Company Description
Job Description
We’re looking for a senior full-stack engineer with a strong interest in building AI-first products who enjoys owning problems end-to-end – from vague client needs and early hypotheses to production-grade systems that actually get used.
What you’ll do
You’ll join The Tech Collective (our Data & AI hub, specifically), where we help organisations design, build, and operationalise data- and AI-driven solutions.
This role is tailor-made for a systems thinker and builder – someone who has shipped real products, taken responsibility for technical direction, and is motivated by creating pragmatic solutions that combine data, software, and AI.
You’ll work closely with experienced AI specialists who bring deep model and ML expertise, while you focus on building robust products and software around those capabilities.
Your responsibilities will include:
- End-to-end solution ownership: designing and implementing full-stack applications from early concepts and prototypes to scalable, production-grade systems, including architecture decisions across frontend, backend, data, and cloud
- Modern full-stack development: building high-quality frontend and backend services, applying sound software engineering principles, and using AI-assisted development tools thoughtfully and critically
- AI-enabled product building: collaborating with AI specialists to integrate LLMs, retrieval pipelines, and agentic patterns into real products, and translating AI potential into solutions that make sense for organisations
- Data and systems thinking: designing data models, reasoning about distributed systems and trade-offs, and implementing event-driven or real-time features where they add value
- Observability and evaluation: experience setting up the right observability and eval tooling to establish traceability and iteratively improve on products
- Cloud, delivery, and collaboration: deploying and operating solutions in cloud environments, balancing speed, robustness, and security, and working closely with clients and stakeholders to create tangible business impact
What you’ll bring
We’re looking for someone with an AI builder mentality and 5+ years of hands-on full-stack experience, who is comfortable owning applications end to end – from frontend and backend to data and deployment.
You don’t need to tick every box, but you should recognise yourself in most of the following:
- Strong full-stack foundation: solid skills in TypeScript and/or Python, with experience building and shipping production systems
- Mentoring experience: helping other developers through technical sparring and code reviews
- Outward curiosity: actively seeking to understand client problems in detail and working in close collaboration with them to solve them
- Ownership and leadership: a track record of building substantial solutions from scratch (e.g., startup, scale-up, or personal ventures), taking responsibility for outcomes, and leading technical direction without relying on formal authority
- System-level thinking: the ability to reason about architecture, data flows, trade-offs, and failure modes across the stack, and to make pragmatic decisions in ambiguous contexts
- Critical technical judgement: a keen eye for identifying weaknesses in existing architectures and tech stacks, and knowing where and how to improve them
- Communication and collaboration: the ability to explain complex technical concepts clearly to non-technical stakeholders, work across disciplines, and learn from – and share knowledge with – others in the team and across Implement
- Tool agnostic: capable of choosing the right tool for the job
What we offer
We offer a role with technical ownership and influence, working in a 20-person team that feels much closer to a nerdy startup than a large corporation – while being firmly backed by Implement Consulting Group.
You’ll gain exposure to a wide range of data- and AI-driven problems across industries, all within a culture built on trust, curiosity, humility, resilience, and impact. You’ll also have great freedom to shape your own role, deepen your expertise, and grow in exactly the direction that motivates you.
