Jobs

Limeup is an international company specializing in developing tailor-made digital solutions for clients in fintech, healthcare, proptech, automation and other technology-driven industries. We deliver end-to-end products from initial concept and design to implementation and ongoing support.

We are looking for an experienced Tech Lead (Java + React) who will play a key role at the intersection of technology and business: participating in presale processes, developing solution designs for clients, and leading the technical implementation of projects.

Key Responsibilities

• Participate in presale and discovery phases: analyze business requirements, estimate development efforts, and prepare technical proposals and architectural concepts.
• Develop solution designs and Proof of Concept (PoC) for potential clients.
• Define project architecture and technology stack (Java backend, React frontend, API integrations, etc.).
• Lead developers, provide mentoring, and conduct code reviews.
• Collaborate with clients, product managers, and designers to align on technical solutions.
• Ensure implementation quality and technical compliance of the project.

Requirements

• 5+ years of commercial experience in Java development (Spring Boot, Hibernate, REST API).
• Strong proficiency with React.js and modern frontend stack (TypeScript, Redux, Webpack).
• Deep understanding of distributed systems and microservice architecture.
• Experience participating in presale and solution design activities.
• Ability to explain and defend technical decisions to clients.
• English level — Upper-Intermediate or higher.

Nice to Have

• Knowledge and experience with AI / ML technologies (integration of external AI services, understanding of model architectures and LLM tools).
• Experience with cloud technologies (AWS, Azure, GCP).
• DevOps skills (Docker, CI/CD, Kubernetes).
• Experience managing a distributed development team.

Frontend Engineer – Generative AI + Cloud

We’re hiring for a Generative AI Frontend Engineer to join our team.

This is not a typical frontend role. You’ll work end-to-end, from product ideas to user-facing
implementations, helping shape the next generation of AI-driven troubleshooting tools.
What You’ll Do
● Build and ship user interfaces for generative AI workflows
● Work across the stack: mostly frontend, but with occasional dives into backend
integrations and cloud systems.
● Collaborate closely with the CEO and the rest of our team
● Take full ownership of features - from concept to production.
● Help define the future of how engineers investigate and solve cloud incidents using AI.
Requirements
● Extensive frontend experience - ideally in Vue.js, but React/Svelte/Angular are fine too.
● Strong sense of product ownership and the ability to deliver end-to-end.
● Familiarity with cloud technologies like Kubernetes, AWS, or GCP.
● Bonus: experience with Large Language Models (LLMs) and AI APIs
About You
● You thrive in fast-moving environments with high autonomy
● Ambiguity excites you, not scares you
● You use AI coding agents like Claude Code
● You care deeply about developer experience and usability
● You like building things that other engineers love
