Big Hand builds software that legal organisations rely on every day. We are looking for a Full-Stack Engineer to help us design and ship our Matter Pricing products after our acquisition of Ayora AI, where a clean, considered user interface meets genuinely intelligent behaviours underneath.

This is a hands-on role for a Full-Stack Software Engineer who wants their work in production rather than as proof of concept. You will build the conventional and agentic AI experiences that showcase the product, contribute to how problems are framed as well as how they are solved, and take real ownership of the quality of what we release.

• Build and ship features end to end, from interface through to backend services and data.

• Design clean, minimal user experiences with close attention to detail, working alongside design and product.

• Explore and apply agentic AI and LLM capabilities where they meaningfully improve the product and work safely and efficiently with agentic engineering systems.

• Contribute to technical discussion and help refine requirements rather than simply consuming them.

• Deliver consistently within a collaborative agile framework, with a track record of predictable, high-quality output.

• Develop well-constructed solutions using the best tools available, avoiding fragile shortcuts taken for short-term speed or to sidestep discussion.

• Apply modern software development lifecycle practices, including code review, testing and continuous delivery.

• Strong Type Script and React skills, with competency in at least one of our core backend languages (Python and/or Go) or a highly transferable equivalent.

• At least three years of commercial work experience.

• An analytical background, evidenced by a STEM degree in a technical subject. Physical sciences or mathematics are preferred.

• Interest and practical experience with agentic AI and LLMs, and with the intersection between conventional UI and agentic processes.

• Experience working safely and efficiently with agentic engineering systems.

• Experience with design and UX, with a keen eye for detail and for minimalist, clean interfaces.

• A solid understanding of modern software development lifecycle practices.

• The ability to navigate typical problems independently, contribute to discussion and help shape technical requirements.

• An insatiable appetite for learning and for acquiring new knowledge, skills and experience.

• Comfort operating independently on both existing and new systems while preserving and improving a consistent project structure.

• A positive force in building the team as we grow and develop into more senior positions.

• A habit of introducing new technology and practices that accelerate the team, for example through lunch and learn sessions.

• Exposure to our Dev Ops stack: AWS, Terraform and Git Lab CI.

• Experience in the legal industry or another regulated environment such as health or financial services.

• Experience working directly with customers.

• 25 days holiday (exc. bank holidays) + 3 Big Hand days off between Christmas & New Year

• Various wellbeing benefits including private medical, vision, online wellbeing programs & webinars, access to online therapy and Employee Resource Groups (ERG)

• Company-wide Wellness day, for our teams all across the globe to switch off and spend the day doing something to nourish their mental health

• Opportunities to give back with company volunteer events and individual…
