# Platform Engineer at Hyperbound

- **Company:** Hyperbound
- **Location:** San Francisco, CA
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2026-08-22
- **Last confirmed live:** 2026-09-09
- **Apply:** https://jobs.ashbyhq.com/hyperbound/9179fa2e-8193-4bd8-a789-bdddbdceb95a

## Job description

## THE REALITY

If an 11pm Slack message that says "the integration's down, and the customer demos it to 2,000 reps tomorrow morning" would ruin your night instead of get you moving, don't apply.

You'll own the 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 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.

Sound exciting? Good, we're excited too!

## 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, Vanta, 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 already live in.

On the API side, you own design, versioning, and long-term maintainability end to end. Every internal team and every external developer building against us is building against decisions you made. On the integrations side, you're solving the genuinely hard problems: data consistency across systems that were never designed to talk to each other, rate limits that kick in at the worst possible moment, synchronization that has to hold up when a customer's CRM has a bad day.

You'll work directly with the founding team to decide what gets built next and which partnerships actually move the business, not in a quarterly planning doc, in the room.

What you'll bring:

- Deep experience with API design patterns, versioning, and building for the long haul, not just the next release
- Real fluency in OAuth 2.0, OpenID Connect, and the rest of what it takes to secure data moving between systems you don't control
- Time spent in the weeds of other companies' APIs, enough to know that every SaaS platform lies to you a little differently
- A track record of owning something end to end somewhere that moved fast and didn't have a lot of guardrails

Bonus points if you've been at a startup before, maybe even started one, you've run production systems on AWS with real CI/CD, or you've shipped something you're still a little proud of talking about.

## THE TEAM

We're 45 people, growing rapidly, and our EPD teams care about craft in a way that's hard to fake. We're assembling a cracked team of builders, operators, and hunters. People here have started their own companies before. A few of them used to be competition before they decided they'd rather build with us instead.

We've doubled in size since this photo was taken 6 months ago

We celebrate when we earn it. After our Series A we took the whole team to Bali.

When we hit a real milestone, we mark it properly.

## OWNERSHIP AND EQUITY

You won't have a process shielding you from the outcome. When the integration you built helps close an $800K deal, that's yours. When something breaks at 2am, that's yours too. We think that's the right trade.

Equity here is real. You're joining at an early stage with meaningful equity and real secondary opportunities as we grow. We want early employees to end up genuinely wealthy if this works, and we mean that literally, not as a recruiting line.

## COMPENSATION AND BENEFITS

- Salary: $200,000 to $220,000, based on experience.
- Equity: .15%-.3% Series A
- Health: Medical, dental, and vision coverage
- PTO: Unlimited
- Office: In-office in San Francisco 5 days a week, with daily lunches, plus commuter and parking benefits

## THE INTERVIEW PROCESS

1. Intro call with James, Founding Recruiter
2. Tech interviews with the Eng Team
3. Behavioral interview with Luca, Head of Engineering (15 min)
4. Paid, in-person work trial with the engineering and product team (1 day)
5. References and offer

We move fast, from first conversation to offer in 1 to 2 weeks, and we'll be transparent with you at every stage.

## Equal Opportunity

Hyperbound is an equal opportunity employer. We welcome applicants of all backgrounds, identities, and experiences. We do not discriminate on the basis of race, color, religion, gender, gender identity or expression, sexual orientation, national origin, genetics, disability, age, or veteran status. If you need accommodations during the interview process, let us know and we'll make it work.
