About Us

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.

Position Overview

As a Principal 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.

Expected Impact

  • Architect, build, and maintain core functionality for our customer-facing product across the stack

  • 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

Qualifications

  • 8+ years of full stack software engineering experience

  • Proficiency in Python, Go, Java, or Rust

  • Strong experience with Typescript

  • Experience with either AWS or GCP

  • Opinionated about frontend design systems and what makes a good UI

  • Experience working with microservices

  • Strong fundamentals in API design, data modeling, and distributed systems

  • Demonstrated ability to translate ambiguous customer needs into technical solutions

  • Ability to adapt, iterate, and ship quickly

  • Hunger for growth and the desire to work in a low-ego environment

Nice to Haves

  • Experience with Angular

  • Cybersecurity experience

  • Startup experience

  • Experience building agentic systems

  • Experience with Devops or Infrastructure

About Nebulock

Nebulock is the first agentic threat hunting platform; autonomously surfacing behaviors, not just IOCs, from your existing data. Nebulock acts like a new teammate: a 24/7 AI threat hunter that investigates hypotheses, reasons through your telemetry, and learns from your environment. Whether you’re a two-person SOC or a global enterprise, we scale your threat hunting - and give your team superpowers. Today, threat hunting is broken. Security teams spend weeks chasing alerts, writing detections by hand, and manually validating findings - often just to confirm what their existing tools already flagged. Meanwhile, attackers exploit credentials, move laterally, and operate in silence. Nebulock flips the model. We continuously and autonomously hunt across endpoint, identity, and cloud telemetry - identifying the subtle behavioral signals that point to credential misuse, lateral movement, insider threats, and post-access activity. Then we turn those hunts into hardened, behavior-based detections - automatically. No new agents No alert regurgitation No workflow disruption Just high-fidelity, explainable findings - delivered directly to your SIEM, API, or Slack.
