Mid-Level and Senior Software Engineers - Rust

About the Position

Avaloq’s R&D Lab is building a SaaS, API-first, composable banking platform. You will help develop its Rust backend, creating financial technology where precision, quality, and scalability matter, while working closely with engineers in Fort Lauderdale and Zurich.

These roles are among the first engineering roles at our new Fort Lauderdale development center, offering significant scope for ownership as the team grows. You will work directly with clients, see how your solutions are used, and bring those insights back into the product. The role includes onboarding with the Zurich team, collaborative mornings, and productive afternoons, with regular travel to Switzerland and occasional travel to client sites.

Our stack

• Rust with Tokio and the AWS SDK for Rust
• Serverless-first on AWS, using Lambda, DynamoDB, SQS, and S3
• GitHub Actions for CI/CD
• Clients integrate through our APIs and the Model Context Protocol (MCP)
• We do not run containers

Useful domain experience

Depending on the role, relevant experience may include wealth and asset management, discretionary portfolio management, investment performance and attribution, portfolio valuation and rebalancing, benchmarks and fees, or US investment taxation, including tax lots, cost basis, holding periods, wash sales, corporate actions, withholding, and tax reporting.

Responsibilities

• Design, develop, and test Rust backend services for complex financial products, with a focus on accuracy, scalability, and reliability.
• Translate complex financial rules and mathematical concepts into precise, efficient, and testable software, accounting for numerical precision and edge cases.
• Build scalable solutions using historized, non-relational data models and asynchronous, event-driven architectures.
• Contribute to technical specifications, design discussions, and code reviews, using AI coding agents while maintaining rigorous review standards and accountability.
• Own features through the development lifecycle, from implementation and automated testing to deployment and monitoring, working alongside Platform and SRE engineers.
• Work directly with clients and domain specialists to analyze product questions, solve problems, and bring insights back into product development.

Requirements

• Strong programming foundations in a statically typed language such as Rust, C++, Java, Scala, Kotlin, C#, Go, or TypeScript.
• Master’s degree or PhD in computer science, mathematics, physics, or a related quantitative field.
• Strong modelling skills, including experience or understanding of historized data, effective dating, immutability, and audit trails.
• Strong analytical ability and intellectual curiosity, with the ability to quickly learn new technologies and complex financial domains.
• Clear and confident communication skills, with the ability to explain technical concepts effectively to both technical and business audiences.
• Ability to work independently within a distributed team and travel to Switzerland and client sites when required.

Nice to Have

• Production Rust experience, or experience with another systems/strongly typed language such as C++, Haskell, OCaml, or Scala.
• Experience in wealth or asset management technology, including investment performance, portfolio construction/rebalancing, or tax, accounting, and other rule-heavy financial software.
• Experience with AWS serverless and event-driven architecture, particularly Lambda, DynamoDB, SQS, S3, and API Gateway, or related distributed-systems technologies.
• Experience with AI-assisted engineering, client-facing product development, research, or open-source software.

We Offer

• Annual bonus or sales reward
• Flexible working
• Kudos instant recognition scheme
• Access to Udemy for professional and personal learning
