Backend Developer - Java / Kotlin / Python

hyperexponential

We are a tech scale-up on a mission to reimagine technology to transform analytical decision-making, helping our customers make smarter decisions faster. Our SaaS platform, hx Renew, allows users to build and deploy mathematical models that can harness the power of weird and wonderful datasets using open source languages such as Python. 

Engineering at hyperexponential

Our engineering department is a melting pot of some of the brightest (and kindest!) engineers in the industry.

The level of complexity of hx Renew requires a highly technical, true engineering mindset so an output of this is a deeply creative, innovative environment where we push technological boundaries, both through our work and our regular (and sometimes irregular!) hackathons.

Your Mission

2024 has been a big year for hyperexponential. Our profile is growing rapidly, and our customer base with it. We have tonnes of exciting features to develop and we want to deliver more of them in parallel, sooner, safer, than we've ever done before. To make sure we're set for the future we're going to be looking at all our systems, refreshing most of them and reworking the rest to get us ready for anything. It's a deeply exciting prospect for us, and your mission will be to help us deliver this!

The Model Development Experience (MDX) Team’s mission is to empower our customers to build and iterate their models faster, easier and with advanced tooling to provide novel insights and assistance. In addition to these new experiences, we are committed to improving our existing user flows and modularising our technical systems to reduce complex coupling with other teams.

Key Responsibilities

• Help us build the right thing by working with product managers, designers, fellow engineers and (sometimes) customers to understand problems and develop solutions
• Help us build the thing right by writing high-quality, thoughtful, simple, commented, documented, tested, well-structured code aligned to our constants, principles and standards
• Help drive our technical standards, decisions, and strategy
• Continually learn and improve yourself - experiment and play with new technologies through your work and hackathons
• Help reduce friction and eliminate impediments that slow us down
• Help your team and the company evolve our ways of working as we grow into new scales of operation.
• Coordinate with other engineering teams to manage cross team dependencies and cooperate on Engineering-wide initiatives.
• Help support our product in production by joining an on-call rota

Required Experience and Skills

• Experience using Kotlin / JVM technologies with Spring & Hibernate - if you are not familiar in Kotlin yet we will help you in up-skilling. If you were coding in Python, Node or .NET we are still interested in a conversation!
• Understanding of Version Control Systems (VCS) and the principles behind them
• Demonstrably good working knowledge of fundamental computer science and software engineering principles (algorithms, data structures, complexity, design patterns, architecture)
• Have experience of a complete product development lifecycle (conception through to delivery)
• Basic knowledge of Python and/or Typescript is a plus but is not required

Interview Process

Initial meeting with our Talent team to kick things off, then:

• 1/ Interview with you future Engineering Manager
• 2/ Skills Interview - refactor and architectural design exercises followed by Technical Interview
• 3/ Values Interview

We aim to finish the process within 2-3 weeks. Then, we offer!

Work mode: Warsaw hybrid, 1- 2 days per week in the office at Czackiego 15/17.
