Informacje o stanowisku

We are currently seeking a skilled Java Developer to join our Product team on a freelance basis. Are you ready to collaborate with a group of talented developers to create well-designed, user-centric applications?

Boldare is an Agile-powered company with nearly two decades of international experience in product development and consulting. The company helps clients redefine their industries by building with them the products their users want. Starting in 2004, Boldare now has about 80 talents spread across Europe. They have built over 300 digital products for clients around the globe – Western and North Europe, the United Kingdom, North America, the Middle East, Southeast Asia, and Australia. 

 Being a Java Developer at Boldare means:

  • You can boost your skills and potential in the type of products that fit you best. We’ve cut product development for stages (prototype, MVP, product-market fit, and scaling).
  • Agile, scrum & lean startup are not just buzzwords – no project managers, a scrum master in every team, and iterative product delivery are standard at Boldare.
  • Self-organization – there are no managers in Boldare, so the teams organize their work by themselves. You’ll be engaged in building the product roadmap, sprint planning, etc.
  • Direct impact on the product & tech stack – our scrum teams are responsible not only for performing tasks but also for proposing technical solutions. You’re the expert here, so we trust in your tech recommendations.
  • Clients are partners – we really care about our relationships with them, and we cooperate as equal partners. There will be no proxies in between your team and the client, so forget about waiting ages for the answer to a simple question ?
  • Face-to-face meetings with clients and the team (which are highly valuable for us). Regular business trips are standard at Boldare. With some partners we meet once a month, with others every six months. The frequency varies, but we care for all team members to participate in onsite meetings.
  • Building a product with our long-term partner PRISMA, a leading European gas trading platform with the mission to secure Europe’s energy supply and enable a green transition for a sustainable future.

    Benefits & development opportunities:

  • Guaranteed work in a product - we hire with a promise of employment, so you dont end up on the bench.
  • Opportunity to meet the client with whom you will cooperate and build the product. Meeting with the client is one of the obligatory stages of recruitment.
  • Joining #BoldareTeam, which is a community of open-minded product builders, eager to share their knowledge and best practices.
  • A lot of internal & external initiatives where developers share their knowledge and best practices (e.g., Tech Talks, Product Development Chapters, webinars, team-building internal events).
  • Great atmosphere and teamwork based on various ways of working face-to-face with your team (at least once per quarter).
  • Flexible working hours and the possibility of remote working – you can work wherever you like! But still, you can always use one of our offices in Cracow, Warsaw, Gliwice, or Wroclaw.

Sounds interesting?
Send us your application, we’re waiting for you! :)
