We offer a strong engineering culture and are looking for engineers to design and optimize high-performance trading systems that power our periodic auction matching infrastructure.
We build production systems in Rust and are seeking engineers with meaningful Rust, C++, Java, or Python experience, particularly from backend or systems-oriented environments.
Systems Engineer Systems programming role focused on low-latency, high-throughput distributed computing. Work across order and data workflows, auction execution, reliability, and performance optimization to ensure the platform is efficient, fault-tolerant, and capable of complex trade matching at scale.
We’re especially interested in engineers who: Have built backend or systems-level software Care deeply about performance, concurrency, and correctness Are motivated by real-time, performance-sensitive systems Have experience with compilers, static analysis, or language tooling (a strong plus)
Software Engineer, Data Platform Build and evolve the infrastructure behind our analytics platform. The role sits between data engineering and backend development and focuses on high-volume, time-sensitive data pipelines and workflow systems that process terabytes of trading data and billions of rows daily.
We’re especially interested in engineers who:
Have built internal data platforms or large-scale pipelines (Python/SQL; Rust a plus) Have experience with workflow orchestration (Temporal, Airflow, Dagster, etc.) Have worked with large datasets, columnar formats (Parquet/Arrow), and production data systems

We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
Hey, I'm one of Stellar's founders. We're building AI for large contact centers, our primary product is voice.
Everyone thinks contact centers are boring. They're wrong. It's the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here helps real people: shorter wait times, 24/7 support, lower cost. We’ve helped companies go from 60 to 98% pickup rate in weeks.
We're bootstrapped, 10 FTE, cash-flow positive, and growing fast with household names in the Netherlands and Belgium. Doubling our volume every month for the last 4 months.
We’re all builders. Everybody in our company still writes code. We have 2 roles open:
1. We need product minded engineers who can jump between our Go and TS backends and React frontend.
2. We need implementation leads that love working with clients. FDEs welcome as well.
This role is perfect if you:
* Want massive ownership at a small team
* Actually enjoy solving hard problems (real-time audio at enterprise scale)
* Think making AI sound human in niche dialects is a fun challenge
