What Are We Looking For?
We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.
As a Senior Software Architect, you will be tasked with driving the transformation of one of our core systems into a scalable modern microservices architecture and defining the next generation of our platform. In this high-visibility, high-impact role, you will lead an ambitious initiative to break down a complex cloudbased monolithic system, written primarily in Python, into a scalable, multi-tenant, cloud-native set of services (primarily in modern Java for new development; you may also meet Go as a secondary language in newer parts of the codebase). You will collaborate across the SentinelOne engineering organization with multiple engineering and product management leaders to design solutions capable of handling global SaaS scale processing petabytes of data and hundreds of billions of events.
RELOCATION INFORMATION:
We provide relocation assistance (financial & administrative) for those willing to relocate to Prague, the capital of Czech Republic. This assistance is available only for candidates that are already eligible to work in the EU at the time of applying.
Why choose Prague?
A historical yet truly metropolitan city - over 250,000 expats currently account for over 25% of Prague's workforce.
Among many other reasons, Prague ranks as the 12th best city in the "World's Best Cities" report, among the top 10 most livable cities in Europe, and consistently also among the safest cities in the EU and the world.
Similarly, Prague's public transport ranked 2nd best in the world, and Prague Airport was voted the 5th Best in Europe (and airports in Dresden or Vienna are just a direct train away).
Every year, there are new investments in Tech coming to Czechia (incl. Prague) from abroad, new R&D sites are being opened, and dozens of Tech jobs are being created. For many years, Czechia has scored among the very lowest % unemployment rates in the EU, and in Tech, there's a deficit of thousands of employees for the open positions.
We offer you a yearly Total Compensation starting from approx. 3,6 mil. CZK (equiv. of 150.000 EUR/year). The final base salary will be adjusted based on the individual skills and experience of the selected candidate. As part of the Total Compensation, we provide an annual bonus based on both the company's and individual performance (paid in two instalments), and a grant of Restricted Stock Units with a 4-year vesting plan (1-year cliff, then quarterly; stock refresh yearly). In addition to this - we also provide a competitive benefits package, incl. covering English-speaking private healthcare membership for you and your +1, on top of renowned Czechia's free public healthcare.
