Full Stack Engineers (Senior & Principal)

Location: Boston or US Remote

Nebulock builds hunt-first, behavior-first security operations. Enterprise security teams use us to find attackers already inside their environment by spotting behavior that's abnormal for that organization, rather than by matching signatures of attacks someone has already seen. Attackers rotate tooling constantly and it costs them almost nothing; changing how they behave is much harder.

Series A, $34M total raised led by FirstMark, with Bain Capital Ventures, Decibel, Zetta, Step Function, and In-Q-Tel. Founding team out of CrowdStrike, Palo Alto Networks, and Arctic Wolf.

The platform is a closed loop:

• A per-customer behavioral system of record that learns what normal looks like in a specific environment and gets more useful the longer it runs

• Detections built from that context, re-baselining as environments shift, maintained by a detection engineering team rather than shipped and forgotten

• Autonomous hunting agents that work from a hypothesis instead of an alert, and write the detection when they establish root cause

• Detection engineering agents that take the context of threat hunts run to build, test, validate and deploy behavioral detections for Nebulock customers.
  

As a Full Stack Software Engineer at Nebulock, you will own the end to end product experiences that power our hunt-first security operations platform. You will architect, build, and maintain the systems that our customers interact with on a daily basis. You’ll work on solving a wide range of problems for our customers, from ensuring that the threat intelligence we surface is relevant to each customer’s environment, to building a customer-facing query builder that enables customers to build composite detections. You’ll collaborate closely with our product organization, our internal threat hunters and detection engineers, and our data platform team to ensure that we are solving real customer problems. This role is ideal for engineers who want significant ownership over customer-facing systems and who enjoy touching all parts of the stack from the database layer up to the UI.

• Collaborate cross-functionally to ensure we are delivering an innovative and impactful product

• Propose architectural changes across the stack that allow us to move quickly while ensuring that our systems are scalable and maintainable

• Help set engineering standards across the organization (e.g. AI tooling, public facing API standards, testing standards)

• Co-own the technical roadmap and advocate for the technical investments that matter most

• Mentor other engineers on the team to ensure Nebulock engineering is constantly getting better

• 8+ years of full stack software engineering experience

• Proficiency in Python, Go, Java, or Rust
