Job description

Are you an experienced hands-on Lead Developer with strong expertise in the eCommerce domain? In this role, you'll bring extensive knowledge and practical experience to the team, helping evaluate, implement, and scale leading headless commerce platforms.

We are looking for a Lead Developer to join our Elisa Consumer Webshop development team.

We expect you to actively contribute to development alongside the team. In this role, you will help develop Elisa’s consumer webshop, elisa.fi/kauppa. Our technology stack is diverse: while Java and React remain our primary technologies, we are evolving our architecture towards a composable, headless commerce approach.

As a Lead Developer, your primary responsibility will be to design flexible, robust, and scalable webshop solutions. You will work closely with architects and development teams to drive technical direction, coordinate implementation, and provide guidance that ensures high-quality, maintainable outcomes.

Together with the team, you will refine new features, break requirements into manageable user stories, maintain and improve the codebase, conduct code reviews, and contribute to test automation and DevOps practices. We continuously experiment, analyze data, and develop new capabilities with a strong customer focus.

We see generative AI as an important part of modern software development, and experience or interest in applying GenAI tools in day-to-day development work is considered an asset.

You will join a talented and multicultural team that values collaboration, agile ways of working, and high-quality software engineering. You will thrive in this role if you enjoy working closely with others, mentoring fellow developers, and providing constructive feedback through code reviews. We expect you to understand the importance of testing and documentation as integral parts of software development.

You are curious, proactive, and eager to understand both the codebase and the broader technical landscape. You take ownership of challenges, drive solutions forward, and communicate effectively with both technical and non-technical stakeholders.

What do we expect from you?

• Several years of experience in modern composable commerce development and solution architecture.
• Proven experience designing and building enterprise-scale webshops on modern cloud-native eCommerce platforms.
• Strong expertise in composable commerce principles and API-first (MACH) architectures.
• Experience integrating enterprise-grade, AI-driven search, product discovery, merchandising, and personalization solutions.
• Solid hands-on development experience with technologies such as Go, Java, JavaScript, and React.
• A collaborative mindset and experience working effectively in agile development teams.
• Understanding of web accessibility and SEO best practices.
• Experience with modern software development practices, including DevOps, CI/CD, and AI-assisted development.
• Fluent English communication skills are required.

Our technology landscape includes Java, Maven, JavaScript, React, Redux, CSS/LESS, GitHub Actions, Kubernetes, Elasticsearch/Kibana, Docker, SQL, MariaDB, MongoDB, Node.js, Contentful, Constructor.io, Conductrics, Google Analytics, Cypress, Robot Framework, and Mocha. Experience with these technologies is beneficial, but we are not looking for someone who ticks every box. More important is your ability to learn new technologies, adapt to evolving ways of working, and help us continuously improve our platform and development practices.

Who are we?

We are Elisa Online Services and Growth - an agile group in Elisa’s Digital Services unit developing online services for our consumer and corporate customers. We are about 100 software professionals in multiple teams and our consumer customer webshop development team is one of those. Elisa provides us a solid foundation to continuously develop ourselves to be even more agile and what we do directly affects all Elisa’s current and future customers so what we do really matters and has value.

What can you expect from us?

• Flexible working culture regarding location and time, but as we believe benefit of face to face meetings, so Elisa expects you to work in average 3 days at the office in every week.
• A position that is important – your work has a great significance for corporate social responsibility!
• A good opportunity to develop yourself and to learn new things
• The best teammates and caring and supporting supervisors
• A long term possibility to have ownership of the webshop solution, commitment to the team and development of the services
• Relaxed working environment with time to develop yourself as well
