About Position
We are looking for a Backend Developer to join an experienced team of developers and help design and implement backend services data models and processes. We are searching for an analytical mind capable of crafting abstractions and solutions for problems imposed by business domain and coding those abstractions using our preferred programming languages. Our focus is on OOP in Scala. While we may use some FP concepts and best practices from time to time we are not an FP shop. Our development follows the Domain Driven Design methodology.
Responsibilities
We design and code. We contribute to a process involving several transformation steps starting from an idea (or a business need) crystallizing it into a relevant domain model coding it and finally spinning it up to run our business 24/7.
Delivery cycle usually corresponds to the following 6 phases:
A Business Domain: It is a customers business of interest.
Model of a customer domain: It is constrained and purified view of a business domain in the form of diagrams drawings text descriptions pictures and specifications.
Model codified in a high-level programming language: High level abstractions with Domain Specification Language which compiles into lower-level programming language. This is where our developers learn and exhibit their software desgine and modelling skills.
Model codified in lower-level programming languages: This is a phase where our developers learn and display their coding skills through Scala Java and PostgreSQL.
Java Bytecode: We trust Java compilers so we usually dont interfere with it.
Machine Instructions: Produced at runtime by bytecode interpretation and JIT compilation.
