Full-Stack Software Engineer

Alex is one of the fastest-growing startups to come out of its YC batch with strong traction. We’re revenue-generating, well-funded, and backed by premier investors with years of runway.

We’re building the future of hiring. Our AI recruiter conducts live job interviews, helping companies get deep hiring signals faster and more efficiently than ever before. Customers love the product - and we’re just getting started.

We’re people who:

• genuinely enjoy solving complex engineering problems

• learn quickly and do what it takes to deliver results

• work really, really hard

• move with urgency

• enjoy and value working together in person in San Francisco 5 days a week

Experience preferred in:

• Javascript (Typescript, React, Node, Next)

• Python

• Cloud / DevOps (Azure, Kubernetes, Docker)

• System Architecture

Alex is similar to a marketplace, as we serve both candidates through the interview experience and employers through a data aggregation and analysis platform. As a hands-on engineer, you will build both consumer-facing and enterprise-grade software with a clear opportunity for growth. Problems that you could work on related to consumer software are:

• How can we bring the average interviewer response latency down to 200ms?

• How can we fine-tune our models to decrease hallucination and help Alex pass the Turing test?

• How will our system architecture change as we scale to thousands more users, concurrently?

Problems that you could work on related to enterprise software are:

• How do we integrate with our customer’s internal hiring systems?

• What’s the best way to present interview results visually and as fast as possible?

• How can Alex expand to coordinating the hiring process end to end?

• And many, many feature requests that need to be built out!

• Take ownership of building the next billion dollar company

• Collaborate with a tight-knit team of talented builders

• Launch products that directly impact people’s careers

• Work with the founding team daily in-person in San Francisco

• Competitive salary and equity

• Health insurance, unlimited PTO, and great company events

If you’ve gotten this far and our culture/tech resonates with you, we want you to apply. Your first conversation will be with Alex, our AI recruiter.
