Founding Security Engineer

About The Job

Our mission is to make housing more flexible, affordable, and rewarding for the 110+ million renters in the US. Boom is building a suite of rental financial services, including tenant screening, rent payment reporting, rent reporting-as-a-service, and integrations with major property management systems (PMS).

Opportunity

We're expanding our engineering team to meet the growing demands of our B2B partners and B2C users. Boom handles sensitive consumer data at scale, and we report rent payments to the credit bureaus on behalf of hundreds of thousands of residents.

What You'll Do

• Own our application and cloud security posture across our infrastructure and full stack product
• Run our SOC 2 certification effort (evidence, controls, auditor interface), interface with vendors for pen testing, and prep us for the next compliance lifts like CASA, FCRA, state-specific data regs, and enterprise security reviews
• Build the secure SDLC: threat modeling, security-sensitive code review, SAST/DAST/SCA tooling, secrets management, and dependency hygiene
• Triple, contain, remediate, and run blameless postmortems
• Lead incident response and vulnerability management
• Partner with engineering on identity, access, and data handling for PII, credit, and payment data so secure-by-default is the easy path
• Own customer security questionnaires and represent Boom in security conversations with enterprise property management partners

What You'll Need

• 5+ years in security engineering or application security with hands-on web development experience. Track record securing production web apps and cloud environments, with AWS strongly preferred
• Working knowledge of SOC 2 (bonus for ISO 27001, HIPAA, PCI, GLBA/FCRA). You're ready to own the program, not just contribute to it
• Strong grasp of common attack classes (OWASP Top 10, auth/session, SSRF, deserialization, supply chain) and how they show up in modern web stacks
• Backend-leaning full stack on Ruby (Grape and Sequel) with React/Next.js and TypeScript on the frontend. Comfortable with third-party APIs (OAuth, webhooks, rate limits, idempotency), observability, on-call, real incidents, and Terraform
• You're already running AI coding agents autonomously, including overnight, to ship and drive your own efficiency. Daily Claude Code use is table stakes
• Strong communicator who can explain risk to non-security audiences and push back without slowing the business. Self-starter in a fast-paced, early-stage environment, with empathy for our end users including low-to-moderate-income renters whose financial data we steward

Benefits Of Working At Boom

• Competitive salary with stock options
• Full healthcare coverage (health, dental, vision) including 50% coverage for dependents
• 15 days of Paid Time Off (PTO) per year + 3 sick days + all US federal holidays (11 in total)
• Company-issued laptop/MacBook
• Company-sponsored training & development
• Regular off-sites, retreats, and other company-sponsored events and travel opportunities
