Why VXA

VXA is building the AI-native marketing workspace. The new infrastructure for how creative work gets done.

We help brands automate content creation, performance insights, and campaign execution through our intelligent, on-brand AI systems.

From fast-growing startups to global names, teams already use VXA to create campaigns that perform, in minutes instead of days. Traction is strong, the roadmap is ambitious, and we’re just getting started.

We’re a small, senior team backed by some of the best investors in the Nordics, operating from a beautiful office in Östermalm, Stockholm.

The Role

As a Founding Engineer, you’ll shape both our product and the company itself.

You’ll work directly with the founder, own critical systems, and help define the technical foundation for a product that will scale globally.

What You’ll Do

• Build core product features end-to-end using Next.js, Supabase, and Vercel
• Integrate multi-model AI workflows via Mastra, OpenAI, and Anthropic
• Collaborate tightly with design and product to ship beautiful, high-impact experiences
• Shape architecture, tooling, and infrastructure as we scale
• Help set the tone for engineering culture, velocity, and product quality

What We’re Looking For

• Strong frontend skills (Next.js / TypeScript) and comfort working full-stack
• Curiosity and hands-on experience with AI integrations (LLMs, agents, frameworks)
• Product-minded builder who values clarity, speed, and clean UX
• Low-ego collaborator with strong judgment and bias for action
• Based in or aligned with CET hours

Our Stack

Frontend: Next.js, TypeScript

Backend: Supabase

Cloud: Vercel, Supabase

AI: Mastra, OpenAI, Anthropic, other LLM providers

Tooling: GitHub, internal agent workflows

Why This Role Matters

VXA is early, well-funded, and moving fast.

You’ll join a small, founder-led team where your decisions directly shape the product, the company, and the market we’re defining. We value execution, taste, and precision over process. You’ll have real ownership, and meaningful equity, in a company backed by top Nordic investors and trusted by leading brands.
