About ARIA
ARIA is a new kind of R&D funding agency. We fund scientists and engineers to pursue research at the edge of the possible. From climate change to AI, society faces enormous challenges and opportunities that can be uniquely addressed by science and technology. ARIA was created to activate the UK’s world-class R&D in new ways, so we can meet these head on.
We are growing our team to develop bold new approaches that can scale – from programmes to systems, processes and everything in between. If that sounds fun, come and build ARIA with us.
Learn more about how we work here.

Role Summary
To accelerate ARIA’s transition toward frontier operations by replacing or restructuring manual, bottlenecked processes with AI-driven solutions (i.e., workflow automation & AI integration).
This role will act as the technical engine for ARIA’s workflow transformations, turning high-level blueprints into functional digital tools that increase the agency's operational bandwidth. This role will focus on building and integrating the bespoke software and automations that enable the organisation to coordinate, operate, and scale multiple breakthrough research projects.

Our Tech Stack includes the following:
  • Python 3
  • CI/CD
  • Docker
  • TailwindCSS
  • Jinja2
  • HTMX / HTML
  • Github

What you’ll do


  • Interact with Project Managers and Data Engineers to reach the best possible technical design
  • Develop and implement technical workflow solutions including integrations between systems, AI-embedded workflows, and custom interface builds
  • Build the middleware and API connections required to ensure various SaaS systems and internal data sources communicate and integrate seamlessly
  • Produce clear technical documentation and playbooks to transition successful pilots into stable, Business-as-Usual (BAU) operations
  • Prototype and build lightweight frontends using TailwindCSS, Jinja2, and HTMX to turn high-level operational blueprints into functional digital tools.
  • Collaborate closely with internal teams to shadow manual processes, diagnose operational bottlenecks, and translate non-technical feedback into concrete automation requirements.
  • Maintain and optimize deployment pipelines using Docker and CI/CD tools to ensure rapid, reliable, and secure software delivery.
  • Monitor, iterate, and troubleshoot newly launched pilot tools, utilizing user feedback and performance data to make swift engineering adjustments.
  • Participate in code reviews and security checks, ensuring that any tool built adheres to essential data protection and identity access controls.
  • Involvement in and contribution towards pilot launches of 3–5 high-impact, AI-augmented workflows.
  • Clear documentation of design choices, implementations and user-guides for any released tooling / libraries

Who you are


Essential
  • Technical builder with a foundation in Python development for backends and command line tools
  • Experience in designing internal APIs and consuming APIs from 3rd party platforms
  • Understand databases and ORMs to be able to create clean schemas, and query data
  • Familiarity with Git for source control, within a collaborative environment
  • Requirement gathering from non-technical stakeholders and translating into technical requirements
Desireable
  • Possess a practical understanding of automation and Large Language Models (LLMs) and has experience in prompt engineering and agent-based architectures, but may also be skeptical and guarded with respect to AI and how it should be applied.
  • Hands-on, execution-oriented engineer who can adapt quickly based on pilot performance data and user feedback.
  • Understands the importance of technical security controls, such as IAM and encryption, especially when handling sensitive data or PII

Benefits


  • 27 days annual leave provision
  • Hybrid working arrangements; 60% in office / 40% at home

  • A free and confidential 24/7 employee assistance programme
  • Life Assurance
