Tech Lead

Technical Lead 
Intro 
We are looking for a strong Technical Lead to join our team working with a Silicon Valley startup on a mission-critical AI assistant for military vehicles. This product is already actively deployed and used by the Ukrainian Army to support their operations. We are committed to this mission and provide our help to the UA army for free. You will lead the design and implementation of the entire platform (Backend, Frontend, Mobile, Infrastructure), ensuring high architectural standards and code quality for a system that makes a real difference. While our backend stack is primarily Python, we value strong engineering fundamentals over specific languages. If you have deep experience building reliable, scalable systems in other languages (e.g., C#, Java, Go), and are comfortable leading teams and designing robust architectures, you will be a great fit. 
Technologies 
● Backend: Modern Python services and APIs 
● Frontend: Web application in React 
● Mobile: Native iOS/Android + React Native (prototype; stack evolving) 
● Infrastructure & DevOps: Cloud-native platform on Kubernetes with CI/CD 
● AI/LLM: Retrieval-augmented generation and agentic workflows 
● Architecture: Clean Architecture and solid engineering practices Responsibilities 
● Own the technical vision and architecture across Backend, Frontend, Mobile, and Infrastructure. 
● Collaborate closely with AI researchers/engineers to create LLM/RAG solutions and ensure robust, reliable workflows. 
● Lead and mentor engineers; establish engineering standards and review processes. 
● Partner with product and stakeholders to shape roadmaps and deliver outcomes. 
● Ensure platform reliability, security, scalability, and cost efficiency. 
● Drive CI/CD and operational excellence for rapid, safe releases. Requirements 
● Proven experience leading engineering teams and owning system architecture. 
● Strong engineering fundamentals (system design, reliability, security), language-agnostic; Python preferred but C#/Java/Go experience welcome. 
● Experience across multiple domains: Backend services, Web Frontend, Mobile concepts, and Cloud Infrastructure. 
● Familiarity with AI/LLM solutions (e.g., RAG, agents) would be a plus. ● Track record of delivering mission-critical systems with CI/CD and operational excellence. 
● Excellent communication, stakeholder management, and mentorship skills; mission-driven mindset.
