Requirements

  • You have hands-on experience building AI-assisted features, LLM-powered workflows, or agentic systems (or strong practical exposure through prototypes and iterative delivery)
  • You can explain how you evaluate and operate these systems in production (quality metrics/evals, monitoring, rollout strategy, and failure modes)
  • You’re comfortable working in ambiguous problem spaces, breaking problems down to first principles, and delivering in small, validated iterations
  • Experience or knowledge with agentic architectures (tool use/function calling, workflow orchestration, retrieval/RAG, and human-in-the-loop patterns)
  • Experience or knowledge with AI/LLM evaluation approaches (golden sets, offline/online evals, experimentation, prompt/versioning discipline)
  • Amazon Web Services
  • HackerOne Values
  • HackerOne commits to maintaining a strong, inclusive culture built for our employees and our community of security researchers. We are driven by our five core values. We recognise that our mission is bigger than us, and therefore, we act with integrity at all times. As a team, we believe that transparency builds trust, so we default to disclosure in our communications. Each individual executes with excellence, creating an environment of greater alignment and greater autonomy. We win as a team and respect all people to empower everyone to learn from each other, innovate, and grow.

Responsibilities

  • Your first month will be spent getting to know our company and your fellow HackerOnies through our well-organised and fun onboarding process called H.A.T.C.H
  • You will set up your development environment, get a feel for our engineering processes, and embark on a journey to fully understand the domain you will be working with
  • By day 30, you will have met most of your fellow Engineering HackerOnies, paired with other Software Engineers, developed a strong understanding of our codebases and Security Management products, and be prepared to start hands-on coding
  • By day 60, you will be involved in building a meaningful part of one of the projects and will have become more connected with our community and various stakeholders
  • By day 90, you’ll have impressed your colleagues with your technical contributions and earned trust and credibility within your squad and the whole Engineering team by presenting your progress during our review/demo sessions
  • Work together with stakeholders, designers and product leaders to deliver outcomes tied to team goals and roadmap
  • Build, ship and maintain highly available, performant and durable features, focused on (but not limited to) hacker-facing areas of our platform
  • Drive predictable delivery by identifying and removing blockers, managing dependencies, and reducing rework through better planning and technical decision-making
  • Be a part of cross-squad initiatives and contribute to shared platform improvements that increase team throughput and quality
  • Mentor and be mentored by other engineers; help onboard and guide IC1s and IC2s
  • Contribute to CTEM and agentic work, including:
  • Building AI-assisted and agentic workflows where systems can reason, use tools, and collaborate with humans (with appropriate guardrails)
  • Using data and evaluation to guide iteration (quality metrics, feedback loops, experiments, and post-launch monitoring)
  • At first, a tech-savvy person who likes to work with people and teams
  • Willing to learn from Senior and Staff Software Engineers
  • Owner of your progress as an individual
  • You bring 5+ years of software development experience within a modern SaaS environment
  • You’re proficient in dynamically typed, OOP languages such as JavaScript, Python, Ruby or similar languages
  • You have 5+ years of practical SQL experience (PostgreSQL preferred).
  • You’ve worked extensively with cloud platforms (5+ years, with a preference for AWS) to enable scalable, automated infrastructure.
  • You have hands-on experience with ReactJS or similar modern front-end frameworks.
  • You’ve led end-to-end technical projects through all phases of the software development lifecycle, and are now looking to apply that experience toward building intelligent, automated, and AI-enhanced security products.
