The Position
We are excited to welcome an experienced Software Engineer (Rust) to our expanding Technology Office team in Budapest.
In this mid-level position, you will contribute to the development and enhancement of high-performance Rust software that supports our products across on-premise, cloud, and hybrid deployments. You'll work with the modern Rust ecosystem and supporting tools to build reliable, safe, and efficient code as part of impactful projects. A key focus of the role is helping the Data Science team build a unified SDK that makes their AI-based features easy to integrate into Aether.
Joining a collaborative global team (with members in Vietnam, Spain, Romania, UK, US, Georgia, and Hungary), you'll work closely with senior engineers — both locally and remotely — in a supportive, international environment that values growth and innovation.
What You Will be Doing
Work with the Engineering Manager and Hungary-based team to plan, design, implement, and maintain Rust components and applications
Work closely with the Hungarian Data Science team, helping them build a unified SDK that wraps their AI-based models so these features can be integrated easily into Aether
Review requirements, contribute to feature design, and implement clean, idiomatic, maintainable Rust code
Write and maintain unit and integration tests; participate in code reviews to ensure quality and best practices
Create and update technical documentation for your work, including rustdoc for public APIs
Help identify opportunities for code improvements and participate in team discussions on enhancements
Collaborate with global engineers to deliver secure, reliable, and performant software
Support junior engineers through code reviews and pair programming, and keep growing into advanced systems topics
What We Need from You
Good foundation in Software Engineering principles
Good knowledge of Rust: ownership, borrowing and lifetimes, traits and generics, and idiomatic error handling with Result
Familiarity with Cargo and the Rust toolchain (rustup, clippy, rustfmt)
Good understanding of:
Concurrency in Rust: threads, Send/Sync, atomics, and synchronization primitives (Mutex, RwLock, channels)
Thread pools and producer-consumer patterns
