Backend Engineer (Contract)

About the Role
You are a systems thinker with deep experience in backend engineering and distributed
data infrastructure. You thrive in high-stakes environments, know how to ship reliable
code fast, and are pragmatic about trade-o=s. You understand the unique constraints of
experimental, edge-deployable systems, especially in air-gapped environments where
resilience and autonomy matter most.
This role focuses on building and adapting backend services to support experimental AI
systems deployed in sensitive Defence contexts. You will help create and manage
robust, portable pipelines for data ingestion, orchestration, model interaction, and
querying - all within a classified, compute-constrained environment. While our SaaS
platform handles production-scale workflows, this project demands thoughtful
downscaling and adaptation, not replication. You will work closely with a cross functional team of frontend engineers, data scientists, platform engineers, and external
partners.

What You'll Do
* Architect and implement backend services that support secure, air-gapped AI
deployments, with a focus on NLP-based tooling
* Develop pipelines for transcription ingestion and real-time analytical insight
generation
* Support graph and RAG-based inference layers using data from structured and
unstructured sources
* Build and expose APIs for frontend consumption, enabling natural-language
querying, dynamic visualisation, and reporting
* Ensure system portability via containerisation
* Collaborate closely with data scientists to integrate self-hosted LLMs and
analysis models into the backend infrastructure
* Work with platform engineers to tune deployments for hardware-limited
environments
What You Bring
* Strong experience building secure, scalable backend systems in Python and/or
Go
* Deep understanding of containerised services, particularly in Kubernetes
environments
* Practical knowledge of orchestration tools (e.g., Argo), message buses (Kafka),
and databases (especially Postgres), or equivalent technologies
* Experience working in air-gapped or secure environments, or at minimum, a
clear grasp of the constraints and workarounds involved
* Comfort designing APIs for real-time and batch AI/ML pipelines
