About the Role
We are seeking a Senior Software Engineer to join as a founding member of our new AI team. You will help build a safe, scalable, and lightweight AI capability from the ground up, developing central developer tools and production gates, and working with business teams to co-build live features.
Responsibilities
- Embed temporarily within cross-functional business teams to co-build high-impact AI features directly inside their domain codebases and smooth out day-to-day bottlenecks.
- Design and build internal developer tools, standard templates, and pipeline gates in Python to simplify how teams across Octopus safely integrate AI into their software.
- Establish clear guardrails, security standards, and production pathways to turn quick AI prototypes into secure, scalable, and well-architected systems.
- Engage directly with both technical and non-technical stakeholders to help map out fuzzy operational problems, understand pain points, and design practical AI-augmented workflows.
- Collaborate closely with the Data team to ensure data flows securely and effectively into front-facing AI tools and applications.
- Provide hands-on pairing, mentorship, and technical guidance to local teams during embedded rotations.
- Gather insights from on-the-ground embedded deployments to feed real-world requirements back into central prototyping tools, patterns, and frameworks.
Requirements
- Strong technical background in backend engineering with deep fluency in Python/Django.
- Solid understanding of system design.
- Genuine interest in Developer Experience (DX) and system reliability.
- Hands-on familiarity and curiosity with modern AI toolchains, LLM integrations, retrieval patterns, and rapid prototyping frameworks.
- Ability to audit AI-generated code.
- Strong stakeholder management and communication skills.
- Proven ability to collaborate effectively across deeply technical tech teams and non-technical business partners.
- Pragmatic builder mindset that prioritizes shipping fast, practical value.
- Excellent collaborative and coaching skills, with demonstrated experience in pair programming, mentoring, or elevating team capability.
- High accountability and a low-ego approach to handing off projects.
- Comfort working in a fast-paced, high-autonomy environment.
- Ability to navigate context-switching between projects and help shape workflows from the ground up.
