What Tailscale does

Remote Work Europe sees the daily pattern of European remote job postings through our Connected job board – the trends this piece describes show up there too.

Tailscale is a mesh VPN service built on WireGuard. In plain terms, it lets you connect computers and devices across the internet as if they were on the same local network, without the configuration pain that VPNs historically required. Individual engineers, small teams, and large enterprises use it to build secure private networks across cloud, office, and home environments. More than 4,000 businesses rely on it.

Tailscale was founded in 2019 by Avery Pennarun, David Crawshaw, David Carney, and Brad Fitzpatrick (the same Brad Fitzpatrick behind LiveJournal and memcached). They built a developer-friendly layer on top of WireGuard that removes the pain of setting up private networks: sign up, install on your devices, and they can talk to each other privately wherever they are. The free tier is generous and popular for personal use; the paid tiers handle teams and enterprise. In 2025 the company raised a US$160 million Series C at a reported US$1.5 billion valuation, explicitly to grow headcount – which is the single most important thing to understand about Tailscale in 2026.

Remote culture: what it’s actually like

Tailscale has been remote-first since founding, and it still is. Its own careers page puts it plainly: most people work wherever there’s wifi, with only some teams (Sales, for instance) popping into an office to sync. There’s no expectation of daily presence and no headquarters-bias baked into the culture. The company is deliberately writing-heavy and asynchronous, which maximises autonomy and focus.

The founding team brings deep infrastructure experience, and it shows – the engineering bar is high, and Tailscale’s public technical blog is genuinely one of the best in the industry. That writing culture isn’t decoration; it reflects how the company actually operates, with clear written communication as the default.

The honest assessment: Tailscale is scaling fast. That 2025 Series C was raised to take headcount from roughly 250 towards 400, and rapid growth changes a company. The writing-heavy, high-autonomy culture that people love is easier to protect at 150 people than at 400, and anyone joining now is joining during that transition, not the earlier, smaller version. There’s also real venture pressure behind a $1.5 billion valuation. None of that is a red flag – but it’s a different proposition from a stable, capped company, and worth going in clear-eyed about.

Hiring in Europe: the details

Countries: Tailscale is North-America-centric and Toronto-rooted. Its careers page states the team is located in Canada, the United States, and the United Kingdom. For European job seekers, that means the UK is the clear entry point; wider-Europe roles are more occasional and case-by-case.

Employment model: Direct employment in the countries where Tailscale has established entities (Canada, the US, and the UK). Arrangements elsewhere are less established, so confirm the model for any specific role.

Timezone expectations: Given the North American centre of gravity, many roles expect meaningful overlap with North American hours even when they’re fully remote. This is the main practical constraint for European applicants – check the timezone line on each listing.

Salary approach: Competitive, benchmarked against strong technology-market rates. Tailscale does not publish a public salary formula, so compensation is discussed during hiring.

Language requirements: English is the working language.

Who they’re looking for

Tailscale is engineering-heavy. Roles span:

  • Software engineering (Go, TypeScript, deep networking and systems work)
  • Site reliability engineering
  • Product management
  • Design (developer-focused)
  • Developer relations
  • Solutions engineering
  • Technical writing
  • Sales and customer success (with technical depth)
  • Operations

The bar is set for high technical ability and clear communication in equal measure. Engineering interviews are demanding – real networking knowledge, systems-level thinking, Go fluency for many roles – but the ability to write clearly and document your work is weighted just as heavily.

What current and former employees say

The praise is about calibre and clarity: a strong engineering team, a genuine autonomy-and-focus culture, excellent internal and public writing, and a product people are proud of. Engineers who want to work on hard infrastructure problems alongside serious peers tend to rate it highly.

The cons worth naming: the pace of growth is the big one – doubling a team stresses any culture, and some of the qualities that make Tailscale attractive today are precisely the ones under pressure as it scales. For European applicants specifically, the North American centre of gravity is a real limitation: outside the UK, roles are thinner, and timezone overlap with North America is often expected. And the high hiring bar means the process is demanding and not fast.

People who thrive at Tailscale tend to be strong, self-directed engineers who write well, enjoy networking and systems problems, and are comfortable working across a North-America-weighted team.

How to apply

Specific tips: Use the product seriously before you apply – the free tier is excellent. Set up Tailscale across your devices, wire it into a homelab or a personal project, and you’ll speak about it differently from someone who has only read the docs. Read the engineering blog: Tailscale’s posts on networking and infrastructure are unusually good, and referencing specific ones shows genuine engagement. If you write a personal technical blog, link to it; if you’ve contributed to open-source networking projects, lead with that. And if you’re outside the UK, check the location and timezone requirements on each role before you invest time in an application.
