Original job description

About Flexport:

At Flexport, we believe global trade can move the human race forward. That’s why it’s our mission to make global commerce so easy there will be more of it. We’re shaping the future of a $10T industry with solutions powered by innovative technology and exceptional people. Today, companies of all sizes - from emerging brands to Fortune 500s - use Flexport technology to move more than $19B of merchandise across 112 countries a year.

The recent global supply chain crisis has put Flexport center stage as we continue to play a pivotal role in how goods move around the world. We are proud to have the support of the best investors in the game who believe in our mission, solutions and people. Ready to tackle global challenges that impact business, society, and the environment? Come join us.

What You'll Do

Architecture & strategy
Define security architecture for Flexport's products and services, and set the patterns and reference implementations that make secure-by-default the path of least resistance.
Lead security engineering reviews for the highest-risk product features, and set the bar for what "good" looks like in reviews you don't personally run.
Build and scale the security champions program and product security training that extend your judgment into teams where you can't be in every review.
Design-time & review
Lead domain-specific threat modeling and attack surface analysis across Flexport's product surface, not just individual features.
Partner with engineering leadership to resolve the design tradeoffs that a senior engineer would escalate.
Vulnerability management
Set the bar for how the team triages, reproduces, and prioritizes bug bounty submissions and internal security reports, and step in on the hardest or highest-severity cases.
Drive remediation of systemic classes of vulnerability, not just individual findings.
Developer enablement & leadership
Own the security services and tooling consumed by product teams across our global infrastructure.
Mentor other engineers on the team, and act as the authoritative technical voice on product security across engineering leadership.

You Should Have

Typically 2–5 years of experience in product/application security or software development with a security focus - we care more about what you've built than the exact number. If you meet most of this, apply; we'd rather see your work than filter you out on a résumé line.
Strong grasp of web application security principles and common attack vectors (e.g., OWASP Top 10)
Proficiency with application testing tools such as Burp Suite, OWASP ZAP, or browser developer tools
Working knowledge of at least one modern programming language (e.g., Ruby, Java/Kotlin, TypeScript/JavaScript, Python) and at least one major cloud provider (AWS, GCP, Azure)
Comfortable with security on-call rotation and picking up work across security disciplines when needed

Nice to Have

Hands-on experience with bug bounty platforms
Hands-on experience with SAST tools (Cycode, Semgrep, Snyk, or similar)
Experience with cloud infrastructure security and container technologies
Participation in CTF events or open-source security projects
Familiarity with threat modeling frameworks and secure SDLC best practices
Interest in contributing to internal developer security training programs

How We Work

We're in the San Francisco office regularly to whiteboard and ship together
We stay closely aligned with teammates on other continents via Slack, video, and async docs
We have the latest hardware and software, including frontier AI models on day one
We're agile, but not dogmatic - the team decides how it works best

Why This Role Is Special

Massive leverage: the conventions and champions program you build are multiplied across hundreds of engineers who never talk to you directly.
Broad authority: you set the architecture other reviews are measured against, rather than being the one measured.
You're part of PSI: the platform, security, and infrastructure teams work hand in hand, and security is treated as infrastructure with real engineering quality bars, not a policy function.

Where you'll work

This role is based in San Francisco, and we have a strong preference for candidates who are there or willing to relocate - we're deliberately building this team in one place. Relocation support is available for the right candidate.

Investing your time with Flexport means having immediate impact, all over the world. You're empowered to do what's best for everyone and trusted to make the right decisions when and where you need them. Join our collective of entrepreneurs and improve the world's experience in global trade.

The range displayed on each job posting reflects the minimum and maximum target for new hire base salary for the position in the posting's respective region. Our salary ranges are determined by role, level, and location. Within the range displayed, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant education and / or training. Base salary is just one part of our total rewards package at Flexport, which also includes bonus, equity, and comprehensive benefit offerings such as medical, dental, and flexible time off.

Commitment to Equal Opportunity

At Flexport, our ability to fulfill our mission of making global commerce easy and accessible relies on having a diverse, dedicated and engaged workforce. All qualified applicants will receive consideration for employment regardless of race, color, religion, sex, national origin, age, physical and mental disability, health status, marital and family status, sexual orientation, gender identity and expression, military and veteran status, and any other characteristic protected by applicable law.
