Senior Backend Engineer (Rust)

TalentCo are thrilled to be working with a VC-backed AI infrastructure startup building the future of multimodal data systems. Having recently raised a substantial Seed round, they are now looking to hire an exceptional backend focused Senior Rust Engineer to join their high-calibre, distributed team in Europe.

You’ll play a key part in designing and scaling core systems for a new class of analytical databases purpose-built for high-throughput, multimodal time-series data. Working in Rust, you’ll architect performant, scalable systems that handle everything from ingestion and indexing to complex query execution.

If you\’re keen to be at the sharp-end of the AI boom, love building technical infrastructure from the ground up, care deeply about performance, and want to work with a highly talented remote team, this is a perfect fit.

This is a fully remote position open to candidates based anywhere in Europe or the UK.

As Senior Backend Engineer (Rust) you will:

• Design and build a cloud-native analytical database system optimised for sparse, wide, and multimodal logs.
• Work with technologies like Rust, Apache Arrow, and Datafusion to build scalable, low-latency systems.
• Collaborate on every part of the stack—from data ingestion and indexing to query planning and optimisation.
• Build observability, reliability, and scalability into a product being designed for some of the most demanding data applications in the world.
• Operate in a high-agency environment alongside experienced engineers and founders, helping shape both product and tech strategy.

We want to hear from you if:

• You have 3+ years experience writing asynchronous Rust in production environments.
• Perhaps you\’ve worked at another early-stage startup, within Big Tech or built data infrastructure tools – we\’re open on your background but a mix of the above would be awesome.
• You have a deep understanding of systems programming and performance engineering.
• You’ve built scalable, data-intensive infrastructure before and can navigate the entire stack.
• You have experience deploying and operating backend systems in the cloud (AWS, GCP, or Azure).
• You speak fluent or business-level English and are a great collaborator who thrives in tight-knit, remote-first teams.

What do they offer?

• Salary between £85,000 – £130,000 dependent of experience
• Generous equity package
• 30 days paid vacation
• Work from anywhere in Europe or the UK
• All the tools and equipment you need to do your best work
