Senior Backend Engineer – Distributed Systems

Company Description

Beacon is rebuilding the data and context layer for modern security operations. 

Today’s security teams are drowning in noisy, inconsistent telemetry collected through brittle pipelines and legacy tooling that were never designed for the speed, scale, or complexity of today’s environments. We’re a team of engineers, researchers, and builders creating a security-first data platform that shapes, enriches, and routes the right data to the right systems – from SIEMs to data lakes to AI-powered investigation tools. 

Backed by deep incident response and offensive security expertise, we’re helping organizations regain control of their telemetry, reduce operational drag, and unlock the visibility they need to defend at modern scale. We’re still early, growing fast, and looking for people who want to work on hard technical problems that materially change how defenders operate.

Role Description

We’re looking for a senior backend engineer with deep experience in distributed systems to help build and scale Beacon’s high-throughput data processing platform.

What You'll Do

• Design and implement core components of our distributed data pipeline.
• Build systems that process high-volume, heterogeneous security telemetry.
• Own architecture decisions and collaborate across engineering, product, and research.
• Improve resiliency, scalability, and operational efficiency.
• Develop abstractions that make onboarding new log types easier.
• Raise the engineering bar through code reviews and design discussions.

What We're Looking For

• 10+ years backend experience with distributed systems in production.
• Strong fundamentals in concurrency, fault tolerance, parallelism, and event processing.
• Proficiency in Go, Rust, or similar languages.
• Experience scaling systems in cloud environments.
• Product-oriented engineering mindset.

Nice-to-Haves

• Experience with security telemetry or observability pipelines.
• Systems programming or networking background.
• Experience with schema modeling or data normalization.

What Success Looks Like

• Reliable, high-throughput pipeline components that scale with customer needs.
• Clear architectural patterns that simplify future development.
• Meaningful performance improvements within the first few months.

Why Beacon

At Beacon, you’ll work on problems that matter: building the data foundations that modern security operations – and the next generation of AI-driven defense – will rely on. 

We’re a low-ego, high-ownership team that values clear thinking, strong engineering fundamentals, and the ability to turn complex ideas into real systems used by real security teams. You’ll collaborate directly with experienced IR and offensive researchers, shape products with immediate customer impact, and operate in an environment where good ideas move quickly from design to production. 

If you want to work on deep technical challenges, contribute to an architecture-first approach to security data, and help define a new category from the ground up, you’ll feel at home here.
