Senior Software Engineer; Systems Engineering

At Local Stack we are building a high‑fidelity emulator and local cloud development platform to revolutionize cloud development processes. After closing our last $25 million round in Q4 2024, we are rapidly expanding a globally distributed team across Zurich, Vienna, the US, France, the UK, Canada, Spain and many other countries.

Our mission is to empower developers to rapidly build and test cloud applications, delivering an engaging dev experience while saving valuable time and resources.

• 5+ years of experience in systems engineering, backend development, or a similar low‑level technical role.
• Proven experience developing and maintaining container‑based runtime systems (e.g., Docker), with a strong focus on performance, reliability and cross‑environment portability.
• Solid understanding of container orchestration platforms such as Kubernetes, and experience building tooling or infrastructure to support complex deployments.
• Strong software engineering skills with proficiency in Python (or similar languages), and experience designing well‑structured APIs and system architectures.
• Familiarity with benchmarking, profiling, and optimizing distributed systems at the emulator or runtime level.
• Hands‑on experience contributing to or maintaining Open Source projects, with a collaborative and community‑first mindset.
• Comfortable taking ownership of core infrastructure components and driving projects from idea to delivery.
• Strong communication and collaboration skills, with the ability to work closely with product teams and customers to resolve technical challenges.
• Experience mentoring engineers, giving feedback, and helping build a high‑performing engineering culture.
• A proactive attitude and eagerness to work in a fast‑paced startup environment, continuously improving developer experience and cloud emulation capabilities.

• 5+ years of professional experience in software development with a strong foundation in designing, building and maintaining complex systems.
• Proficiency in systems‑level languages such as Rust, C, or C++, and/or high‑level languages like Python.
• Deep understanding of Linux system APIs and internals, including networking, name spaces and tracing mechanisms.
• Hands‑on experience with advanced debugging and observability tools such as perf, eBPF, strace, and similar.
• Proven ability to debug and trace application behavior in complex containerized setups (e.g., Docker, Kubernetes), addressing issues like crashes, networking, resource constraints and permission errors.
• Familiarity with both application‑level and platform‑level cloud development, and Infrastructure‑as‑Code tools such as AWS CDK, Terraform or Pulumi.
• Experience in coaching and mentoring engineers, fostering a culture of learning and technical excellence.
• Exposure to working across Engineering, Developer Relations and Go‑to‑Market teams to align on product goals and delivery (nice to have).
• Experience interfacing directly with customers to gather requirements, troubleshoot issues and deliver technical solutions.
• Background in team or technical leadership, including ownership of critical projects and architectural decision‑making (nice to have).

• Fully remote
