Application Security Engineer Opendoor - Miami, FL, US Onsite/Remote

Software Engineer

Miami, FL, US / Onsite/Remote

Founded in 2014, Opendoor's mission is to empower everyone with the freedom to move. We believe the traditional real estate process is broken and our goal is simple: build a digital, end-to-end customer experience that makes buying and selling a home simple, certain and fast.

About the Role (Hybrid 4 days onsite, 1 remote) All Levels

You're interviewing for Opendoor, not any specific team. We don't slot you into a team on day one, rather once you're in, we match you to where you'll have the most impact and the most fun.

This isn't a role for everyone. We choose hard mode. We're process-light, high-trust, and we don't put artificial boundaries between you and the work. You'll be expected to understand how your piece connects to the product and communicate at that level. We don't have project managers, we don't have scrum. We do reviews, proposals, demos, and trust.

What We're Looking For

You ship. You pick the boring solution when boring is right and the novel one when it isn't. You measure twice and cut once, but you also know when "good enough and shipped today" beats "perfect next quarter."

You think in first principles. You have opinions on architecture, distributed systems, and the tradeoffs between technologies. You can speak to the constraints, tripwires, and heuristics that come with operating in a complex and high touch environment. You've formed these opinions through your experiences, not from a book.

You're language-agnostic. We care about deep expertise, not loyalty to a specific stack. If you've done the most impressive work of your career in a language or framework we don't or haven't used, we want to hear from you.

You default to AI. You've already integrated modern AI tools into your daily workflow. You use them to move faster, not as a crutch.

You communicate well. You write clear design docs. You give useful code reviews. You push back on bad ideas without making it personal. You can explain a technical tradeoff to a non-technical stakeholder and actually land it.

You believe in what we're building. Not hype, conviction. You see the opportunity in what we're doing and you want to be part of finishing it.

You have fun. We stay human when times are hard. We all know what we're trying to accomplish, and the task is daunting, but we're all in it together.

What You'll Do

• Build production systems that real customers and real money depend on • Own features end-to-end, from design through deployment and beyond • Lead and participate in technical design reviews • Use AI tools daily and help push them further than anyone else in the industry • Review code, mentor teammates, and raise the bar on everything around you • Bridge the gap between infrastructure and product

Qualifications

• Deep software engineering experience with a track record of shipping production systems others depend on • Strong fundamentals in at least one general-purpose language; comfortable picking up new ones • Experience with relational databases and the ability to reason about performance at scale • Based in or willing to relocate to Miami, Toronto, or Seattle

Interview Process

We move fast. Typically:

• Recruiter phone screen (15 min) • A 60 minute technical deep dive interview to understand a past problem or project you've worked on • Two 60 minute pairing style technical reviews

We're not running these to see if you can finish a problem under pressure. We want to know what it's like to work with you. Before each interview you'll receive an email on what to expect from each one.

Not a perfect fit on paper but clearly excellent?

Apply anyway and tell us why in your cover letter. We value T-shaped people. If you have deep expertise in an adjacent area and a strong point of view on how it applies here, that's exactly the kind of person we want to talk to.

At Opendoor our mission is to tilt the world in favor of homeowners and those who aim to become one. Homeownership matters. It's how people build wealth, stability, and community. It's how families put down roots, how neighborhoods strengthen, how the future gets built. We're building the modern system of homeownership giving people the freedom to buy and sell on their own terms. We've built an end-to-end online experience that has already helped thousands of people and we're just getting started.
