Security & Infrastructure Engineer

Security & Infrastructure Engineer

Hybrid · Ghent (BE office)

Polysense builds operational intelligence software for food manufacturers. Companies like Agristo, Lotus Biscoff, and La Lorraine Bakery Group already run on it.

Our customers are large enterprises, and those customers run security reviews before they buy. Not just a policy PDF, but real cyber security and resilience throughout the solution and our organisation. That's the technical bar this role exists to clear.

As our Security & Infrastructure Engineer, you own two things.

• First, the hands-on technical side of getting us to security compliance. Owning Vanta, building out ISO 27001, then SOC 2: real controls and real infrastructure, not just legal paperwork.

• Second, as part of the Product & Engineering team you become the team’s go-to owner for IT/infra needs, fixing root causes instead of bandaging symptoms.

You set the standard and build from scratch. Breaking, testing and learning as you go. You’ll also act as a sparring partner and advisor to our CTO/Co-founder who you’ll report to directly.

Mission: build the technical security foundation that keeps Polysense viable with large enterprise customers, and become the owner who keeps engineering's operational load from piling back up. 

💼 What you'll be doing 

1. Security & compliance, hands-on Own Vanta, ISO 27001 first, then SOC 2. Real controls, not a rising percentage. Audit and legal are not your main focus.

2. IT & infrastructure, on call Engineering's front line: scaling our GPU infra for model training, a new internal tool that needs deploying, VPN access requests. You fix why it keeps happening, not just the ticket.

3. The longer-running stuff once the fires are out: kill wasted spend, fix what keeps breaking, automate what shouldn't need a human.

4. Systems over tickets: You own the systems, not just the tickets. Building increasingly agentic and AI-native solutions so you're not the bottleneck for everything.

5. The calls nobody else will make: New tools, vendor picks, prioritization decisions the team keeps circling on, you advise and decide together with the CTO/Co-founder. 

Key point: you're not an auditor or a compliance lawyer. You're the technical builder behind the checkbox. 

💪 What you bring Background & Experience

• Genuine CS/engineering aptitude, you can script, debug, find root causes, and you're comfortable on the command line.

• Hands-on sysadmin experience, you've kept systems running before. No formal networking credentials required.

• Real exposure to ISO 27001 and/or SOC 2.

• AI native approach, setting up AI agents to handle certain tasks for you is your default mindset.

• Startup or scale-up background (or a lean team inside a bigger company) you know what it's like to own something broad and undefined.

• Roughly 2–5 years of relevant experience, generalist rather than narrowly scoped.

• Nice-to-haves: cloud architecture (Azure), a compliance platform like Vanta, IT/networking fundamentals: cabling, wifi, firewalls.

• Not required: audit-leading or legal-compliance experience.

Mindset & way of working:

• Resourceful, low-context: you chase your own answers and don't need much hand-holding to get moving.

• Actively looking for more, not less: you're not coasting in a comfortable mid-level role; you want the harder, messier version of this job, compliance and hands-on infra both.

• No ego, team-first: you fit an engineering-driven team that communicates plainly and works well under pressure, without needing to be the loudest voice in the room.

There's real room to grow here. Deeper into compliance/audit ownership, or toward senior infrastructure. We're not locking you into one lane.

🌟 What success looks like 

✓ You own Vanta: you understand what "100% complete" actually means, not just the dashboard number 

✓ ISO 27001 is moving toward certification; SOC 2 is queued up next 

✓ By day 60, fewer requests are landing on engineering leadership directly

✓ By day 90, the root causes behind those requests are shrinking too, not just getting patched faster 

✓ Tool and vendor decisions get made and stick, instead of stalling in endless debate 

🌟 The Perks, What's in it for you?

• Real ownership: you're not waiting for sign-off, you're building the thing.

• Freedom to innovate: Experiment, create, and bring your bold ideas to life.

• Ambitious no-ego team: People aim high and dare to fail. They also pick up work wherever needed, even if it "isn't their job".

• Competitive salary in line with industry benchmarks and full benefits including a company car.

• Shared growth and real impact: Take ownership of your projects while co-developing the future of Polysense with the team.
