About the role

Key responsibilities & impact

Own UK-EU revenue and pipeline targets tied directly to closed ARR.
Run full-cycle sales across inbound (PLG-driven developer traction) and outbound motions.
Sell to three ICPs: AI-native startups building agents, enterprise teams embedding AI into existing products, and SaaS platforms embedding StackOne for their customers.
Execute and iterate on the UK-EU outbound motion (account targeting, messaging, sequencing, experimentation).
Run live product demos independently and speak credibly about APIs, MCP, and integration architecture.
Partner with pre-sales engineers on deeper technical validation and enterprise security conversations.
Collaborate closely with Product Marketing to refine messaging for technical buyers.
Help build early UK-EU lighthouse accounts and expansion playbooks.
Track and report on pipeline health, deal velocity, forecasting accuracy, and win rates.

Requirements

What you’ll need

2–5 years of B2B SaaS closing experience with clear evidence of overperformance and rapid progression.
Strong track record of owning revenue targets, not just supporting deals.
Experience in early-stage or fast-growing startup environments.
Experience selling dev tools, APIs, infrastructure, or other highly technical products.
Comfortable selling to engineers, CTOs, and technical founders, and running demos independently.
Exposure to AI/LLM products, agentic platforms, or meaningful hands-on experience with AI tools.
High ownership mindset, bias for action, and comfort operating with autonomy — your GTM partners are US-based, so you'll run your patch without daily oversight.
Nice to have: iPaaS/integrations background, security/compliance exposure (SOC 2, HIPAA), experience selling alongside PLG motions.
Dealbreaker: pure enterprise sales background with no exposure to startup environments.
