Mid-Level and Senior Software Engineers - Rust

Avaloq•Fort Lauderdale, FL

3d•$112,000 - $149,000•Hybrid

About The Position

Avaloq’s R&D Lab is building a SaaS, API-first, composable banking platform. The Software Engineer 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 positions at Avaloq’s new Fort Lauderdale development center and offer significant scope for ownership as the team grows. The position involves working directly with clients, seeing how solutions are used and bringing those insights back into the product. It includes onboarding with the Zurich team, collaborative mornings and productive afternoons, as well as regular travel to Switzerland and occasional travel to client sites. The technology stack includes Rust with Tokio and the AWS SDK for Rust. The platform is serverless-first on AWS, using Lambda, DynamoDB, SQS and S3, with GitHub Actions for CI/CD. Clients integrate through APIs and the Model Context Protocol (MCP); the company does not run containers. Relevant domain 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. Avaloq offers hybrid and flexible working for most employees and is committed to an inclusive, equal-opportunity workplace.

Experience in wealth or asset management technology, including investment performance, portfolio construction or 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.

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 analyse product questions, solve problems and bring insights back into product development.
