Own what "good" means in technical hiring, and keep redefining it as fast as engineering changes. This is a level of ownership rarely on offer: you'll be the final word on a standard the whole company depends on.

The mission

OfferZen connects great engineers with the teams where they'll do their best work. This role owns the technical heart of that: being sure an engineer genuinely has the capabilities a role needs.

Companies don't buy our assignments, our tools, or our reviewer network. They buy our judgment. That trust is the whole product, and it holds on both sides: reliable for the companies who hire on our word, and fair to the engineers we assess.

What stays constant is that judgment matters. What changes is everything around it. AI is moving fast, and how we assess engineers has to move with it. This isn't a build-it-once role. It's for someone energised by that constant evolution, who wants to work out how each shift should change the way we evaluate.

Your job is to own that standard: to be the last word on what good looks like and on the hard calls, and to keep it evolving so our yes stays worth trusting.

What you'll do

• Make the final call. When reviewers disagree, a candidate is borderline, or a company pushes back, you make the decision that stands, and senior engineers respect it.

• Own the quality bar. Decide how engineers are assessed, keep the reviewer network calibrated to it, and hold it consistent as the people and the work change.

• Set the product direction and partner with the engineer who builds it. You hold what we assess and why; a Senior Product Engineer owns how it's built. You keep the two aligned through close, honest debate, not requirements thrown over a wall.

• Keep the standard moving. Decide what's worth testing as AI changes engineering: more weight on how someone frames a problem, the trade-offs they defend, and whether they truly understand what they built; less on what AI now does on its own.

• Grow a network senior engineers want to belong to. The reviewer network runs on the time and goodwill of senior people. You protect their experience, sharpen their judgment, and grow the bench, partnering with the operations team who handle the day-to-day scheduling.

• Keep it fair and defensible. As AI regulation around hiring tightens, you own whether the standard itself stays fair, explainable, and non-discriminatory. The engineer builds the safeguards; you own the bar.

• Stay hands-on where it counts. You're in the tooling and rubrics that encode the standard. You don't own the day-to-day engineering, but you're technical enough to earn the respect of the people who do.

What we're looking for

• A senior engineer who has personally assessed a lot of engineers and has strong, current views on what separates a great one from a good one.

• Deep enough technically to be a last word that senior engineers defer to. You don't need to be the deepest in every stack. You need the judgment to make a defensible call and the humility to lean on specialists where they know more.

• You've genuinely updated your view of what "good" means now that AI can write the boilerplate. You have a real answer to: what should a technical interview look like in 2027?

• You can build something people want to be part of. The reviewer network is senior engineers giving their time, and you make it worth their while.

• You can drive a result through an engineer you don't out-code: holding the line on what matters, leaving them room on how to build it.

• You're comfortable being the last word. That's the appeal and the bar. If you want shared cover on the hard calls, this isn't the role.

The stack you'll work across

Our platform spans an AI pipeline (Python, LangGraph) that helps generate and evaluate assignments and interviews, a Ruby on Rails API, and a React/Next.js front end. You won't own this codebase day to day, that's the Senior Product Engineer's seat, but you'll be close to it and hands-on in the parts that encode the standard. You should be technical enough to have real credibility with the engineers building it, and opinions about where it should go.

Your first 3 months

We won't throw you in the deep end. The first three months are for getting deep on how we assess today, where it's strong and where it's drifting, building relationships with the reviewer network and your engineering partner, and forming your own point of view on where the standard needs to go. After that, you're making the calls and setting the direction.

We're also hiring for a Senior Product Engineer to support you in building out the product, until then - you'll be very hands-on with building out the product.
