Engineering Open

As a Full Stack Software Engineer, you'll build reliable data link systems, optimise performance-critical code, and deliver expert TypeScript React frontends while collaborating across engineering teams to create seamless user experiences.

About the role

Join ZeroPhase as a Full Stack Software Engineer to design and deliver robust full-stack systems powering advanced data links. You'll optimise performance-critical code on ARM/x86, implement fault-tolerant networks, and create exceptional frontends with React. Working closely with cross-functional teams, you'll drive architecture, design, and code reviews, ensuring scalable solutions and outstanding user experiences through technical excellence and innovation.

What you'll do

• Develop highly reliable and available software systems for data links, including user front-ends with stand-alone GUI or web interface.

• Optimise signal processing code such as FFT or channel coding for ARM or x86 using NEON or AVX instructions.

• Design and implement highly available, fault-tolerant networks that operate for long periods with minimal maintenance at scale.

• Deliver expert-level TypeScript React code for modern browsers.

• Work closely with internal partners to drive successful outcomes for the business.

• Collaborate with other engineering teams across ZeroPhase to advance our engineering process in architecture, design, and code reviews.

• Deep dive into your users' problems to find and create efficient solutions.

• Bring your voice to the table in team collaborations on architecture, design, and code reviews.

What we're looking for

• Bachelor's degree in computer science, engineering, or a STEM discipline, plus 5+ years of experience building full-stack software; or 7+ years of professional experience building full-stack software in lieu of a degree (internship experience counts).

Bonus: not required

• Programming experience in Python, C++, Rust, or a similar object-oriented language.

• C++/Rust SIMD optimisation techniques.

• GUI design with Qt.

• Production experience with Docker and Kubernetes.

• Front-end experience in Angular, React, or a similar JavaScript framework.

• Database experience with MongoDB, SQL, or similar database technologies.

• Experience with version control, continuous integration, and continuous delivery concepts.

• Expertise in profiling and improving application performance, and experience with UNIX-like operating systems and CI/CD tooling.

• A drive to deliver exceptional user experiences for customers and a willingness to own all outcomes.

How the hiring process works

1. Intro call. 30 minutes with our recruiting team. We'll learn about your background, and you'll learn about the mission.
2. Deep dive. A working session with one of our software engineers on a real data-link or systems problem.
3. Case study, in Dortmund or Munich. A visit to the office to work through an architecture or code case study with the team, in person if you can make it or over Teams if you can't.
4. The offer. By now you've likely already met our CEO. This round is where we make it official: fast, transparent, and built around the mission.
