Senior AI/LLM Engineer

About BOND BOND makes Europe's €2 trillion public procurement market accessible to every business. Public contracts are published across hundreds of portals, in dozens of languages, with different formats and deadlines — so most companies never even see the contracts they could win. BOND brings them together in one feed, translates them automatically, and uses AI to match every tender against a company's profile.

Tender discovery is just the beginning. Our vision is a platform that handles the entire path from finding a public contract to submitting a winning bid. We are based in Vienna and backed by the NVIDIA Inception, Microsoft for Startups, and AWS programs, and businesses across Europe already rely on BOND every day.

We live ownership: you are responsible for your projects end to end. No politics, few meetings, direct feedback, and short paths to the founders. Join us to help open one of the largest and least accessible markets in the world.

The role

You will lead the AI side of our product: the systems that read, understand, translate, and match public tenders at European scale. You own features end to end — problem framing, design, implementation, evaluation, and production operation — and you set the bar for how AI work is done at BOND.

What you will do

• Design and ship the AI features at the core of the product
• Own quality: build evaluation practices so changes ship with evidence
• Set technical direction and make build-vs-skip decisions with the founders
• Mentor other engineers and raise the team's AI/LLM engineering craft
• Balance quality, cost, and speed in a product with real users and real scale

What you bring

• 5+ years of software engineering experience, with several years shipping AI/ML-powered products to production
• Strong engineering fundamentals and the ability to own systems end to end
• Sound judgment: you know when a simple approach beats a sophisticated one
• Experience mentoring engineers and driving technical decisions
• Fluent English; German is a plus

What we offer

• Salary: €80K – €110K depending on experience
• Equity: you build BOND, so you should own a piece of it
• Equipment of your choice — whatever makes you do your best work
• Hybrid work from our Vienna office, flexible hours
• Direct collaboration with the founders — no politics, short decision paths
• Regular team events, and coffee, drinks, and snacks in the office
