About the role

Lead Security Engineer at Prelim, a YC-backed fintech startup building digital account-opening infrastructure for community banks and credit unions. First dedicated security hire responsible for defining and leading the security program, including secure SDLC, audits, incident response, and governance.

Responsibilities

  • Secure SDLC: dependency scanning, static analysis, security review of high-risk changes, and coordinating annual penetration tests. Teach engineers to catch issues before you have to.
  • Partner with DevOps on IAM, secrets management, network architecture, logging, and detection.
  • Policies, risk assessment, and roadmap. Decide what a company our size and risk profile actually needs, and defend that reasoning to auditors, bankers, and internally.
  • Own security questionnaires, vendor risk assessments, and customer security reviews. Banks conduct rigorous third-party risk management (often against FFIEC guidance).
  • Endpoint management, access reviews, phishing resistance, offboarding hygiene. The unglamorous stuff that questionnaires ask about first.
  • Own SOC 2 Type II end to end: control design, evidence collection, auditor management.
  • Owning incident response, from writing the plan, to running the tabletops, and leading if it's ever real. Banks have breach-notification expectations in their contracts.

Qualifications

  • 5+ years in security engineering, with breadth across appsec, cloud security, and compliance.
  • Hands-on: you can read code, write scripts, and configure cloud controls yourself
  • You've owned or heavily contributed to a SOC 2 audit (or ISO 27001 / equivalent)
  • Experience answering enterprise or financial-institution security reviews.
  • Strong written communication.
  • Judgment about proportionality: you know which risks matter at our scale and which controls are theater
