Why work here

The mission isn't abstract. The customers are real. The deadlines exist.

NIST published the post-quantum cryptography standards in 2024. The EU AI Act started phasing in obligations in 2025. CNSA 2.0 timelines run through 2033. European banks have to produce DORA evidence right now. Hospitals operating clinical AI agents are inside NIS2 scope.

These are not future problems. They are this-quarter problems for the people you'd build the product with. Quanterios is small enough that everyone you ship next to is shipping directly into customer outcomes, no four-layer-deep approval chains, no abstract roadmaps.

We are pre-Series-A, EU-headquartered, building inside the Plothner Group operating model. We pay competitively, write contracts in €, support hours run on CET / GMT, and we mean it when we say we want a team that lives in Europe and cares about European compliance, not a remote-first catch-all.

Where we hire

Six areas. Senior bias. Open to conversations.

We aren't running an open-roles board today, we are talking to specific people for specific shapes of work. The areas below describe what we're hiring against. If any of them describe you, email us with a paragraph or two about what you'd build.

How we work

Six things you should know before applying.

Senior bias on a small team

Everyone ships into customer outcomes. No four-layer approval chains, no architecture committees that don't write code. The smallest team that can deliver wins.

Written-first by default

Decisions live in documents that survive personnel rotation. We default to writing instead of meeting; meetings exist to resolve specific blocks, not to broadcast.

EU-pinned, in-person quarterly

Day-to-day work happens remotely across the EU. We meet in person every quarter, typically Frankfurt, Berlin, or Zurich, for design weeks, customer days, and quarterly planning.

Customer-led roadmap

Every quarter, the team spends time with two or three real customers. The platform's roadmap moves toward what European regulated buyers actually need, not what an abstract roadmap committee thinks is interesting.

Compliance is also internal

We hold ourselves to the same standards we sell. ISO 27001 alignment in progress, GDPR-by-default in our own engineering, EU AI Act risk-tier discipline applied to our own AI components.

Defaults you can override with evidence

We have strong opinions about how to build, ship, and review work, but every default can be overridden if you bring evidence. Strong opinions, loosely held; engineering is a craft of trade-offs.

Package

Compensation, leave, setup, learning.

Compensation

Competitive €-based salary benchmarked against EU peers
Meaningful equity in a pre-Series-A company
Performance and tenure-based salary reviews

Time off

30 days paid leave per year, in addition to public holidays
Mandatory two-week break per year
Flexible day-to-day hours within CET / GMT support windows

Working setup

Pick your hardware · we cover what you need to do the work
Co-working stipend if your home setup needs supplementing
Travel covered for quarterly in-person weeks

Learning

Conference and training budget per person per year
Books, papers, and certifications covered without negotiation
Internal Quanterios Academy access from day one

We don't publish exact compensation bands publicly. The first conversation includes a frank discussion of comp range based on level, area, and location. We benchmark continuously and revise ranges twice a year.

Process

How hiring actually works here.

No multi-month interview marathons. Practical exercise replaces whiteboard interviewing, and we pay for it. Total wall-clock time from first email to written offer is typically 2–3 weeks.

Email us

Tell us which area, what you'd build, and a paragraph about a thing you've shipped that you're proud of. Code samples, papers, design portfolios, whichever fits the role.

5 minutes

30-minute conversation

Mostly the founder or area lead. We talk about what you'd build, what you've built, and whether the work and the team feel right.

Within one week

Practical exercise

Real work shape. We pay you for it, you pick when to do it, and we use it to talk concretely instead of running fake whiteboard interviews.

4–6 hours · paid

Team conversations

Two or three conversations with people you'd ship next to. Two-way, we're checking fit, you're checking us.

Across one week

Offer · or not

If we both want to move forward, an offer with a written compensation range and start date. If not, you get a real reason and a written summary of what we discussed.

Within 48 hours of the last conversation

Send us a paragraph.

One area you'd work in, one thing you've shipped, one reason Quanterios is the right place. We respond to every serious email within five business days.
