Lead GTM Engineer, B4B

Bolt for Business (B4B) sells and services business accounts, from SMBs to Enterprise and Strategic Partners, across 25+ markets in Europe, Africa and the rest of the world. Parts of the sales funnel are already automated, but coverage is uneven across markets and a large share still runs on rep time and manual process. As Lead GTM Engineer, you'll take what already works, extend it end to end, and build an AI-native GTM engine so that growth stops being linear in headcount. This is an engineer-first leadership role: you'll architect and write code yourself, stay technical as the team grows, set direction and lead an existing team. You'll report to the VP of Bolt for Business and can be based in London, Lisbon or Tallinn.

• Own AI and automation end to end across the full B4B commercial funnel (lead generation and enrichment, qualification and closing, onboarding, lifecycle management and retention). Audit what is already automated, decide what to keep, rebuild or retire, and build a prioritised 12–18 month roadmap tied to commercial outcomes such as pipeline per rep, cost per SQL, time-to-first-order, activation and retention.
• Personally design and ship production AI systems, including agentic workflows, LLM pipelines, evaluation harnesses and integrations across Salesforce, enrichment and sales-engagement tools, Looker and Databricks, staying hands-on in the codebase throughout.
• Lead, retain and develop an existing team of AI/automation engineers and analytics, and hire as the mandate grows. Set and hold the technical bar on architecture, evaluation, monitoring and safe deployment, and earn the team's confidence quickly.
• Work directly with sales leads and reps across markets to drive adoption through change management, enablement and process redesign. Instrument everything, run holdouts and A/B tests where feasible, and report impact honestly, including what didn't work.
• Translate technical work into commercial language for market leads, Finance and leadership, and commercial problems into technical specs for the team. Own data quality, GDPR compliance for outbound and enrichment, EU AI Act readiness, and vendor and build-vs-buy decisions.

• Strong hands-on engineering depth (Python, APIs, SQL, workflow orchestration, cloud infrastructure), writing and reviewing production code, with proven experience shipping LLM-based systems that run in production and that other people depend on, such as agents, tool use, RAG and structured extraction.
• Rigorous about evaluation and monitoring: you've built eval sets, measured model output quality systematically, and can explain how you caught regressions before users did.
• Proven experience integrating AI systems into messy real-world business systems (CRM, data warehouse, third-party APIs) and building for heterogeneous markets, including emerging ones, where data quality, languages, regulation and process maturity differ.
• Demonstrated ownership of a GTM or revenue system (CRM architecture, sales engagement, enrichment, marketing automation) or clear evidence of learning a commercial domain fast, plus a track record of taking an ambiguous mandate, framing it, sequencing it and delivering measurable business results.
• Experience managing engineers directly, including performance conversations and retention, and excellent written and verbal English that works with both sales leaders and engineers.

Nice to have

• Experience with MLOps at scale, experimentation and causal inference (holdouts, incrementality) is a plus.
• Awareness of GDPR and EU AI Act requirements, and of how data protection and outbound rules differ outside the EU, is a plus.
• Experience in growth engineering, sales productivity, marketplaces, mobility, fintech or high-velocity B2B SaaS is a plus.
• Familiarity with Salesforce, Looker, Databricks, Outreach/Clay-type tooling or n8n, and additional languages relevant to our markets, are a plus.
