Lead iOS / MacOS Engineer

At Rox, we believe in empowering people to do their best work.

Our platform supercharges sellers with autonomous revenue agents to do the manual work so they can focus on what they do best: selling. Just as coding agents 10x’d engineering, revenue agents 10x customer work.

We are reimagining the revenue stack by building the world’s first revenue operating system, from the application layer to the system of context. With Rox, humans are evolving to orchestrators while agents manage the end-to-end customer lifecycle.

Rox powers Global 2000 leaders in banking, hardware, construction, and sovereign AI, while serving dominant AI winners like Ramp and Cognition.

Underlying all of this success is a unwavering, shared belief in the mission, with an unreasonable commitment of doing whatever it takes to make it a reality.

Nothing is possible without the world-class team, assembled to redefine how businesses operate.

Members on our team have:

• Founded and exited successful companies

• Held the highest positions at Google, AWS, Confluent, and New Relic

• Won IMO and IOI gold medals

• Published field-defining papers

We’re backed by the best, having raised $50M from Sequoia (Alfred Lin), General Catalyst (Hemant Taneja), Google Ventures, Elad Gil, and Chris Ré.

We are led by founder Ishan Mukherjee — an accomplished entrepreneur with mulitple prior exits who blends deep technical engineering experience from Amazon and Apple with sales leadership experience from his time as Chief Growth Officer at New Relic. You’ll work directly with Ishan and the exec team on high‑leverage product bets.
