The Role:

As a Senior Systems Software Engineer, you will be a key individual contributor to the design and implementation of the Error-Reporting/Backtrace platform. You will focus on building high-performance features that allow our customers to analyze multi-dimensional data and debug production issues at scale.

Leveraging your expertise in native, low-level systems (Rust, C/C++), you will work directly on our custom columnar database and core backend services. You are expected to be a master of your craft, writing efficient code while maintaining a DevOps mindset to ensure the platform remains scalable and reliable. You will work within a global team, taking ownership of complex components and translating technical requirements into robust software solutions.

Responsibilities:

  • Implement and maintain core subsystems including work scheduling, networking (HTTP), storage, and indexing. You will write performance-critical code in Rust and C/C++.
  • Implement and refine OpenTelemetry integrations (metrics, tracing, and profiling) and build out Grafana dashboards to monitor system health and performance.
  • Take ownership of technical tasks from design to deployment, ensuring they meet the high standards of our performance-sensitive environment.
  • Provide guidance to junior and mid-level engineers through code reviews, pair programming, and documentation.
  • Participate in the on-call rotation and contribute to the automation of the software development lifecycle (CI/CD) to improve team velocity.
  • Assist in the development and integration of AI-driven features and agents that enhance internal workflows and customer debugging experiences.

Required Skills:

  • 5+ years of professional development experience, with a heavy focus on C/C++ and Rust.
  • Strong understanding of systems programming, including memory management, concurrency, and I/O.
  • Experience building or maintaining distributed systems or high-performance databases.
  • Proficiency with cloud infrastructure, specifically GCP or AWS.
  • Hands-on experience with Docker, Kubernetes, and CI tools like Jenkins.
  • Expertise in debugging complex systems using both live and post-mortem tools.
  • A pragmatic approach to problem-solving—you value "done" over "perfect" but never sacrifice system stability.
  • Effective communication skills for collaborating with a distributed, global team.

This Saucer can be found globally.  We believe in the power of in-person collaboration to build strong relationships and drive innovation. To support this, our office models are tailored by region:

  • Poland, Berlin, and the US: We operate on a hybrid basis, offering flexibility alongside collaboration with in-office days as required.
  • India: We operate in-office 5 days a week to maximize team synergy and real-time collaboration and mentorship.

Regardless of location, Saucers living near an office are expected to be present and engaged with their local teams.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
