High agency, clear ownership mindset, and intentional career choices that reflect genuine commitment to craft. A strong side-project portfolio demonstrating technical depth and sustained curiosity. Experience working at fast-growing, early-stage startups is a strong plus.

Practical experience is valued; formal credentials are not required. Eligible and willing to work on-site in Stockholm, including relocation if needed. Visa sponsorship is not available.

Compensation & Benefits Salary range: $80,000 to $120,000 USD annually , plus equity. The salary and equity mix is negotiable, with flexibility for exceptionally senior candidates. Visa sponsorship is not available.
