🌐 ABOUT BRAINLAB
Brainlab (CYRANLAB, S.L.) is a deep technology innovation center located at Fira Barcelona Gran Via. We don't observe technology trends — we generate them.
We operate across three high-impact brands:
▸ Tarranix.io — Deeptech photonic computing. Proprietary CYRATRON© 6-state architecture using light polarization.
▸ Brainlaverse.com — Browser-based educational and cultural metaverse. Democratizing immersive access to knowledge.
▸ Corpore Fitness — Science-based rehabilitation gym. Conscious training and injury recovery protocols.
We work at the intersection of generative AI, photonic computing, immersive environments and advanced web platforms. We are, quite literally, riding the crest of the technological wave.
──────────────────────────────
💡 THE ROLE — The evolution of a dying position
The traditional Development Manager role is obsolete.
In a world where a single well-directed AI prompt can replace days of manual coding, the question is no longer "how many developers do you manage?" — it is "how intelligently do you orchestrate AI to deliver software at scale?"
The AI DevOps Prompt Lead is the answer to that question. This is a newly created position, purpose-built for the current technological landscape: a technical leader who produces and orchestrates a team of few AI Prompt Developers each one specialized area (scientific simulations, gaming, performance, 3d modelling, engineery, intranet apps,immersivity, PIC RISC generation,etc) within our corporate Github-like local repository using generative AI as a force multiplier — capable of operating with the effective output of a 100-person offshore development factory with a team of five.
Your core mission: produce, design, govern and automate the entire software delivery pipeline across Brainlab's app ecosystem — from business request to production deployment — with minimal manual intervention and maximum AI-assisted throughput.
Your responsability team will be up to 4 AI prompt developers. Same level as Basis/Administration/Local open source Master and AI engineer. Depending and reporting directly to CEO. Continuos interaction with Business/Marketing/HCM and production stakeholders.
The pipeline you will own:
Business request → Prompt → Code generation → Quality inspection → Testing → push Production
──────────────────────────────
🎯 RESPONSIBILITIES
🔹 Central governance of our GitHub-like local repository that include all software projects across the Brainlab ecosystem: PIC engineery,websites, metaverse environments, mobile apps, self-hosted AI applications, scientific/mathematical simulation algorithms.
🔹 Lead the AI DevOps Prompt department, coordinating up to 4 AI Prompt Developers via tools such as GitHub Projects or Monday.com, providing periodical generated Canva/Claude reports to CEO.
🔹 Design and automate the full CI/CD pipeline: Dev → QA → Production pull/push request flows, custom code inspection workflows, performance benchmarks and automated test suites.
🔹 Detect and implement automations that eliminate manual repetitive work. Use Codex, GPT Claude Code, Terminal, local IA tools and equivalent AI toolchains as primary development instruments.
🔹 Manage simultaneous projects, developments, modifications and production incidents across Tarranix, Brainlaverse and Corpore Fitness.
🔹 Automate migration of internal/external projects language-agnostic from external cloud providors to our local host-kubernetes server and database maintain open source local corporate philosophy.
🔹 Build and maintain automated daily and weekly reporting to the CEO on the full app landscape status.
──────────────────────────────
🖥️ TECHNOLOGY SCOPE
The ecosystem spans multiple stacks. The expectation is not mastery of all — it is the ability to use AI as a language-agnostic execution layer: understanding architectures and directing AI tools to generate, inspect and deploy quality code in any required language.
Python · React / React Three Fiber · WebGL · Docker · Caddy · Nginx · GitHub Actions · Linux / Bash · Claude API · Codex · SQL / NoSQL · C++ · Mobile Apps · MEEP / Scientific computing · Monday.com
──────────────────────────────
✅ REQUIREMENTS
▸ Degree in Computer Science, Software Engineering, Telecommunications or equivalent. Master's degree or specialisation courses in Artificial Intelligence — highly valued.
▸ Practical experience in DevOps using tools such Github, Gitlabs, Monday.
▸ Working knowledge of server and network administration, Linux environments, terminal-based operations, and installation/configuration of open-source tools.
▸ Practical experience with both relational (PostgreSQL, MySQL) and non-relational (MongoDB, Redis) databases.
▸ Genuinely current with the latest generative AI developments — not as a hobby, but as a professional discipline. You follow model releases, toolchains and prompt engineering advances as a first priority.
▸ Leadership capability: coordinate teams autonomously, define workflows, set quality standards and maintain delivery velocity.
▸ Automation-first mindset: instinctive drive to automate any process that runs more than twice. Manual repetitive work is fundamentally incompatible with this role.
──────────────────────────────
⚙️ OPERATIONAL STANDARDS
This role operates under high-performance productivity standards, actively monitored through AI algorithms to ensure output quality and consistency. Person must be proactive, disciplined and not reactive, person must account at least 4 hours of max productivity prompt/code per day that is audited live.
→ Personal mobile phone use and non-work distractions are restricted during productive hours.
→ Facilities may not be left during working hours except in justified emergencies.
→ Manual repetitive work is formally prohibited. Every recurring process must be scripted, automated or AI-delegated.
→ Automated daily and weekly reporting to the CEO on the full app ecosystem status is a non-negotiable deliverable of this role.
