Build something special
Avalonia is a small company behind technology millions of developers rely on. The framework is established; the company around it is being built now: product, brand, marketing, documentation and commercial operations. Join early enough to own one of them.
Who we are
Small on purpose, spread across 11 countries
The team has more than doubled in the last year. Engineering is hired wherever the right person happens to live, and works remotely. Operations is being built as a hybrid team in Tallinn. We get everyone together in person when it is worth doing, and protect the hours when people do their best work the rest of the time.
Why now
The technology is established. The company is still early.
Most early-stage roles ask you to build the product, the market and the company all at the same time. Here, the product has had thirteen years to prove itself, and millions of projects already rely on it. What's early is everything else around it.
Join now and you are not betting on an unproven technology and unknown market. You're early to the company, and the people who join now will be the ones who get to say they built it.
Proven
Thirteen years of development, 2.1 million projects and more than 400 million builds in half a year. The framework has already proved itself.
Funded and accelerating
The team more than doubled in a year, backed by a three million dollar open-source commitment from Devolutions and engineering partnerships with Google’s Flutter team and Microsoft.
Still being built
Marketing, commercial operations and the business around the framework are being created now. Entire functions have nobody in the seat yet. You'll be creating the way we work rather than inheriting it.
Why Avalonia
Avalonia runs where software has to work.
Interfaces built with Avalonia are used during emergency surgery. They run on field ventilators deployed in war zones, in systems that manage nuclear fuel, and in defence systems used to coordinate responses. Across healthcare, energy, defence, manufacturing and infrastructure, people make consequential decisions through software built on Avalonia.
In those environments, the user interface is not decoration. It is how someone understands what's happening, decides what to do next, and controls the system in front of them.
Most of the people relying on Avalonia will never know its name. That is the nature of foundational technology. But if it fails, the consequences can be very real.
The documentation has to be accurate. Support has to get to the bottom of problems. Commercial operations have to work when customers depend on us. Marketing cannot make claims the product cannot support. Whatever your role at Avalonia, you are working around technology people trust in situations where getting things right matters.

The work
What you would actually be working on
Not a wish list. Every one of these shipped in the last year, and each of them had one person with their name on it. Only half of them were written in code.
Text and fonts, from the bytes up
Parsing font files directly so text rendering stops depending on someone else’s stack and stays consistent on every platform we ship to.
A documentation site, rebuilt
Restructured for Avalonia 12 with 125% more guides, dozens of pages rewritten to fix real inaccuracies, and traffic that turned a record day into an average one.
Accessibility on Linux
AT-SPI2 brought up from scratch, plus a DBus library of our own, so assistive technology works properly on a platform most frameworks quietly skip.
A product line renamed and repriced
Accelerate became Plus, Pro and Enterprise, and it landed on the same day as Avalonia 12, across every product, page, licence and contract.
AI that touches a live app
An MCP server that lets a coding agent attach to a running application, read its visual tree, and check whether the change it just made actually worked.
A $3 million partnership, told in public
Devolutions fund our open-source development with three million dollars over three years. Telling that story a year in, with real numbers and nothing resembling spin, was marketing work.
Where the work happens
It takes a great deal more than engineers
Avalonia is a commercial business as well as an open-source project. Devolutions fund our open-source development with a three million dollar commitment, and we work with Google’s Flutter team and Microsoft on bringing their technology to new platforms.
At 19 people, marketing isn’t a department you’re joining; it’s a function you’ll help define. The same goes for commercial operations. The next few people we hire are as likely to sit outside engineering as in it.
Our principles
Three things we won't compromise on
Own the outcome
Whoever owns a piece of work sets its milestones and makes the call on when it is ready. Nobody here waits for permission to do the job they were hired for.
Share the context
Good decisions depend on context. We share the priorities, trade-offs and reasoning behind decisions so people can act without waiting for information to trickle down.
Say the real number
All-hands sessions go through revenue, spending and priorities without any spin. You can't be expected to make good decisions from a sanitised picture of the business.
What we offer
Here is what you can expect when you join Avalonia.
Global engineering, Tallinn operations
19 Avalonians across 11 countries. Engineers are hired wherever the right person happens to live. Our operational functions are being built in Tallinn.
Time that is actually yours
We replaced the daily call with a written weekly update, and a meeting needs a reason to exist. Your most productive hours stay unbooked.
Encouraged to go deep
Our regular hack-week is an opportunity to experiment. Linux accessibility, XAML hot reload and live previews in the docs all started there, and all of them shipped.
The tools to do your best work
If something helps you do better work, tell us. Adobe Creative Cloud, JetBrains Rider, AI assistants, specialist software or something we've never heard of. Tell us about it, and we'll pay for it.
Operations
Tallinn is where we run the company
We build the technology globally, but we're building the company in Tallinn.
We're building the commercial and administrative side of Avalonia as a hybrid team in Tallinn, where the company is registered. We've an office in the city, with three days a week together in person, and leadership regularly on the ground. Marketing and commercial operations work from there, and more of the operation will join as we grow the team.
If you aren't located in Tallinn today, talk to us anyway. It\'s a beautiful, compact, English-friendly capital inside the EU, and if that sounds ideal, we will take relocation seriously with you.
Benefits
The practical stuff
These policies come straight from our company handbook.
Time off without games
Take at least 25 days off each year, including public holidays. Need more? Take more. There is no formal approval workflow. Just coordinate with your team and make sure your responsibilities are covered.
Sick leave on trust
If you are unwell, take the time you need to recover, paid, and without doctor’s notes. We assume you are being honest with us.
When life gets hard
Compassionate leave without questioning your relationship status. For pregnancy or child loss, a minimum of four weeks paid, for either parent.
Support beyond the salary
Emergency financial assistance, salary advances and extended leave when life demands it. No paperwork: if you ask for help, we’ll step up to help.
Learning without a cap
Books have no fixed budget and need not relate to your role. Courses, conferences and certifications are funded, and speaking at them is work time.
€1,500 to meet the team
An annual in-person budget for every Avalonian: travel, accommodation and meals for time with colleagues, wherever makes sense.
The kit to do the job
A MacBook Pro and 4K monitor as standard, at home or in the Tallinn office, plus the peripherals and furniture a proper workspace needs.
Paid for impact, not tenure
Compensation is reviewed when your contribution grows, not when the calendar says an annual cycle is due. Exceptional work is recognised quickly.
Fit
Who thrives here
The principles describe the company. This describes the person, in both directions, because a careers page that only flatters is not much use to either of us.
You will probably thrive here if
- You move without being chased, and tell people what you did rather than ask what to do
- You write clearly, because a company spread across eleven countries runs on writing
- You disagree in the open, including with the CEO, and change your mind when the better argument wins
- You care about craft: yours, and the standard of everything around you
- You would rather own an outcome end to end than manage a team of ten
You probably won't enjoy it if
- You want a playbook, a manager who checks in daily, and a curated list of todos
- You don't enjoy taking ownership and experimenting
- You measure seniority in headcount and reporting lines
- You prefer theory to action
- You need the buffer of process between you and the consequences of your decisions
If the first list reads like a description of you, we would like to meet you.
From the team
In their words
Avalonia is one of the few places where remote genuinely works. Everyone gets real ownership of what they build and a real view of how the company is doing, and that builds trust in both directions.
Yiu LukeTechnical WriterI was given space to work on things that mattered from my first weeks, along with the context to understand why they mattered. The mix of autonomy, trust and direct feedback got me productive quickly.
Javier SuárezSoftware DeveloperI am trusted to make the right calls on my own work. That autonomy is what lets me focus and actually deliver something I am proud of.

Where we need people right now
Growth
Estonian based roles are employed directly by AvaloniaUI OÜ and based at our Tallinn office three days a week. We use an employee of record service for roles outside of Estonia.
How we hire
Step 1
Apply
A person reads every application, and we give feedback wherever we can.
Step 2
Intro conversation
Twenty minutes on your motivations and your questions, in both directions.
Step 3
Interview with the leadership
Forty five minutes on your experience and your vision for the role.
Step 4
Role-specific assessment
A role-specific interview or a take-home project. Substantial take-home work is paid.
Every person we hire has a noticeable impact on a team this small, so we choose carefully. The process is there to understand how you think, how you work and whether this is a place where you can do some of your best work.
Don’t see the perfect role?
We hire when we meet the right person, not only when a role is posted, and we hire well beyond engineering. Tell us which part of the work you would want to own, and show us something you have done.
