high volume.

• Excellent communication skills, capable of translating complex technical concepts for both technical and business audiences.

• Familiarity with modern DevOps practices and tooling (e.g., JIRA, Git, Jenkins, Octopus Deploy).

• Ability to provide light people management and mentorship to a small team of engineers.

Desirable Experience

• Hands-on experience with Rust in production systems.

• Strong foundation in agile methodologies and test-driven development.

• Experience with AWS and cloud-native / serverless architecture (e.g., Lambda, DynamoDB) and streaming technologies (e.g., Kafka).

• Full-stack development experience with modern UI frameworks (React, Angular).

• Knowledge of the FIX protocol, advanced database systems, and event-driven / streaming architectures.

• Understanding of the post-trade lifecycle across US and international Equity, Fixed Income, and Commodity markets.

Even if your experience doesn’t match every requirement, we’d still love to hear from you—if you’re excited about this role, we encourage you to apply!
