Security Engineer

Interfere is building the self-healing layer of the internet: software that detects broken product experiences, understands what caused them, and helps teams fix them before users notice. Modern teams have logs, dashboards, traces, and session replay. They still find out about too many problems from their users. We exist to close that gap for engineers, PMs, designers, and founders who care how their product actually works in the real world. The product surface is large. The category is still being defined. The people who join now will help shape how the company grows. We’ve raised $5.1M from Y Combinator, Vercel Ventures, Hummingbird, Designer Fund, and others. We’re in person in New York City. **THE OPPORTUNITY** We’re hiring our first Security Engineer to own security at Interfere across our product, infrastructure, internal systems, and vendors. This is a new function, and you’ll own it from day one. This is a hands-on role. You’ll write code, harden our infrastructure, ship security features, and run our compliance programs. We ingest customer telemetry, connect to customers’ code and tools, and sell to engineering teams that run security reviews before they buy, so security is part of the product and part of how we win deals. You’ll work directly with our founder and engineering team, with significant autonomy over how security is run. The systems you build now are the ones the company will scale on, with room to take on more responsibility, and eventually build a team, as Interfere grows. **WHAT YOU’LL DO** - **Own security end to end.** Be responsible for application, infrastructure, and internal security: code review, secrets, dependencies, cloud permissions, service accounts, and production access. - **Build and harden our infrastructure.** Work on the platform itself: infrastructure as code, deploy pipelines, access controls, and the systems that keep customer data isolated and safe. - **Ship security as product.** Build the security features customers rely on, like access controls, data masking, and workspace security settings, and make sure they hold up in practice. - **Find and fix vulnerabilities.** Run vulnerability management, threat modeling, and pentests, and take findings from discovery to verified remediation. - **Keep us audit- and customer-ready.** Own incident response, vendor and integration reviews, our SOC 2, ISO 27001, and GDPR programs, and the security reviews that come up in sales. We expect you to own outcomes, not hand off reports or tickets. **WHO WE’RE LOOKING FOR** We’re looking for someone who’s already owned security at a technical company and is ready to build the function from the ground up. - **You’ve owned security in production.** You’ve been the person responsible for security at a SaaS, developer-tool, or similarly technical company, ideally at an early stage. - **You’re an engineer first.** You write production code and infrastructure, automate checks, and fix issues yourself instead of filing them. - **You work across the whole surface.** You’re comfortable with application security, cloud and identity security, vendor risk, incident response, and compliance. - **You have good judgment.** You find the real risk fast, recommend a practical path, and know what needs action today and what can wait. - **You make the team faster, not slower.** You explain risk and tradeoffs clearly, and push back when it matters without becoming a default blocker. **COMPENSATION & BENEFITS** - Base salary: $160,000–$250,000 per year - Equity compensation - Direct exposure to leadership, engineering, and customers - Significant ownership over how security is built and run at Interfere - Opportunity for career progression and increasing responsibility as Interfere grows You’ll be joining early, doing real work from day one, and helping build a security function that will be core to how Interfere grows. If that sounds like you, we’d love to hear from you. Visa sponsorship is not available for this role.
