Employees in this role work closely with our frontend, quality assurance, and product teams to create a user experience that fosters Postis' high standards.

You will work primarily in Spring Boot and PostgreSQL and deploy to a globally distributed infrastructure hosted on Amazon Web Services. An ideal candidate would also have experience with queuing services, in-memory data stores, WebSocket management, monitoring and alerts, and continuous integration techniques.

We're scaling quickly, recruiting teammates who share our core values, know how to get things done, and add to our very driven culture.

What you will do

  • Develop software solutions by studying information needs; conferring with users; studying systems flow, data usage and work processes; investigating problem areas; following the software development life-cycle
  • Determine operational feasibility by evaluating analysis, problem definition, requirements, solution development and proposed solutions
  • Document and demonstrate solutions by developing documentation, flowcharts, layouts, diagrams, charts, code comments and clear code

  • Knowledge of cloud computing platforms (AWS, Microsoft Azure)
  • Deep knowledge of concurrency, resiliency, and caching
  • Self-driven personality: you are highly motivated to deliver top-tier solutions with minimal guidance
  • Learning mindset: eager to learn about and use new frameworks, languages, and APIs; admit mistakes and use failure as a learning opportunity
  • Adaptability & flexibility: you are able to adapt quickly to changes in business requirements and work in an agile environment
  • Critical judgement: you smartly separate what must be done well now, and what can be improve later; exhibit bias-to-action and avoid analysis-paralysis

  • Rich health plan (medical, dental, vision)
  • Annual development budget for activities of your choosing (training, dedicated workshops, participation in industry events & conferences)
