We are looking for a Medior Back-End Engineer
Working at El Niño means working on serious tech projects for international clients of different sizes. Whether it is an energy monitoring platform, a recruitment platform or a webshop: we love a good challenge.
Are you a Medior Back-End Engineer with a few years of experience, who likes building APIs, data models and integrations that just work? Do you want to take full ownership of your work and learn from senior colleagues along the way? Then we'd love to meet you!
As a Medior Back-End Engineer, you build the layer that makes our platforms work: APIs, data models, integrations and background processes. You own your features from first estimate to release and work with senior colleagues on systems that thousands of people rely on every day.
- Build and maintain APIs and back-end services, mostly with Laravel or Symfony
- Design data models and write efficient, well-tested queries
- Build integrations with external systems such as ERPs, CRMs and payment providers
- Own your features from first estimate and dev outline to release and support
- Test your own work, including edge cases and performance
- Review code from your squad members and give constructive feedback
- Pick up support requests and troubleshoot them independently
- HBO-level working and thinking ability, preferably supported by a degree in Computer Science or a related field
- About 2-3 years of software engineering experience
- Strong knowledge of PHP and a framework such as Laravel or Symfony
- Good knowledge of SQL and MySQL. Experience with timeseries databases like InfluxDB or TimescaleDB is a plus
- Familiar with queues, asynchronous processing and web-service oriented architectures
- Experience writing automated tests, for example with PHPUnit or Pest
- Able to debug complicated features on your own
- Basic understanding of DevOps: Docker, servers and CI/CD
- Experience working in Agile teams
- Clear communication, both written and in person
- Fluent in English. Dutch is a plus, but not required.
- Salary transparency: €3100 - €4500
- Focus on employee well-being with sports and health initiatives: 24/7 gym at the office, workouts with a trainer
- Company laptop (choose your own) and high-end office setup
- Refresh, recharge and rave budget (while profits are high): 5% of your working hours
- Learning and innovation time budget: 10% of your working hours
- Learning budget: €1500/year
- Access to premium learning resources, trainings and masterclasses on Udemy, Laracast, GrowthTribe, and more.
- Frequent knowledge sharing sessions
- Future personal development meetings
- Friendly and inclusive company culture with team outings, social events, and trips
- Chef-prepared meals twice a week
- Friday afternoon drinks
- Movie nights in our own cinema
- Time and space work flexibility (except during onboarding)
