Platform Engineer

THE REALITY

If an 11pm Slack message that says "the integration's down, and the customer demos it to 20,000 reps tomorrow morning" would ruin your night instead of get you moving, don't apply.

You'll own our public APIs and the integrations that connect Hyperbound to every CRM, dialer, and comms tool our customers already live in. Nobody hands you a fully scoped ticket. You'll decide how the OAuth flow should behave when a customer's identity provider does something undocumented, and you'll be right about it, because you're the expert in the room.

Things will break. A rate limit will get hit at 2am before a big demo. A webhook will quietly stop firing three weeks after you shipped it. When that happens, you're not filing a bug and waiting for triage, you're the one who fixes it, tells the customer what happened, and ships the patch before the next standup.

If that sounds like more responsibility than you've been given before, good. That's the job.

WHAT WE'RE BUILDING

Hyperbound is the Revenue Activation Platform, the agentic operating system for sales. We don't just record what happens on a call, we change what happens next, turning real selling behavior into targeted roleplays, coaching, and workflow changes that make reps better without adding a single layer of management overhead.

We started in 2023 out of YC (S23) and are based in San Francisco. Last quarter we doubled headcount, grew revenue almost 2x, and posted 300% net revenue retention. We've raised $18M total, including a $15M Series A led by Peak XV Partners, alongside YC, Snowflake Ventures, Roble Ventures, and Fellows Fund. LinkedIn, Workday, IBM, and Intel all run their sales teams through Hyperbound. We're SOC 2 Type II certified, support 25+ languages, and help sales teams ramp new reps 50% faster.

THE ROLE

You'll be the architect for two things that have to work perfectly at the same time: our public APIs and the integrations that connect Hyperbound to the tools our customers alrea...
