About Blaze

We're building the world's first agentic marketer to rewrite the rules of who gets to win in business. Our mission is to level the playing field for every team of one—so your success is determined by your courage, creativity, and commitment, not your existing wealth, power, or connections.

Blaze Autopilot is the first AI that actually does marketing for you. It doesn’t just generate ideas—it runs campaigns end-to-end. From strategy to content creation to posting across every major channel, Autopilot acts like a full-time marketer on your team, learning and improving every week.

Blaze serves tens of thousands of small businesses. But we’re just getting started on our journey to a million customers and beyond.

We’re looking for a full-time, senior performance engineer who will make sure every interaction with our platform feels instant, reliable, and effortless. In this role, you’ll shape how both our applications and infrastructure scale, uncover what slows them down, and build the foundation that lets us deliver a seamless experience to every user as our customer base grows.

About the role

We're looking for an experienced Performance Engineer to make sure our systems are fast, reliable, and built to scale. You’ll design and run performance tests, pinpoint bottlenecks, and collaborate with product and engineering to optimize how our applications behave under real-world conditions. This is a hands-on role where your work directly impacts customer experience and our ability to grow.

As a Performance Engineer at Blaze, you’ll ensure our products feel fast and seamless for every user, building the systems and practices that let us scale without sacrificing experience. If you’re excited about solving real engineering challenges in a startup where every improvement you make is felt across the company, this is the role for you.

Specifically you'll:

• Design and execute performance, load, stress, and scalability tests across our systems and applications

• Monitor system performance in staging and production environments, using metrics to identify bottlenecks and opportunities for improvement

• Partner with engineers to debug performance issues and implement fixes at the application, database, and infrastructure levels

• Establish best practices for performance testing, monitoring, and tuning across the engineering org

5. Have professional maturity. You stay calm, assume good intent, and keep work fun - while building strong, easy relationships.
