Security Platform Lead

About the role

You don't want to maintain someone else's architecture — you want to define one. As Security Platform Lead you own the technical backbone of the Firstier Shield suite: the enforcement layer that decides, across browser, endpoint, mobile, and control plane, how AI policy becomes action. Firstier is in the company-building stage. The product is real, the first lighthouse pilots are forming, and the engineering standards you set now will carry the platform through enterprise security reviews and Series A scrutiny. You work directly with the founder office — no layers, no committees.

Responsibilities

• Drive the enforcement architecture behind Shield Web, Shield Desktop, Shield Mobile, and Shield Control — one coherent backbone instead of four loose products.
• Ship enterprise-ready controls without sacrificing the fast, minutes-not-months deployment that wins SMB and mid-market teams.
• Set the technical standard for policy execution, local telemetry, and secure rollout mechanics across every surface where AI risk lives.
• Make the platform credible in security reviews — from architecture documentation to the operational posture buyers and auditors ask about.
• Shape build-vs-buy decisions and technical tradeoffs together with the founder office as the suite expands.

Requirements

• You have shipped security or infrastructure products — not prototypes, but software that operates in production for paying customers.
• You move from architecture to implementation without ceremony: you can design the enforcement model in the morning and review the pull request in the afternoon.
• You care about product ergonomics. Controls that managers cannot operate are controls that do not get deployed.
• You are comfortable owning hard tradeoffs — performance vs. coverage, speed vs. enterprise depth — and explaining them clearly.
• You communicate precisely in English with founders, customers, and future hires; experience in early-stage or company-building environments is a strong plus.

Benefits

• 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.
