At Jamf, we believe in an open, flexible culture based on respect and trust. Our track record and thriving work environment all stem from the freedom we grant ourselves to get the job done right. We take pride in helping tens of thousands of customers around the globe succeed with Apple.
The secret to our success lies in our connectivity, while operating with a high degree of flexibility. Work-life balance remains our priority while feeling connected is important to maintain our strong culture, achieve our goals, and thrive as #OneJamf.
This role is offered as a hybrid in Brno, Czech Republic. We are only able to accept applications for those based in the Czech Republic or who have sponsorship to live and work in the Czech Republic.
What you’ll do at Jamf:
At Jamf, we empower people to be their best selves and do their best work. The Jade team makes sure that only enrolled, company-managed devices used by authorized users can access business-critical resources over the network. We own Jamf's DNS infrastructure: gateways that enforce security policies, content filtering, and threat blocking in real time across hundreds of millions of daily requests. We also own a distributed key-value store built on Raft consensus for low-latency reads at edge locations. Everything runs on AWS EKS.
This role is also about shaping how we build. We're rethinking our workflows and engineering culture around AI-assisted development, and we need someone who wants to be part of that - not watching from the side, but helping steer it.
What you can expect to do in this role:
Our stack currently includes Go and Java, but we don't expect you to know both (or either) on day one. What matters is that you've worked seriously in at least one strongly typed language and can pick up another when the job calls for it. With the AI tooling available today, that ramp-up is faster than ever.
The main challenge is scale. We're preparing for significant traffic growth, and you'll help figure out what needs to change and make it happen. You'll also spend time improving how we run things: dashboards, alerting, runsheets, synthetic monitoring.
On top of that, you're joining a team that's actively changing how it works. We use Claude Code daily. You'll help us get better at it - building judgement about when AI tools help and when they don't, working closely with product, and raising the bar on our craft.
You'll join the on-call rotation once ramped up (team of 6, one week each, low noise). This is a Senior Software Engineer role, and we expect impact beyond the team - cross-team initiatives, knowledge sharing, being a voice in broader conversations.
#LI-Hybrid
What we are looking for:
- Solid experience in at least one strongly typed language (Go, Java, C++, C#, Rust, or similar).
- System design thinking. Distributed systems, failure modes, consistency trade-offs, what breaks at 10x scale.
- Critical thinking and good judgement. You question assumptions and make reasoned calls under uncertainty.
- Ability to learn fast. New language, new framework, new domain - you figure it out. This matters more than what's on your resume today.
- Real experience with AI-assisted development (Claude Code, Copilot, or similar). You've used these tools in your actual work, you know their limits, and you're ready to help the team use them well.
- Readiness for a challenging period. AI is changing how software gets built. We want someone who sees that as an opportunity and wants to help the team build the skills that count: agency, judgement, close collaboration with product.
- Clear communication. You explain technical decisions plainly, give and take direct feedback, and work across teams.
- Backend experience at scale. High-throughput services, observability, operational excellence. Familiarity with DNS, Kubernetes, or AWS is a plus, not a requirement.
- No ego. Small team, lots of trust, everyone learns from each other.
Why Jamf?
- We are progressive but laid back. You are free to be a yourself and work how you work best. Here, you manage your own day and your own work style.
- You will have the opportunity to work with a small and empowered team where the culture is based on trust, ownership, and respect.
- With hybrid and remote roles, we offer an open flexible culture based on respect and trust.
- Benefits are a critical part of the “whole employee experience”. Our benefits package includes 30 days of paid time off, 3 paid days to volunteer, Benefit Plus cafeteria, Multisport Card, and more.
- Visit our Jamf Engineering blog to learn more about the innovative projects our team is working on and what we learn from each challenge we solve. A blog written by engineers, for engineers at medium.com/jamf-engineering

We are a team of free-thinkers, can-doers, and problem-crushers. We value humility and the relentless pursuit of knowledge. Our culture flows from a spirit of selflessness and relentless self-improvement - driving both personal growth and collective progress throughout our company. We unite around common goals while respecting personal approaches, believing that fulfilled individuals create a thriving, vibrant workplace.
Our aim is simple: hire exceptionally good people who are incredibly good at what they do and let them do it. We provide the support and resources to let everyone be their authentic, best selves at work, at rest, and at play. We are committed to supporting the continual improvement of Apple in the workplace, the organizations that rely on them and the people who keep it all running smoothly.
Above it all, waves our banner of #OneJamf – and the knowledge that when we stand together, we accomplish so much more than we could alone. We seek individuals who share this unwavering journey toward growth to join us in our quest for constant improvement.
What does Jamf do?
Jamf extends the legendary Apple experience people enjoy in their personal lives to the workplace.

With Jamf, customers are able to confidently automate Mac, iPad, iPhone and Apple TV deployment, management, and security – anytime, anywhere – to protect the data and applications used by employees in the workplace, students learning in the classroom, and streamline communications in healthcare between patients and providers.

We’re building a visual-first testing platform that simplifies how apps are tested. No endless configs, no fragile Selenium logic. We’re talking real automation — and yes, we’re already looking at AI, computer vision, and LLMs to help generate tests in the future.
Behind the scenes, we run a flat team structure, we experiment a lot, and when something doesn’t work, we fix it. No middle layers, no gatekeeping.
You’d be joining early — we just silently launched alpha version of the product — with full opportunity to shape the product and how we build it.
Your toolbox (the stuff we actually need):
- Solid .NET Web Services experience (this is core)
- You’ve built REST APIs, not just used them
- You want to be part of refinements, not wait for hand-offs
- You’re curious, technically solid, and ready to grow
Your angle (what you bring on top):
No one’s perfect, but if you bring two or more of these, we’ll get excited:
- deep performance optimization and scalability experience (.NET)
- monitoring or observability know-how
- security mindset
- background or interest in computer vision / AI
- a feel for UX/UI that goes beyond dev perspective
You might also know (bonus points):
- PostgreSQL, Redis, S3
- Entity Framework, Next.js, React
- Microservices, GitHub Actions, Kubernetes, CI/CD
How we work:
- No managers
- Teams that decide together
- Code meets product meets reality
- We listen, challenge, and improve — quickly

One of our terminal-based product teams is looking for a new junior/medior teammate!
We build end-to-end features across client, backend, and cloud, touching everything from Java/Android terminals to Svelte-based web clients and Scala services. Our product spans technologies, but our mindset stays the same: we apply core principles, not dogmas.
Whether you’re a seasoned junior or a mid-level dev, what matters the most is your technical curiosity, eagerness to learn across domains, and motivation to keep pushing the team and yourself forward.
We work hybrid, and ideally, we’d like someone who can drop by our Ostrava office at least once every two weeks. That said, flexibility is part of the deal.
WHAT WE OFFER:
- A manager-less structure. No micromanagement. No status pyramids. Everyone has a say, and it counts.
- Full-stack experience. You can shape the product from UI to backend and cloud orchestration. We’re not boxed into roles.
- A “stuff diving” mindset. We work with what’s needed, apply the right principles, and carry lessons across technologies.
- Freedom to grow. If you like exploring new things like DevOps, functional programming, frontends, whatever we’ve got space for it.
- Peer-driven culture. We build things together, review each other’s code, and hold regular knowledge-sharing sessions.
WHAT WE EXPECT FROM YOU:
Must have:
- Java proficiency, or solid experience with another OOP language and a willingness to switch
- Genuine interest in functional programming. Scala is our backend language of choice, and we’ll help you get there
- Readiness to drive things forward, whether it be through tech exploration, pair programming, or sharing your insights
- Ability to switch context and stay comfortable outside a single tech stack
- Curiosity, responsibility, and a desire to get things done, not because you’re told, but because it excites joy
Nice to have
- Experience with any functional or multi-paradigm language: Scala, JavaScript, Python, etc.
- DevOps awareness: Kubernetes, ArgoCD, Bamboo, shell scripting
If you love learning, solving real-world problems, and aren’t afraid of crossing technical boundaries, let’s talk.
