Security Research Engineer
$120k - $175kPensar
We are seeking a Security Research Engineer to operate as a hybrid Forward Deployed Engineer and offensive security researcher. You'll be on the front lines of customer engagements — using our open source tool Apex to run pentests, curate and present findings, and stand up our platform inside customer environments. In parallel, you'll drive original offensive and open source security research, and feed everything you learn in the field back into the product so Pensar keeps getting sharper as a pentesting platform.
This role is customer-facing by design. The ideal candidate is equally comfortable in a terminal popping shells with Apex, on a Zoom with a CISO walking through findings, and in a design review arguing for the next product capability.
Key Responsibilities
Customer Engagements & Forward Deployed Work
- Run end-to-end pentest engagements for customers using Apex, our open source offensive security tool
- Curate, triage, and contextualize findings for customer audiences ranging from engineers to executives
- Deliver clear, prioritized write-ups and walk customers through results, exploitation paths, and remediation
- Set up and configure the Pensar platform inside customer environments, including integrations and workflows
- Act as a trusted technical partner for customers throughout onboarding, engagements, and ongoing usage
- Travel to customer sites as needed for kickoffs, readouts, and on-site testing
Offensive Security Research
- Conduct original offensive security research across web, cloud, infrastructure, and AI/LLM attack surfaces
- Develop new exploitation techniques, payloads, and tooling that extend Apex's capabilities
- Build automated testing methodologies for emerging vulnerability classes and attacker tradecraft
- Track the evolving threat landscape and translate it into concrete detections and capabilities
Open Source Security Research
- Lead vulnerability research across high-impact open source projects and ecosystems
- Verify findings, build proof-of-concept exploits, and coordinate responsible disclosure with maintainers
- Contribute patches, advisories, and tooling back to the open source community
- Grow Pensar's reputation in the security research community through publications, talks, and contributions
Product Feedback & Pentesting Roadmap
- Translate firsthand engagement experience into concrete recommendations for the product roadmap
- Partner with engineering and product on capabilities, UX, and automation that make pentesting faster and more reliable
- Participate in architecture and design reviews with a focus on the pentester's workflow
- Help shape Apex's direction as an open source project alongside the internal platform
Compensation
- Base salary: $120,000 – $175,000per year, depending on experience
- Meaningful equity in an early-stage offensive security company
- Final offers calibrated to depth of offensive security experience, the breadth of your research record, and the level you join at

- Bachelor's degree in Computer Science, Cybersecurity, or related field, or equivalent experience
Preferred Qualifications
- Experience with AI/LLM-assisted offensive security or building security automation on top of LLMs
