About Kleos

Kleos is a global payroll platform helping companies hire and pay teams in 242 countries. We're scaling our B2B marketing engine and building the operational backbone to support it.

The Role

You'll own the systems layer of our go-to-market: CRM architecture, marketing automation infrastructure, data quality, attribution, and reporting. This is a hands-on builder role, you'll design and run the machinery that our campaigns, lifecycle programs, and sales handoffs depend on. You'll work directly with the Head of Marketing and be one of the first dedicated hires on the marketing ops side, so you'll have real ownership from day one.

What You'll Do

• Own HubSpot administration end-to-end: object architecture, properties, lifecycle stages, lead scoring, workflows, and integrations.

• Build and maintain the marketing-to-sales pipeline: lead routing, MQL/SQL definitions, handoff SLAs, and feedback loops.

• Design and maintain attribution and funnel reporting (attribution, campaign ROI, pipeline contribution) across HubSpot, GA4, and our analytics stack.

• Set up and optimize tracking infrastructure: UTM governance, conversion tracking, form and event instrumentation.

• Automate repetitive GTM processes with workflows, cold outreach and, where useful, tools like Clay, Claude.

• Manage data quality: deduplication, enrichment, segmentation health, database compliance (GDPR).

• Partner with lifecycle, paid, events marketing teams to make sure campaign infrastructure (audiences, triggers, suppression logic) is reliable and measurable.

• Document processes so the operation scales beyond you.

What We're Looking For

• 3–5+ years in marketing operations / revenue operations / GTM operations at a B2B SaaS company

• Deep, hands-on HubSpot expertise (Marketing Hub + Sales Hub; Enterprise experience strongly preferred) — workflows, custom objects, reporting, integrations.

• Strong marketing analytics skills: comfortable defining metrics, building dashboards, and diagnosing funnel problems with data.

• Experience with GA4 and Google Tag Manager; familiarity with attribution tools (e.g., Dreamdata) is a plus.

• Experience with enrichment/automation tooling (Clay, n8n, Zapier, or similar) is a strong plus. Also open to automate work with LLM tools.

• Systems thinker who can also just get things shipped, we're a small team and you'll build a lot yourself.

• Bonus: experience in payroll, EOR, HR tech.
