Backend Engineer (Java/Springboot)

About the role:

As a Backend Engineer, you independently plan, develop, implement and test software programs that are easy to maintain, modular, well documented, and resource efficient

As a Backend Engineer, you will:

• Be a core member of the Backend Engineering team and maintain our best-in-class product, a Java based micro-services architecture that is fully cloud hosted on AWS.


• Work alongside other engineers on the team to maintain technology standards and participate actively in code reviews, assisting with the application of standards around i.e. software quality, security, and correctness.


• Perform operational procedures, including ongoing maintenance, on runtime systems, both manual and automated, in accordance with company standards.


• Participate in the broader process of defining system architecture - both in terms of software and systems.


• Provide recommendations for continuous improvement to the product and delivery process.

Our Technical Environment  

• Our next generation payments platform has been developed using Java – specifically leveraging the Spring Boot framework


• Our infrastructure is hosted on AWS; using a mixture of containerization (Fargate) and vanilla EC2


• We use Amazon MQ (RabbitMQ) as message broker to enable asynchronous communication between services


• Our systems are secure and highly available – we have implemented passive and active monitoring and incident escalation using a combination of Datadog, CloudWatch Logs and Metrics, Postman, and Pagerduty


• We utilise GraphQL (leveraging Apollo and Hasura) to open up our rich data model to internal and external stakeholders


• We develop frontend systems using the Vue, Angular, and Ionic frameworks


• We aggregate and analyze logs from all of our systems via the ELK stack


• Our operating system of choice is CentOS and our DevSecOps team is fanatical about security, monitoring, and patch management


• Our infrastructure is immutable and managed using IaC principles via Terraform


• We leverage build automation (specifically CircleCI), and we’re working toward continuous deployment across all environments


• We take advantage of AWS services to meet our various technology requirements:


• PostgreSQL databases run on Aurora Serverless or Aurora clusters managed via RDS


• Redis clusters are managed via ElastiCache


• KMS provides managed security services


• AWS Lambda and API Gateway support our serverless infrastructure; DynamoDB is also an important part of our stack


• We utilise highly durable messaging technologies such as SQS, Kinesis, Amazon MQ and AWS EventBridge

Requirements

• 5+ years’ software development or programming experience, with an in-depth understanding of distributed systems


• Good working experience with Java(8 or later), with experince in Spring Boot Framework and SQL


• Solid grasp of computer science fundamentals, specifically data structures and algorithms.


• Working knowledge of a modern software development lifecycle management methodology, such as SCRUM
