THE ROLE We’re looking for a Senior automation engineer to join our Automation & AI Enablement team. Reporting to an Engineering manager, you’ll work closely with colleagues across engineering, product, operations and our customer-facing teams to identify complex operational problems and create simpler, faster and more scalable ways of working. The team helps Seccl make better use of automation and AI as we continue to grow. You’ll get under the skin of ambiguous processes, design improved workflows and build practical solutions using the right tool for the problem – whether that’s TypeScript, Python, an agentic system or a low-code platform such as Zapier or Microsoft Power Platform. You’ll take ownership from initial discovery through to delivery and operation, balancing speed, quality and long-term maintainability. ON A TYPICAL DAY YOU WILL BE… - Working with engineering, product, operations and customer-facing teams to uncover inefficient, manual or unclear processes - Turning ambiguous business problems into well-designed, scalable automated workflows - Choosing the right tool for each problem, from TypeScript or Python to LLMs, agentic systems and low-code platforms - Designing, building, testing and operating reliable automation and AI-enabled services - Applying appropriate quality gates, guardrails and human oversight to AI-driven workflows - Owning your solutions throughout their lifecycle, including documentation, observability, support and continuous improvement - Evaluating emerging LLM models, agentic tools and automation approaches based on their practical benefits and trade-offs - Sharing your knowledge and helping other engineers and teams adopt effective automation practices THIS ROLE’S FOR YOU IF... - You have strong commercial experience with TypeScript or Python and are willing to learn whichever language is less familiar to you – TypeScript experience is slightly preferred - You have experience writing or using agentic harnesses for software development and understand how to assess different orchestration approaches - You understand the current frontier LLM landscape, its applications in software engineering and challenges such as hallucination, prompt injection, privacy, cost and latency - You’re comfortable choosing the right tool for the job, including low-code platforms such as Zapier or Microsoft Power Platform when custom code isn’t the best answer - You have an enablement mindset and naturally seek out ambiguity, inefficient processes and opportunities to design better ways of working - You’re a hands-on builder who wants to understand a problem deeply, build the solution and remain accountable for running and improving it - You understand how to make automation and AI-enabled systems reliable through testing, observability, validation, guardrails and human-in-the-loop review - You have experience working with cloud-based systems – AWS, serverless technologies, regulated industries or financial services experience is desirable THIS ROLE ISN’T FOR YOU IF... - You rely on a lot of top-down direction. Here, you’ll have a lot of freedom and ownership of your role, and you’ll be expected to shape your own progression - You’re not comfortable working in a fast-paced environment.…
