Jobbeschreibung

Klar is working hard to bring digital banking to those who need it in Mexico. What is so special about digital banking? Nearly half of people in Mexico have no bank account at all. This puts their savings at risk of theft, destruction during floods or fires, and can make the very act of bringing money for large purchases a danger. Traditional banks have overhead costs per customer that make it unprofitable for them to serve people with smaller deposits or who live in remote areas. By bringing down the cost of banking, Klar is working towards making it possible for the people who need it most to get access to a line of credit to carry them through a rough week or help them grow their own small business.

We need Senior Backend Engineers to build flexible and reliable software systems that scale and bring the costs of digital banking down.

What you’ll do :

1. Write correct, efficient, clean, robust, and maintainable code. (Mostly in Java 11)
2. Write unit, integration, and end-to-end tests to prevent current errors or future regressions.
3. Participate in code review to learn from others and to teach them as well.
4. Prototype new technologies and libraries that could save time and effort.
5. Mentor more junior engineers.
6. Write clear and concise documentation for users of your systems.
7. Identify common problems between multiple systems and develop common solutions via libraries.
8. Create designs for new systems and features of moderate complexity.
9. Make time estimates to implement designs which can aid in future planning.

What you’ll bring :

1. At least 6 years experience with several of the following development technologies: Java 11, SpringBoot, PostgreSQL or other relational databases, Apache Kafka, Redis, Protocol Buffers.
2. At least 3 years experience with microservice architectures, synchronous REST communication over HTTP, and asynchronous communication over Apache Kafka.
3. Knowledge of algorithms and data structure for distributing load like sharding, optimistic locking, database transactions, leadership election, and more.
4. At least 3 years experience with the following infrastructure technologies: AWS, Jenkins, Kubernetes, Istio, Terraform, Terragrunt, Helm.
5. At least 3 years experience with logging and metrics technologies: DropWizard, Prometheus, Grafana, Kibana.
6. Strong written and verbal English communication skills and comfortable taking into account peer review to improve designs and correct mistakes before they are made.

How we work :

1. Measure Twice and Cut Once: Teams produce peer-reviewed designs whose structure resembles a scientific publication. We encourage all departments to participate in peer review to catch mistakes early.
2. Respond to Critique: We use tools and technologies that speed up how fast a design can be updated to take into account identified flaws and then be improved.
3. Independent Teams: Teams are free to choose how they accomplish their goals. Results matter far more than adherence to specific methodologies.
4. Lead from the Front: There are no pure managers and everyone gets their hands dirty from Junior Engineers to the CTO.
5. Quarterly OKRs: For larger work items that require coordination between multiple teams, we use OKRs representing 1 to 3 months of work which are used for planning.
6. Clear Performance Evaluation: Performance evaluations begin with employees listing their accomplishments and demonstrating expertise in clear job responsibilities. Performance is evaluated with care to assure fairness and openness in scoring and in pay.

What we offer :

1. Competitive salary based on performance and experience.
2. Stock options.
3. 26 days of paid vacation days per year.
4. 1500 EUR annual education/training budget.
5. Flexible working hours and ability to work remotely.
6. A modern and centrally located office.
7. Strong growth prospects and shareholder confidence with $20M in recent investments.
