About the Company

Our client is the pioneer behind a cutting-edge, AI-powered composable platform that brings together Integration, Data Management, Analytics, and Orchestration in one seamless, cloud-native SaaS solution. Their technology empowers business, technology, and data teams to accelerate digital transformation, deliver actionable insights faster, and extend the value of legacy systems.

 

About the Role

As a Front-End Engineer, you will be instrumental in building intuitive, high-performance web applications. You will work closely with product managers and backend engineers to deliver seamless user experiences on the company’s core platform. The tech stack is modern and robust, with React, TypeScript, and Next.js at its core, and plenty of room for innovation in UI architecture and performance optimization.

This is a hands-on engineering role with the opportunity to influence design systems, technical decisions, and the evolution of the product’s front end.

We are looking for a strong Lead Frontend Engineer who will take full ownership of the frontend part — someone who will actively contribute to the product rather than wait for detailed instructions. 

This person should be able to assess the current frontend setup on the client side, propose a clear roadmap and effort estimation, and determine whether the current team capacity is sufficient or if additional resources are needed. 

The client hasn’t had a dedicated frontend developer before — the existing UI was built by backend engineers and is currently in poor shape. There’s a high chance the codebase is messy and will require a thorough review. The Lead will need to analyze it and propose a solid plan for refactoring or rewriting the frontend properly. 

That’s why we need a proactive, hands-on leader and driver who can take initiative and guide the frontend direction with confidence. 

Key Responsibilities
 

• Design, develop, and maintain front-end web applications using React and TypeScript.
• Work with the product and engineering team to develop wireframes and prototypes.
• Define and improve UI/UX guidelines and best practices for the platform.
• Build and maintain reusable components and contribute to the design system.
• Work as part of a cross-functional squad, delivering new features using agile methodologies with minimal guidance.
• Work with MongoDB and other data stores.
• Write and maintain unit and end-to-end tests using Jest and Playwright to ensure quality.
• Review PRs and provide feedback to maintain high-quality code and engineering best practices.
• Participate in technical discussions and contribute to platform improvements.
• Stay up to date with the latest web technologies and advocate for best practices.

Your Knowledge & Experience

• 5+ years experience in modern web development.
• Experience working with design tools such as Figma to create wireframes and prototypes.
• Strong proficiency in TypeScript, React, and npm.
• Experience with web frameworks like Next.js and Express.js.
• Familiarity with component libraries like ShadCN, MUI, Tanstack, and building out custom design systems.
• Deep understanding of CSS frameworks like Tailwind, responsive design, and accessibility principles.
• Strong knowledge of REST APIs, component-driven architecture, and front-end state management.
• Experience working with MongoDB or other similar Document NoSQL data stores.
• Knowledge of cloud platforms, such as GCP and AWS.
• Strong testing mindset with hands-on experience using Jest, Playwright or similar testing frameworks.
• Worked within an agile environment (Scrum, Kanban, etc).

Soft Skills: 

• Excellent communication and presentation skills
• Energetic & driven
• Innovative
• Resilient
• Insightful
• Creative
• Problem solver
• Sound judgement
• Analytical
• Capacity to learn

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings
• Other location-specific benefits

N-iX is a global software development service company that helps businesses across the globe create next-generation software products. Founded in 2002, we unite 2,400+ tech-savvy professionals across 40+ countries, working on impactful projects for industry leaders and Fortune 500 companies. Our expertise spans cloud, data, AI/ML, embedded software, IoT, and more, driving digital transformation across finance, manufacturing, telecom, healthcare, and other industries. Join N-iX and become part of a team where your ideas make a real impact. We are committed to continuous innovation and are now strategically leveraging Generative AI to significantly enhance our Software Development Life Cycle (SDLC) productivity.

We are looking for a skilled Gen AI Adoption Lead (Engineering Productivity) to join our team.

We’re building a small, sharp team to reinvent how software gets built—using GenAI to augment the SDLC end-to-end. You’ll lead by doing: pilot use cases, wire tools into real workflows (CLI/IDE/CI), and teach teams to ship faster with higher quality. No hype—measurable impact.

You will be joining a core, 6-person GenAI Adoption group inside Engineering. We partner directly with delivery teams to make AI a daily habit (coding, tests, reviews, docs, DevOps). Think: Copilot/Claude/Cursor + scripts/agents + CI hooks. We’re remote-first across the EU/EE (PL/UA welcome).

Key Responsibilities:

• Embed AI in the SDLC: turn “nice demo” into daily CLI/IDE workflows and CI steps.
• Run fast pilots: pick 2–3 high-ROI use cases per account, ship in weeks, measure, scale.
• Build glue + agents: small tools, prompts, and automations that actually stick.
• Coach by pairing: live code-along, short playbooks, internal demos.
• Measure outcomes: baseline → deltas (cycle time, PR throughput, defects, time saved).
• Keep it safe: model/provider choices, data handling, guardrails, policy basics.

Requirements:

• 5+ years as hands-on engineer (Java or .NET great; Python/TS welcome).
• Daily driver of GenAI coding tools (Copilot, Claude Code, Cursor, Code LLMs).
• Comfort with CLI/IDEs/CI (GitHub/GitLab, JetBrains, VS Code, Bash), and wiring APIs.
• You’ve shipped at least one AI-assisted workflow (tests, codegen, review bot, docs).
• You can teach: workshops, pairing, short guides. Clear English, straight talk.
• Pragmatic about quality & security (you know when AI output is not production-ready).
• Bonus: AWS/Azure, Kubernetes/Terraform, prompt patterns, lightweight agent orchestration.

You may not like the role if:

• You prefer slideware over shipping.
• You avoid terminals and CI—this is engineer-first, not tool theater.
• You want certainty. We iterate, measure, and change course fast.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
• Education reimbursement
• Memorable anniversary presents
• Corporate events and team buildings
• Other location-specific benefits
