## Job description

Reaktor's tech community is looking for lead developers to join us in Turku.

As a lead developer at Reaktor, your job is to work with the full software development lifecycle, help your team succeed, and deliver results

Your daily tasks include:

- Being the first point of contact for the client when it comes to technical questions or the quality of the delivery
- Working together with the client’s tech and business teams: facilitating collaboration between different stakeholders to ensure quality delivery
- Implementing new features that require changes to front-end applications, back-end servers, and/or databases, knowing what is needed from infrastructure to support the team's work
- Improving the team's ways of working by empowering them to discover optimal workflows and enabling a healthy work-life balance among team members
- Building relationships with the client to ensure future collaboration
- Assisting the team in adopting and following agile practices

You are  an experienced developer who enjoys facing technical challenges and is at home providing clarity in ambiguous situations

To thrive in this position, you’ll need:

- Experience on a broad spectrum (back end, front end, and ops). Usually, to be successful in this role at Reaktor, we've noticed it's good to have a minimum of eight years of relevant work experience
- Solid understanding and experience of agile project management principles
- To have both previous team-lead and consulting experience
- Experience working with several client stakeholders to solve complex problems
- Previous experience with at least one common server-side programming language. Currently, many of our projects are built with TypeScript/JavaScript and Node.js. But, Java/Scala/Kotlin, Clojure, and Python are also used
- Strong knowledge of at least one common client-side language and framework. We often use TypeScript/JavaScript and React on our web app projects and Swift, Java/Scala/Kotlin, or TypeScript/JavaScript React-native on mobile
- Relevant skills to create new backend services and tweak CI/CD pipelines when the project requires
- Know-how on databases (e.g., PostgreSQL)
- Fluent verbal & written English skills
- To be willing to work in a hybrid setup, where you work with your team at the office or at the client premises

Why join us? For two decades, we’ve been developing qualities and capabilities for adapting, reacting, and supporting change – building Reaktor to hold up in a fast-paced environment while ensuring the well-being of our people.

While working at Reaktor, we’ll provide you with:

- To be able to impact how you work. Together with the client, your team chooses the approach, technologies, and methodologies you think will work best in any given situation
- A community with as much support as your heart desires
- A team that’s not only experienced but considerate as well – they all want you to succeed
- A sustainable work-life balance and support for your daily life outside of work. (e.g., free moving day, Reaktor car share, sick child care services, office space to use for your private events, etc.)
- An opportunity to grow as a professional. In addition to the day-to-day work, we offer internal training courses, community events, and 15-minute coffee breaks to discuss hot topics in tech and design
- A possibility to take part in more extended academy-like studies like Cloud Academy.
- 300+ hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of (and sometimes inside) office hours. Many of these are supported by Reaktor

Diversity, equity, and inclusion Together, we are committed to making Reaktor an environment that embraces and values all of our employees for the whole of who they are. We encourage applicants from all backgrounds to apply, knowing that studies show that members of underrepresented communities don’t apply for jobs unless they fully satisfy all of the requirements. If you're thinking twice about applying for this reason, we invite you to send us your application anyway. You could be just the person we're looking for.
