Job Description

You will design and operate high-performance Golang systems responsible for ingesting and processing massive volumes of internet data. Working across distributed systems, streaming pipelines, and customer-facing APIs, you will solve complex engineering challenges at the intersection of cybersecurity and large-scale data engineering in a high-trust, low-bureaucracy environment.

Why this role is remarkable

• Work at extreme scale, building systems that process 23.5 billion events daily—a volume of data most engineering teams will never encounter.
• Experience true ownership with zero layers of bureaucracy, moving projects from technical design to global production with direct influence on architecture.
• Join a category-defining company early, taking the lead on technical foundations that protect some of the world's most advanced organizations from cyber threats.

What You Will Do

• Design and scale real-time streaming systems and large-scale batch pipelines using Golang, Kafka, and ClickHouse to handle massive internet data.
• Build reliable, low-latency APIs and backend services that model and serve extremely large intelligence datasets to enterprise customers.
• Investigate complex failures across distributed infrastructure, improving observability and ensuring system resilience under heavy load and adversarial conditions.

The ideal candidate

• Has substantial production experience building and operating high-performance backend services in Go, specifically focused on distributed systems and data engineering.
• Demonstrates deep technical expertise with event-driven architectures, including hands-on experience with Kafka, ClickHouse, Elasticsearch, or Redis at scale.
• Possesses a pragmatic engineering mindset, capable of managing the full lifecycle of complex systems and making sound trade-offs regarding throughput, latency, and cost.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
