Senior Full-Stack Engineer

You don't want to ship features into a void — you want to see managers roll out what you built before lunch. As Senior Full-Stack Engineer you build the interfaces and backend systems that make the Firstier Shield suite usable, fast, and reliable.

Firstier is in the company-building stage. There is no legacy codebase to untangle and no ticket factory: you ship production features across Shield Control, Shield Web, and the supporting API layers, working directly with the security and product leads.

What you'll own

• You ship production features across Shield Control, Shield Web, and supporting API layers.
• You own frontend and backend quality for admin workflows, policy configuration, audit views, and deployment tooling.
• You collaborate with security and product leads to turn enforcement logic into clean, trustworthy user experiences.
• You keep the platform fast and reliable — performance and polish are features, not afterthoughts.
• You help set the engineering culture: code review standards, tooling choices, and how quality is defined here.
  
  

What you bring

• You are a strong generalist engineer who ships polished product — frontend, backend, and infrastructure without friction.
• You care about UX quality in technical tools: an audit view nobody understands is a bug.
• You write TypeScript and modern React comfortably and can design the API behind the screen.
• You make pragmatic engineering decisions and document the why.
• You thrive with direct ownership and short feedback loops over process and ceremony.
  
  

What we offer

• Work where you create leverage
  
  

Every role is remote-first with optional onsite collaboration in Munich — plus focused in-person team weeks for planning, customer work, and product decisions.

• Direct founder access
  
  

You work with the founder office on strategy, tradeoffs, and speed. There are no layers between your work and the decisions that shape the company.

• Real ownership
  
  

Lead roles here are not coordination jobs. You own outcomes, shape the roadmap, and influence how the company is built.

• Top-tier equipment and AI tools budget
  
  

We fund the setup you need for serious work and expect the team to use the best tools available — understanding the category from the inside is part of the job.

• Flexible travel support
  
  

We make room for customer visits, pilot support, and team sessions whenever they create real momentum.

• A global operating posture
  
  

Firstier is built for teams working across markets, regulators, and time zones — from the middle of Europe, in your customers’ time zone.
