Senior Backend Developer (Java)

 This is a remote position Poland-wide with the possibility to work at our office based in Wroclaw. 

Developers at Duco work as part of an agile, cross-functional, empowered engineering team. Each autonomous team owns the destiny of their part of the product and makes decisions jointly, alongside representatives from Product, Sales and other customer advocates. They don't just "code up" stuff that someone else specifies.  Because where’s the joy in that?

You could be developing our award-winning reconciliation platform to meet future scaling requirements. Or building out our data prep (ingestion and transformation) product. Or maybe both, by helping refactor common components to a fully service-oriented architecture. 

Technologies:

In terms of technologies, the ‘heavy lifting’ is mostly done in Java; web frameworks in use include Ruby on Rails and Spring Boot; and we utilise both MySQL and Clickhouse databases. It all runs in a cloud infrastructure which leverages Kubernetes, Docker and Helm.  We also care very much about the developer experience, so we invest in the right tooling. Recently, that’s included projects involving Gitlab, Bazel and automation testing frameworks.  

And across the stack, you should expect continuous diversification and development. We improve through innovation, so we welcome the impetus that new eyes and fresh perspectives can bring.

In return, you’ll get a worthy reward package: 

• A base salary in a range 22 000 - 28 500 PLN, reviewed annually
• B2B contract is an option
• A success-sharing bonus scheme, so we recognise and reward your effort
• Unlimited annual holiday, because we trust our people to manage their own time off
• Flexible working options: you can choose to work from home, at the office, or both - whatever is best for you
• Flexibility around working hours, as long as you’re delivering what’s needed
• Annual allowance to help you make the best of your home working environment
• Enhanced family leave provisions
• Personal learning and development opportunities (we dedicate budget for this)
• Spot rewards, so we can say thanks when you do a really great bit of work
• Referral bonus if we hire someone great who you’ve recommended to us
• Employee of the Month and Employee of the Year awards
• 4 Volunteering days off that can be used flexibly based on the employee’s choice of initiative
• Private medical care packages: individual, partner or family 
• Multisport card
• Life insurance package
• % deductible costs scheme (AKUP) - employment contract

• Designing and building new features, new services and new technologies 
• Ensuring the code you and your team deliver is supportable and highest quality
• Working with Product Owners to understand customers and scope out work
• Performing code reviews for others, and having your code reviewed by your peers
• Teaching and mentoring less experienced colleagues

We would love to hear from you if you have:

• A keen interest in writing resilient software that scales
• Extensive experience with Java or other statically typed languages
• Experience with one web framework (Spring Boot or Ruby on Rails)
• Working knowledge of SQL and/or relational database concepts
• Experience in splitting application from monolith to microservices 

Not essential, but it would be great if you have the following:

• Experience with AWS
• Solid experience with one dynamically typed language (e.g. Ruby)
• Aptitude with CI and CD pipelines (GitLab preferred) 
• Experience with Kubernetes deployments (Helm) 
• Exposure to Ubuntu Linux
• Knowledge of Javascript, Typescript and a front-end framework (React)
