Principal Product Engineer

Budibase is building the platform for AI-powered operations. Thousands of teams use Budibase to build internal tools, automate workflows, and increasingly deploy AI agents into real operational processes. We re building a future where agents, apps, workflows, approvals, and humans work together to get real work done. We re looking for a Principal Product Engineer to help define that future. This is a high-impact role for an experienced engineer who wants to shape both product and technical direction. You ll work directly with the founders and engineering team to solve some of the hardest problems in AI-powered software: reliability, orchestration, permissions, observability, approvals, integrations, and trust. This is an individual contributor leadership role. While you ll mentor engineers, your primary focus will be technical leadership, architecture, product development, and execution rather than people management. While Budibase is a remote-first company, this role involves close collaboration with the founders on product direction, technical strategy, and platform architecture. We re therefore looking for someone who can spend 2-3 days per week in our Belfast office.

Responsibilities

• You ll help shape the technical foundations of Budibase s next chapter.
• Designing the architecture behind agents, workflows, approvals, and automation systems.
• Building platform capabilities that support reliability, observability, permissions, and governance.
• Improving how engineers build, deploy, and maintain product capabilities.
• Taking ownership of engineering challenges that affect multiple teams and ensuring they are resolved.
• Working across the Budibase builder experience, backend services, integrations, and AI infrastructure.
• Solving technical challenges that directly impact product velocity and customer outcomes.
• Mentoring engineers through technical leadership, code reviews, and architectural guidance.
• Helping define technical strategy across the company.

Requirements

• Have significant experience building and shipping production software.
• Have strong TypeScript and JavaScript experience.
• Have built complex products, platforms, developer tools, workflow systems, or SaaS applications.
• Have led large technical initiatives and influenced technical direction.
• Enjoy mentoring engineers and raising the effectiveness of those around you.
• Can balance technical excellence with product outcomes.
• Are comfortable working through ambiguity and helping define solutions.
• Are excited by AI and curious about how it will transform software development and operations.

You do not need to tick every box. Relevant experience could include:

• Building developer tools, workflow platforms, internal tools, low-code platforms, or infrastructure products.
• Working with AI systems, LLMs, agents, tool calling, MCP, retrieval systems, or evaluation frameworks.
• Scaling SaaS products and engineering organisations.
• Contributing to open-source software.
• Working closely with product teams to shape product direction and strategy.
