Rust Jobs for Rustaceans

About the Role
Are you a seasoned software engineer with a passion for technology and a knack for solving complex problems? Join our dynamic team in Warsaw, Poland as a Senior Software Engineer, where you'll play a pivotal role in designing, building, testing, deploying, and maintaining our critical trade management system. Our primary development is in Rust, and you'll also work with and support C#/.NET components where appropriate.
 
We are leveraging Rust to maximize throughput and reliability, minimize memory usage, and ultimately reduce compute and memory costs across our AWS environment (including serverless workloads). You'll work on distributed systems and high-volume processing, collaborating with talented engineers across the globe.
 
Key Responsibilities:

• Innovate and Enhance: Design and build Rust-based, multithreaded, high-volume trade flow processing systems.
• Interoperate: Integrate with existing C#/.NET services and contribute to those codebases as needed.
• Performance & Cost: Profile and optimize latency, memory usage, and resource footprints to reduce AWS costs.
• Decision Making: Make independent decisions while effectively mitigating risks.
• Ownership Mentality: Take full ownership of all aspects of our trade management systems.
• Fast-Paced Environment: Thrive in a fast-paced setting, balancing second-line support with strategic development responsibilities.
• Global Collaboration: Work closely with engineers in the UK, New York, Singapore, and Hong Kong to deliver robust solutions.

 
Requirements:

• Experience: 8+ years of hands-on experience in a formal enterprise-level development environment, with significant production experience in Rust. Comfort working with C#/.NET is required.
• Strong expertise in Rust (async/await, concurrency, memory/ownership model, multi-threaded programming) and solid software design skills.
• Proficiency with C# and .NET Core to read, support, and contribute to .NET services where needed.
• Proven experience in building connected, service-oriented applications (e.g., REST/gRPC, microservices).
• Familiarity with enterprise messaging systems (e.g., Kafka, RabbitMQ, SQS/SNS).
• Experience with AWS, including serverless technologies (e.g., Lambda) and an understanding of how performance and memory optimizations translate to cost savings.
• Communication: Excellent verbal and written communication skills, with the ability to explain complex ideas clearly to various audiences.
• DevOps Knowledge: Experience with JIRA, Git, Jenkins, and Octopus Deploy.

 
Bonus Points for:

• Agile Development: Familiarity with Agile software development concepts.
• Test-Driven Development: Experience with behavior- and test-driven development; familiarity with Rust testing frameworks (e.g., proptest/quickcheck) is a plus.
• Full Stack Development: Knowledge of web and mobile frameworks such as React JS and Angular.
• Financial Markets: Understanding of the FIX protocol, MS SQL, and familiarity with US and International Equity, Fixed Income, and Commodity markets.
• Post-Trade Lifecycle: Insight into the post-trade lifecycle processes.

 
Why Join Us:

• Impactful Work: Contribute to critical systems that drive our trading operations.
• Professional Growth: Gain exposure to the business side of trading operations and post-trade processing.
• Collaborative Environment: Work closely with a talented team in a supportive and innovative environment.
• Global Network: Collaborate with engineers from the UK, New York, Singapore, and Hong Kong.
