The backend Tech Lead day to day involves:

  • Write and review some Java or Kotlin code helping other teammates
  • Tackling legacy parts and handling tech debt backlog
  • Help teams with mid and long term technical plans
  • Promote best practices across teams (DDD, event driven architectures, testing, monitoring…)
  • Mentoring other teammates to get the better of them

The challenge

As a Backend Tech Lead, you will contribute to construct a team culture, with the rest of the technical leads, based on a continuous improvement attitude, trust and a self-empowerment philosophy. So, among others, you will drive teammates to have a complete ownership of the services embracing DevOps philosophy.

One of the current challenges is working completely remote since COVID-19 and improving the communications and documentation inside the company about technical achievements and possible issues.
Some of the interesting things we are currently doing at technical level, include finding new ways to handle complexity, improve resiliency and escalate the team.

It's difficult to explain our stack but the most important parts are:

  • Kotlin & Java
  • Spring, Axon Framework & Ktor
  • RabbitMQ
  • MySql, DynamoDB, Redis & Memcached
  • Docker
  • ElasticSearch & Solr
  • Kibana, Grafana, InfluxDB & Prometheus
  • AWS: S3, ECS, CloudWatch, RDS, CloudFormation, Lambdas & more
