The posting

Senior Full Stack Engineer (Remote) - Multiple roles

Simple Machines is a leading independent boutique technology firm with a global presence, including teams in London, Sydney, San Francisco, and New Zealand. We specialise in creating technology solutions at the intersection of data, AI, data engineering, and software engineering.

We design and build bespoke data platforms and unique software products, create and deploy intelligent systems, and bring engineering expertise to life by transforming data into actionable insights and tangible outcomes.

We engineer data to life™.

As we scale our EMEA Engineering Operations, this role will partner closely with our UK leadership team and will focus on supporting our UK-based clients. While you’ll enjoy the flexibility of working remotely, you’ll be closely aligned with our UK delivery teams and client stakeholders, ensuring time-zone overlap and easier collaboration.

Each team member has varying degrees of strength in each area, but all work together across the full stack and assist one another to learn and contribute.

Please note: You must be based in Poland with citizenship or full-time working rights to be considered for the opportunity

The Role:

As a Senior / Lead Full Stack Engineer at Simple Machines, you’ll be at the heart of groundbreaking projects, collaborating closely with both our talented internal team and forward-thinking clients. In this hands-on role, you'll drive the development of sophisticated, scalable solutions across the full technology stack—from intuitive frontends and robust backends to powerful data pipelines and resilient infrastructure. If you’re passionate about solving complex problems and pushing the boundaries of what’s possible, this role offers the perfect platform for you to make a real impact.

Key Responsibilities:

  • Responsible for design and technical development of backend services for a highly scalable marketing platform.
  • Responsible for designing the APIs, applications, and infrastructure the team develops, and documenting the technical requirements and design for the client.
  • Responsible for end-to-end delivery and support, including build, automation, deployment, and operations, for everything that is developed.
  • Partner with client stakeholders, and team members, to gather business requirements, collaborate on design decisions, and translate them into technical and design requirements.
  • Operate within an iterative delivery team using Agile delivery tools and practices.
  • Hybrid remote and in-person collaboration with the delivery team and client stakeholders.

Requirements

  • Past project experience with large scale webservices.
  • Cloud infrastructure experience with AWS and/or Google Cloud, Azure, etc.
  • Infrastructure-as-code (IaC) experience, such as with Terraform or Cloud Formation.
  • In-depth experience with unit and integration testing, and test automation generally. Ideally TDD and/or BDD
  • Experience working with SQL databases in the context of implementing data-driven APIs, and designing database schemas and queries to meet business requirements.

Nice to Have

  • A passion and proven background in picking up and adopting new technologies on the fly.
  • Exposure to Scala, or functional programming generally.
  • Exposure with DynamoDB or similar NoSQL databases, such as Cassandra, HBase, BigTable, or Cosmos DB.
  • Exposure with Git workflows, and the ability to tailor the workflow to project needs.
  • Exposure with containerised application deployment using Docker, Amazon ECS, Kubernetes, etc.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
