# Lead Security Engineer at Prelim

- **Company:** Prelim
- **Location:** New York, NY
- **Employment:** full-time
- **Work type:** remote
- **Posted:** 2026-09-16
- **Last confirmed live:** 2026-10-17

## Job description

## About Prelim

Prelim builds digital account-opening infrastructure for community banks and credit unions. We've sustained over 100% ARR growth for four consecutive years on seed funding, and our platform sits in the critical path of how banks onboard their customers. When our system is down, a bank can't open accounts for its customers. We're a small team. You'd be our first dedicated security hire and help define the security program for the next generation of banking.

## What you'll own

- 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. You'll know them cold.

## What we're looking for

- 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

## Nice to have

- Fintech or banking-vendor experience; familiarity with FFIEC, GLBA, or bank third-party risk management
- Experience as a first or early security hire
- Detection engineering / SIEM experience
- Familiarity with core banking integrations or handling of PII/KYC data flows
