Engineering Jobs in London

In the run-up to securing Series B funding, Xapien is hiring a Head of Engineering to build and lead a high-performing, scalable engineering organisation. Reporting to Shaun O’Mahony, Co-Founder and CTPO, you’ll own the systems, practices, and culture that enable a ~35-person (and growing) product and engineering organisation to deliver reliably, iterate quickly, and partner effectively across the business.

You’ll lead the engineering organisation end-to-end: driving delivery execution, scaling the team, building operational maturity, and championing AI-augmented development practices. You will operate at multiple levels — coaching managers and ICs, owning incident response, and setting the operational direction for Xapien’s engineering organisation. This is a rare opportunity to both build the foundations of a scaling engineering org and directly influence the growth trajectory of an AI-native company.

• Establish lightweight, agile practices that support fast iterations, predictable delivery, and continuous improvement.
• Build delivery management processes (planning, estimation, forecasting) that give product and commercial teams confidence in timelines.
• Own QA and testing practices to ensure quality keeps pace with rapid delivery cycles — including release gating through alpha/beta environments, feature flags, and automated regression testing.
• Implement engineering metrics and dashboards (e.g., DORA metrics) that provide visibility into delivery velocity, deployment frequency, change failure rates, and team health — reinforcing Xapien's identity as a data-driven organisation.

• Create career pathways and coaching frameworks that develop strong engineers and future leaders.
• Develop a workforce strategy that accounts for AI-augmented development — understanding where agentic tooling can amplify output and where human judgement is essential, to build a right-sized, cost-effective engineering organisation.
• Establish engineering-wide standards for code quality, review processes, and technical governance.
• Build observability, incident management, and on-call practices that scale with team growth and deployment frequency.
• Embed DevOps, MLOps, security, and compliance practices into day-to-day workflows.
• Partner with commercial teams to align engineering focus with commercial drivers and business objectives.
• Partner with compliance, security, and data protection stakeholders to ensure engineering practices meet regulatory requirements — particularly important given Xapien's role in handling sensitive due diligence data.
• Facilitate clear communication between technical and non-technical stakeholders, contributing to company-wide planning.

• 5+ years leading multiple cross-functional engineering teams through significant growth, including experience managing managers and scaling delivery, QA, and testing functions.
• Proven experience embedding agile practices, fast iterations, and effective QA/testing processes.
• Built or scaled engineering orgs during high-growth early stage phases (Series A/B).
• Strong background in cloud-native architectures, distributed systems, and modern delivery practices (CI/CD, automated testing, observability).
• Experience building observability, on-call rotations, and incident management practices as engineering organisations scale — reducing MTTR and increasing deployment confidence.
• Comfortable operating at multiple levels — from directly managing ICs and leading incident response, to defining long-term operational strategy and scaling the organisation.

• Proven ability to build, coach, and empower engineering managers to lead their own teams effectively.
• Bonus: Familiarity with AI/ML technologies and their operational requirements, including experience with AI-augmented development workflows.
