Join in on pioneering procurement AI agents
Since 2019, Pactum has been at the forefront of transforming enterprise procurement with groundbreaking Agentic AI. We are not just automating a process; we are leading the industry in redefining how companies negotiate and manage supplier relationships. Our AI agents work around the clock, collaborating seamlessly with humans to discover negotiation opportunities and close supplier deals at scale. Trusted by over 50 of the world’s largest enterprises, including Walmart and Rolls-Royce, we deliver tangible value, drive agility, and unlock hidden potential.
Ready to make an impact? Join our passionate, global team and be part of a bold mission: to bring trust, transparency, and automation to every supplier negotiation.
As the first in our field, we address novel challenges with novel solutions. Our platform enables large enterprises to manage and monitor negotiations at scale, effectively saving money, boosting efficiency, and strengthening crucial supplier relationships. We’re built on a foundation of deep decision-making capabilities and cutting-edge innovation, which has allowed us to raise over $100 million in funding, including a Series C of $54 million in June 2025 led by Insight Partners. Our technology is proven—with notable achievements like a negotiation and signing carried out entirely by AI agents in just 87 seconds.
About you
We're growing our engineering team in 🇪🇪 Tallinn, Estonia, and looking for strong Product Engineers to help build the foundational systems behind it.
Your daily adventures will include
• Act as a product engineer, not just a code-writer — you'll think about the customer and business impact of what you build, not just the ticket in front of you.
• Design and build large-scale systems that power, manage, and monitor Procurement AI agents.
• Own problems end-to-end — from architecture to deployment — with real impact on a product still being defined.
• Work in our core stack: TypeScript/Node.js, Postgres, GCP, React.
• Use AI tools (think Claude Code, Cursor) as part of your daily workflow to move faster — we expect you to elevate your thinking with AI, not outsource it.
• Write clean, tested code, ship small increments of product value fast and daily via CI/CD, and collaborate closely with your team.
• Solve problems nobody's solved before — we're in genuinely uncharted territory to define how the Procurement industry can be run with AI agents.
• Work alongside a small, sharp team that shares knowledge fast and helps you grow.
• Read more about Pactum Engineering Team here.
What you bring
• A few years of experience building production-grade software, with a track record of owning complex problems end-to-end — mid-level engineers ready to stretch and senior/staff+ engineers alike.
• A product mindset — you care about why you're building something, not just how.
• Genuine fluency with AI coding tools, and the judgment to know when to trust them and when to override them.
• Comfort with lean product engineering principles, TDD, SOLID, DDD, CI/CD — you don't need convincing, you already work this way.
• Sharp instincts for how your work translates into business impact
• Fluent English, and flexibility for a global, startup pace.
