Data Partnerships @ ClayWe're looking for a
Partner Technical Engineer to join our Data & Integration Partnerships team. This role owns two mission-critical components of Clay's data marketplace: the technical quality bar for every provider, and the technical readiness of every new partner before they go live.
On the data side, you'll work with the Data team to define our end-to-end testing methodology. This includes building standard test kits and the scoring models that determine which providers are integrated, if they make the waterfall, and their relative ranking. Your testing will serve as a strategic input for margin, coverage, and partner tiering decisions across a 200+ provider portfolio.
On the partner side, you will own technical readiness for onboarding. You'll act as our technical gatekeeper-assessing a prospective partner's delivery method, auth pattern, rate limits, and data structure before commercial discussions begin, and certifying that new partners are truly integration-ready before launch.
You'll work directly with partners like Salesforce, HubSpot, Nooks, and dozens of data enrichment providers, and collaborate closely with Product, Engineering, Partnerships and external partner tech teams.
What You'll DoEcosystem Growth- Act as the technical lead for the partnerships team, joining prospective partner meetings from day 0 to design the joint solution.
- Prototype integration concepts fast enough to answer "can we actually do this?" inside a live partner conversation.
- Design the 'build' partner motion on Clay's public API and MCP [this bullet is vague in the current draft too - one clause on what a working build motion produces would fix it].
- Translate partner and customer feedback into roadmap priorities for Product and Engineering, and give GTM what they need to run RFPs and POCs on newly launched integrations.
Data Quality & Provider Evaluation- Own the evaluation system that decides which providers get integrated, which make the waterfall, and how they rank - the calls that determine what every Clay customer gets back when they run an enrichment.
- Define the end-to-end testing methodology with the Data team: standard test kits, scoring models, and re-evaluation cadence across a 200+ provider portfolio.
- Own the public data tests Clay publishes on phone, work email, and personal email, and keep them accurate enough to defend line by line to a partner who disagrees with their score.
- Turn coverage gaps by geography and data type into a prioritized partner roadmap, so we pursue providers that close real holes instead of adding redundant sources.
- Feed test results into margin, tiering, and badging decisions across the portfolio [add the stakes here if you can share them - e.g. "decisions that move [X]% of enrichment COGS"].
Partner Technical Readiness- Build, then automate, the technical readiness assessment every prospective partner passes before commercial discussions begin: delivery method, auth pattern, rate limits, data structure.
- Score partners at intake and work with Partner Development to unblock or disqualify them early, instead of discovering integration problems after a term sheet [insert current cost: "which today costs us [N] weeks per deal"].
- Scope the integration - endpoints, auth, fields, cost-per-call - before contracts are signed, so engineering inherits a spec rather than a surprise.
- Certify partners as launch-ready and run the pre-launch technical checks.
Post-Launch Ownership- Monitor integration health, API performance, and data quality after launch, and resolve complex issues alongside partner technical teams.
- Write the technical documentation and implementation guides partner developers build from.
What We're Looking ForMust-Haves- 3+ years of experience in a technical role (software engineering, solutions engineering, technical partnerships, or similar) working with partnerships, integrations, marketplace and/or ecosystems.
- Deep familiarity with REST APIs, OAuth, webhooks, and modern integration patterns.
- Experience building data quality frameworks, testing pipelines, or evaluation methodologies.
- Proven ability to navigate third-party APIs and dense partner technical documentation.
- Comfort with data analysis, including the ability to write SQL, build dashboards, and extract insights from messy datasets.
- Excellent written and verbal communication to translate complex technical concepts for non-technical audiences.
- Self-starter mentality with a high tolerance for ambiguity and rapid context-switching.
Nice-to-Haves- Experience running structured technical vetting or readiness assessments for partner integrations.
- Background in data enrichment, GTM tools (Clay!), or the broader RevTech ecosystem.
- Prior experience at a high-growth B2B SaaS company.
- Familiarity with CRM platforms (Salesforce, HubSpot) and modern sales/marketing tech stacks.
- Experience using or building on Clay.
- Prior partnerships or business development experience.
