Full Stack Engineer

London, England, United Kingdom

Opportunity

Brunswick is recruiting for a Full Stack Engineer to join our pioneering AI Lab.

Brunswick’s AI Lab serves as the firm’s central hub for AI innovation. The Lab researches, builds and maintains cutting-edge AI solutions, while partnering with client teams to provide advanced technical expertise on complex mandates.

As AI adoption accelerates across the firm, the Lab plays a critical role in ensuring Brunswick remains at the forefront of AI-enabled advisory work and equipping our teams with the tools, skills and confidence to deliver differentiated value to clients.

This role focuses on the structured design and disciplined delivery of production-grade internal applications. While hands-on engineering is central, equal importance is placed on stakeholder engagement, strong UX/CX thinking, clear problem definition, robust solution design and adherence to sound SDLC practices. 

The successful candidate will work closely with stakeholders across the firm to translate business needs into scalable, well-architected AI-enabled solutions.  

About the Role 

Your day-to-day responsibilities will include:

Design: 

  • Lead discovery sessions to clarify objectives, constraints and outcomes before development begins. 
  • Translate ambiguous business requirements into clear technical approaches, designs, implementation approaches and delivery estimates.  
  • Validate scope and assumptions with stakeholders to minimise rework. 
  • Design intuitive, user-centred interfaces that drive adoption and engagement. 

Stakeholder Engagement 

  • Engage confidently with Partners, Directors and end users to refine requirements. 
  • Communicate trade-offs, timelines and technical constraints clearly. 
  • Provide structured updates throughout delivery to maintain alignment. 

Engineering and Delivery: 

  • Apply disciplined SDLC practices including version control, testing, documentation and CI/CD and SDLC process optimisation. 
  • Collaborate with Security and ICT teams to ensure compliance and resilience. 
  • Identify technical and operational risks early and propose mitigations. 
  • Build, support, and iterate existing AI applications. 
  • Leverage emerging tools to help accelerate delivery of new business capabilities.

What We're Looking For

The successful candidate will combine strong stakeholder management skills, user-centred design thinking, full-stack engineering capability, and experience delivering end-to-end systems. Standout candidates demonstrate:

  • Proven ability to apply UX/CX principles in digital product development.
  • Ability to translate business requirements into structured technical designs.
  • Comfort working directly with stakeholders to shape solutions.
  • Experience working within structured SDLC practices that deliver business critical systems (testing frameworks, CI/CD, version control, documentation).
  • Strong Python development experience, with a track record of writing clean, production-quality .
  • Strong front-end development skills (React, JavaScript, HTML, ).
  • Hands-on experience building solutions that integrate with AI.
  • Experience designing APIs and integrating with enterprise systems.
  • Experience building cloud-native applications (Microsoft Azure experience desirable).
  • Knowledge of secure development practices and awareness of modern security considerations (Desirable).
  • Strong understanding of the generative AI landscape and how to apply it practically.
  • Experience working with tools such as Claude Code or OpenAI Codex (desirable).
  • Experience in professional services environments (beneficial).
  • Familiarity with BMAD or similar delivery methodologies (desirable).
