Backend Developer

Focused Remote Backend Developer Job Description

We are seeking a highly skilled and adaptable Remote Backend Developer to join our small core team. The ideal candidate will be pivotal in evolving our backend architecture, focusing on building our new primary API using Java or Kotlin and developing specialised, high-performance micro-services using Node or handling data analysis tasks with Python.

We welcome exposure to high performance languages such as Rust and GoLang that work well within the AWS eco-system.

Key Responsibilities

  • Design, implement, and maintain the new core API service, primarily using Java or Kotlin.
  • Develop specialised micro-services; using GoLang or Rust for performance-critical services and Python for data analysis, LLM training (RAG/MCP) and occasional backend scripting.
  • Develop, secure and manage RESTful/GraphQL APIs for our ecosystem.
  • Manage deployment pipelines, including containerization and orchestration using Docker/Kubernetes/ECS.
  • Optimize database schemas and queries for both relational (PostgreSQL) and NoSQL (MongoDB) data stores.
  • Manage and administer our AWS infrastructure, with a focus on IAM security and role management.
  • Some knowledge of PHP Laravel is only required to understand the business logic in the legacy API platform..
  • Collaborate closely with team members on architectural design and code reviews.

Technical Expertise Required

Candidates must demonstrate deep commercial expertise in the following key areas:

  • Primary API Platform: Proven experience with either Java or Kotlin.
  • Micro-service Tooling (1+ Required): Experience building production services with GoLang (preferred for performance) or advanced experience with Python for data-intensive backend tasks.
  • Data Analysis: Proficiency with Python and standard data analysis libraries such as Pandas, SciPy, and NumPy.
  • API Development: Strong commercial track record in designing, implementing, and securing high-volume APIs.
  • Database Mastery: Expert working knowledge of PostgreSQL and MongoDB. Any experience with MySQL, SQL Server or Oracle is beneficial.
  • Cloud Operations (AWS): Hands-on experience administering and configuring AWS environments. Deep understanding and experience with IAM role management is critical.
  • Deployment & DevOps: Practical experience with Docker and orchestrating deployments using Kubernetes and/or AWS ECS.

Why This Role is Unique

This role offers a unique opportunity to work with a polyglot backend, applying the right tool for the job, e.g. Java/Kotlin for stability and robustness, GoLang for speed and Python for data science.
