Job details:
Lexsi Labs is a frontier AI lab building aligned, interpretable, and safe AI systems across LLMs, agents, and structured-data model systems. We work at the intersection of research, product, and deployment, translating advanced AI capabilities into real applications for enterprise environments.
We are hiring a Vibe Coding Engineer to rapidly design and build high-quality prototype applications, customer demo apps, and MVP products that showcase Lexsi’s core use cases in a concrete, working form.
This role is about speed, but not chaos. We want engineers who can move from idea to working application quickly using tools such as Lovable, Emergent, and similar rapid-development platforms, while still applying strong engineering judgment, sound architecture, and reliable implementation practices.
You will build end-use-case-specific applications for both internal and external contexts: customer presentations, solution demos, enterprise workflows, internal product experiments, and fast product iteration loops. The goal is not to create flashy mockups. The goal is to create working apps that are credible, usable, extensible, and often close to production-grade MVPs.
What You’ll Do- Build fast, working applications that demonstrate Lexsi’s core product and AI use cases during customer presentations and enterprise solution discussions
- Use tools such as Lovable, Emergent, and similar rapid app-development platforms to accelerate prototype and MVP delivery
- Create use-case-specific enterprise apps that showcase the outcomes of Lexsi’s solutions in realistic business workflows
- Prototype product ideas quickly to support fast product development iterations, internal validation, and customer feedback loops
- Build both internal tools and external-facing applications with strong usability and functional reliability
- Translate ambiguous product ideas, sales requirements, or workflow concepts into polished, working applications in short timeframes
- Ensure rapid prototypes are built on strong engineering foundations so successful MVPs can evolve into durable product paths
- Work across frontend, backend, workflows, APIs, data integrations, and AI system integrations to deliver complete experiences
- Collaborate closely with product, engineering, research, and GTM teams to identify high-value use cases and turn them into live applications
- Reuse patterns, components, and architecture primitives to improve prototype velocity without sacrificing maintainability
What We’re Looking For- Strong engineering background with solid fundamentals in application development, backend systems, APIs, integrations, and product architecture
- Proven ability to build working apps quickly, not just mockups or fragile demo code
- Experience using or adapting modern rapid-development tooling such as Lovable, Emergent, low-code / AI-assisted build systems, or equivalent fast prototyping stacks
- Strong product understanding, especially the ability to convert abstract use cases into useful product flows and believable end-user experiences
- Strong conceptual grounding and engineering judgment, with the ability to decide what should be hacked fast and what must be built cleanly from the start
- Experience building MVPs, internal tools, prototypes, or customer-facing applications end-to-end
- Ability to think in terms of productization, not just prototyping
- Comfort working in ambiguity and turning incomplete ideas into clear, executable systems
- Strong ownership and bias toward execution
Strong Bonus Signals- Experience building enterprise apps, internal platforms, copilots, workflow tools, or AI-native products
- Experience taking prototypes into production or near-production
- Strong taste in UX and product flow design for demos and business applications
- Familiarity with enterprise integrations, dashboards, workflow automation, and AI-backed applications
- Ability to operate across the full stack and make good tradeoffs under speed constraints
Success in This Role- customer use cases become working applications, not slides
- internal product ideas become MVPs in days, not months
- prototypes are fast to build but stable enough to be reused and extended
- demo apps clearly reflect the value of Lexsi’s underlying solutions in enterprise environments
- rapid builds accelerate real product development rather than creating throwaway code islands
