Backend Engineer
As a Backend Engineer at BOND, you will design and build the services that power our platform — the systems that collect public tenders from all over Europe, process them, and deliver them to the businesses that can win them. You will work on APIs, data processing, and the machinery behind a product that customers rely on every day, and you will own your work from the first design discussion to running it in production. We are a small team, so your decisions will shape the technical foundation of the company for years to come. You bring solid experience building production backend systems, a pragmatic approach to engineering — simple designs, shipped iteratively, measured honestly — and the ambition to help make a €2 trillion market accessible to every business in Europe. Full-time, based in Vienna.

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 build and own core backend services: the APIs our product runs on, the data pipelines that keep millions of tenders fresh, and the integrations that connect everything together. You will work across the full lifecycle — design, implementation, deployment, and operation.
What you will do
- Design and build APIs and services powering search, matching, and the customer dashboard
- Own data pipelines end to end: ingestion, processing, deduplication, enrichment
- Keep the platform fast and reliable as data volume and traffic grow
- Improve observability, testing, and developer experience across the codebase
- Work directly with the founders on architecture and priorities
What you bring
- 3+ years building production backend systems in a modern language and framework
- Solid database fundamentals — schema design, indexing, query performance
- Experience operating services in production: monitoring, debugging, incident response
- A pragmatic approach: simple designs, shipped iteratively, measured honestly
- Bonus: experience with search or data-heavy pipelines
What we offer
- Salary: €60K – €85K 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
