The hardest security problems we face aren’t policy problems. They’re engineering problems. Supply-chain operators, prompt-injection campaigns, and financially-motivated attackers who turn a compromised dependency into production access are challenges that require engineering solutions. A Product Security Engineer is a software engineer whose specialism is making those attack paths hard, expensive, or impossible. They write production code, build detections that catch real attacks, and harden the systems other engineers depend on.
What you’ll do:
- Engineer defence into the product: Multi-tenant isolation, encryption and key management, IAM modelled as code, application-layer hardening.
- Defend the supply chain: Engineer systems for provenance and integrity, dependency trust, build-pipeline isolation, and third-party risk telemetry.
- Detect, respond, contain: Runtime detection, incident response automation, forensics tooling, and adversary emulation.
- Secure the agentic development surface: Own the security layer of our agent platform, including sandbox boundaries and secure-by-default code-generation patterns.
- Lead the security craft inside engineering: Embed within the engineering team, pair with engineers, and raise the bar through tooling and patterns.
What we’re looking for:
- Several years writing production software on AWS with a track record of defence systems.
- Adversarial instincts and hands-on experience using AI coding agents in production workflows.
- A clear model for how agent harnesses work and threat-modelling fluency.
- An open communicator who raises concerns early and contributes in group discussions.
- A high bar for resilient systems.
Desirable:
- Detection engineering at production scale.
- Supply-chain security knowledge.
- Cloud-native attack patterns on AWS.
- Incident response leadership experience.
- Familiarity with cryptography in practice.
- Experience with large-scale data-intensive systems.
- Observability tooling knowledge.
- Regtech, fintech, or regulated-record experience.
- Scoping red-team and pentest engagements.
What you won’t find here:
- A GRC role with an engineering title.
- A queue of CVE tickets to triage.
- A SOC analyst rota.
- A compliance-automation role rebadged as security engineering.
This role exists to defend our product against real adversaries, not to manage a control library.
Our Tech Stack includes Backend: Go, TypeScript, Python; Frontend: React, TypeScript; Cloud: AWS; AI Infrastructure: AWS Bedrock; Infrastructure: Terraform; Data: Large-scale PostgreSQL, ClickHouse, Turbopuffer; Agent tooling: Claude Code, Cursor, Linear, Codex, Sentry, Grafana Cloud, CodeRabbit, Incident.io.
