About Antithesis:

Antithesis helps engineering teams find and fix bugs that traditional testing methods miss.

Our platform runs entire systems in a deterministic simulation, breaks them in every imaginable way, and provides engineers with root cause analysis and perfect reproduction. The result is faster debugging, more reliable software, and more confidence in what ships.

As AI accelerates software development, the need for reliable verification is only increasing. Antithesis exists to solve that problem.

We are well-funded, deeply technical, and building a category-defining platform for modern software reliability.

The Opportunity

Antithesis is building its partner ecosystem from scratch, and you'll be the one who builds it. You'll own our relationship with AWS and turn it into a repeatable engine for pipeline and revenue, then extend the same playbook to other cloud, data, AI, and ISV partners.

This is a true 0 → 1 role. You'll set the strategy, strike the deals, and get sellers on both sides working together, with real ownership and plenty of room to shape what Antithesis becomes in the ecosystem.

What You'll Do

• Own the AWS relationship. Build executive relationships, a joint business plan, and a clear strategy for co-sell, Marketplace, and cloud commitments.

• Expand the ecosystem. Apply what works with AWS to other cloud platforms, data and AI companies, and ISVs, prioritizing the partners that move the business most.

• Structure and close deals. Negotiate co-build, co-sell, and Marketplace agreements with Legal and leadership.

• Turn partnerships into pipeline. Translate integrations and joint solutions into seller playbooks, enablement, and campaigns that scale across teams and regions.

• Set the operating rhythm. Define KPI scorecards, forecast partner-sourced and partner-influenced pipeline, and run regular business reviews with key partners.

• Connect the dots internally. Partner with Product, Engineering, Marketing, Legal, and Sales to align roadmaps, launches, and events.

What You Bring

• 6+ years in partnerships, alliances, business development, or cloud partner go-to-market

• Hands-on experience building co-sell and joint GTM motions with AWS and other technology platforms

• A record of generating partner-sourced pipeline and working against shared revenue targets

• Fluency in AWS Marketplace, co-sell programs, and cloud commitments

• The ability to turn technical capabilities into clear business value and field-ready plays

• A builder's mindset: commercial instincts, strong communication, and comfort rolling up your sleeves

• Willingness to travel up to 40%

• Bachelor's degree or equivalent experience

Bonus Points

• Experience with Google Cloud, Azure, Snowflake, Databricks, or frontier AI labs

• Experience working with global alliance leaders to turn strategy into field execution
