Summary Generated by Built In

Smappee (Smart Appliance for Energy Efficiency) helps businesses and individuals take control of their energy consumption. Through innovative energy management and EV charging solutions, we make energy efficiency accessible, helping reduce costs and contributing to a more sustainable future.   

What does it mean to work at Smappee?   

At Smappee, we take ownership, collaborate openly, and communicate transparently. We stand behind our commitments and aren’t afraid to experiment, challenge ideas, and grow through change.   

Position

As a Backend Developer, you help build the backbone of Smappee’s energy management platform. You develop and own a part of our platform that connects our energy solutions with households, businesses, installers and partners to manage energy smarter. Whether you work closer to our devices or on the services and APIs powering our platform, your work has a direct impact on how Smappee measures, manages and optimises energy. As our platform evolves, so can your focus, giving you the opportunity to grow your expertise while helping shape the future of our technology.

Responsibilities:
  • Design, build and maintain Java backend services in our cloud platform and you own a domain within it rather than passing through it
  • Work on the path from device to platform: data coming in, configuration going out and the model of an installation staying correct as it changes
  • Develop the APIs that our UI and our partners consume
  • Build and maintain the integrations the platform depends on, towards devices and towards the systems around us
  • Act as third line support for your domain: you pick up escalated tickets, investigate incidents and turn the outcome into follow up work in the product
  • Work directly with product management, firmware engineers, app and frontend developers and software testers, from the first design discussion rather than from a finished specification

Requirements
  • You have a bachelor's or master's degree in computer science, or equivalent experience
  • You have least five years of experience as a backend software engineer
  • You are strong in Java and comfortable with relational databases and SQL (MySQL, Postgres)
  • You have built event driven and message based integrations (Kafka, MQTT or comparable) and REST APIs that you both consume and expose
  • You are at ease in a cloud environment (AWS) and working in a large modular codebase
  • You can hold a full system in your head: hardware devices on one side, customers on the other and you reason clearly about what happens when one part of it goes offline
  • You learn quickly and adapt. New domains, unfamiliar code and shifting priorities are part of the job and you help the people around you keep up as well
  • You take ownership. An escalated issue in your domain stays yours until it is solved

Benefits

At Smappee we believe in a modern, dynamic, flexible work environment and culture where you can be yourself and truly inspire people to contribute to a better planet. What can you expect exactly?  

  • An inspiring office environment at cleantech hub Snowball: a place where companies with a heart for sustainable innovation can get inspired and grow.  
  • Personal growth with multiple career and personal development opportunities in an organization that is constantly evolving.  
  • A chance to participate in team activities, companywide events and monthly drinks with your colleagues at the HQ.  
  • Remuneration according to experience, completed with extra-legal benefits such as an electric company car and charging card or mobility budget, meal vouchers, eco vouchers, health insurance, group insurance and holidays supplemented with ADV days.  
  • A flex benefits plan with optional benefits such as bicylce leasing, multimedia, home office supplies, additional holidays, refund of individual pension savings and warrants.  
  • A job where you can truly contribute to a better planet.  

Skills Required

  • Bachelor’s or master’s degree in computer science, or equivalent experience
  • At least five years of experience as a backend software engineer
  • Strong Java skills
  • Experience with relational databases and SQL, including MySQL or PostgreSQL
  • Experience building event-driven and message-based integrations using Kafka, MQTT, or comparable technologies
  • Experience building and consuming REST APIs
  • Comfort working in AWS cloud environments
  • Experience working in a large modular codebase
  • Ability to reason across hardware devices, platform systems, and customer-facing services
  • Ability to learn quickly, adapt to new domains, and support colleagues
  • Strong ownership of escalated issues through resolution
