(Senior) Go Backend Developer (m/f/d)

  • justTrack
  • Core
  • Full time
As GO Backend Developer you will join a team of highly committed developers, further developing our tracking platform JustTrack by bringing in a lot of own ideas.

JustTrack development started three years ago and is state of the art. On the backend side, our dominant language is Golang and we heavily rely on AWS services. We are using everything from Athena, Docker, and DynamoDB to Kubernetes and SQS. We are currently processing more than 150,000 requests per minute. All these events get aggregated in a meaningful way and are provided to our app development and marketing teams via the JustTrack dashboard written in React.

Our next big challenge is to make the product market-ready. On the one hand, you will have the opportunity to create new microservices from scratch. On the other hand, you can dig into well-established services that already handle millions of requests per day and help us further scale them.
Key responsibilities:
  • Bring fresh ideas to further improve our high-performance Golang backend (separated over several, globally located data programming centers)
  • Take a leading role in designing and implementing new microservices
  • Further, develop our automated testing via CI pipeline
  • As MySQL comes across limits in many places, let us further establish databases like Redshift and Druid together
  • Work with experts from different technological backgrounds and countries, learn from your highly experienced colleagues and share your knowledge
  • How the optimal candidate may look like:
  • Expert for Go!
  • At least 2 years experience with Golang and in building web applications
  • Basic knowledge of microservices and distributed systems
  • Basic understanding of HTTP protocol, encoding, and regular expressions
  • Optional: Knowledge of PHP, Java, or React
  • Optional: Familiarity with AWS services like DynamoDB, Lambda, and SQS
  • What do we have to offer?
  • Shape the future of our tracking platform JustTrack – Share your creativity, support your ideas with convincing arguments, and make them happen!
  • Highly motivated startup team with strong digital background
  • Startup with a fast-paced environment, strong technical background and inhouse solutions in a great new office (An der Alster)
  • We support visits of company relevant congresses and your further education e.g. with weekly tech talks or German courses
  • Flexible working hours including home office days and 30 days of vacation per year
  • Regular team events, off-sites, and parties. . . as soon as it’s possible again
  • Free drinks and snacks, gym membership, and support for public transportation (HVV-Profi Card)
  • State of the Art Hard- and Software😉
  • Skip writing cover letters. Tell us about your most passionate personal project, your desired salary and your earliest possible start date. We are looking forward to your application!

    We celebrate diversity and are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or Veteran status.

    We’ve got a cool new office in a cool new location. The Alster lake in Hamburg, northern Germany, is one of the city’s incontestable highlights. Right outside the main city center, it’s a key hub for all the city action – and the year-round picturesque photos. Needless to say, that’s why we wanted our office to look out onto these iconic Hamburg scenes.

    At justtrack, our team is built on international talent – with more than ten different nationalities contributing actively to our everyday successes and growth. Our colleagues always tell us how good they feel when they can see their hard work and ideas directly impacting our daily business, and we wouldn’t have it any other way. And because we know how hard our team works, regular team events are an absolute must for us. We’re strong believers in flat hierarchies, flexible working, and achieving that all-important work–life balance.



    We guarantee our colleagues the newest tech stack to support you with your everyday activities, whatever they may be. We also love to keep it playful and fun by organizing hackathons on a regular basis, because what better way is there to exhibit your talent to the whole team (and to eat food with them too)? And with our focus on developing new technologies for our partners and products, it only makes sense that we celebrate every single technology launch. Whether that’s with pizza or beer – or both!
