London - Hybrid – 2 days per week
£70,000–£80,000 - flex to £90,000 for the right person

We’re hiring a Senior Product Engineer to join a small, high-performing UK tech team operating with genuine start-up autonomy inside a mission-driven organisation.

This is not a ticket-driven development role. We’re looking for someone who can take ownership of problems, shape solutions, and deliver end-to-end features without hand-holding.

The Business

A mission-driven organisation delivering large-scale environmental and climate impact projects across multiple regions. Their work combines science, operational expertise, and technology to drive measurable carbon reduction, protect vulnerable ecosystems, and support sustainable economic development within local communities.

The Role

You’ll take responsibility for a core product domain, working across web, API and mobile applications. You’ll collaborate directly with stakeholders across the business and occasionally customers to deeply understand requirements, then design and build the right solution.

You’ll be trusted to:

*

Identify what needs to be built (not just build what’s spec’d)

*

Design and ship end-to-end features

*

Contribute to system architecture and technical direction

*

Operate confidently in a fast-paced, ambiguous environment

*

Communicate clearly with both technical and non-technical colleagues

This role suits someone motivated by autonomy, ownership, and impact.

Tech & Environment

*

Full-stack development (Front End / API / Cloud)

*

Any Object-Oriented programming language considered

*

Web apps, APIs and mobile apps (Android experience a plus)

*

AI-assisted engineering expected (GitHub Copilot in use)

*

VS Code environment

*

Small UK team (7 people) working closely together

*

Overseas engineering team focused primarily on support

You’ll be part of a tech function that operates like a start-up: fast-moving, low-process, high-trust.

What We’re Looking For

*

5+ years’ experience building and scaling full-stack applications

*

Strong product mindset and end-to-end feature ownership experience

*

Confident communicator, comfortable picking up the phone to stakeholders or customers

*

Experience in early-stage or fast-growth environments preferred

*

Comfortable with ambiguity and self-direction

*

Motivated by autonomy rather than structured task lists

*

Strong engineering fundamentals in an OO language

*

Confident using AI tools to enhance productivity (not reliant, but effective)

The Product

You’ll work across multiple product domains including operational management tools, workforce systems, data measurement platforms, compliance tooling and mobile applications, all forming part of a broader, multi-product ecosystem.

Location

Hybrid – minimum 2 days per week in the London office. Core team typically onsite Mondays and Tuesdays, with flexibility where needed.

If you’re a self-directed, product-minded engineer who enjoys ownership and building meaningful systems end-to-end, we’d love to hear from you.

Private salary
RECENTLY POSTED

ROLE SUMMARY

The AI Creative Builder is a hands-on technical role within the AI Capability function, focused on rapidly prototyping internal applications and tools that improve how teams across OSSAI (Omnichannel Services Solutions & AI) and CX & AI operate. This role takes early-stage ideas and internal process challenges and converts them into functional, validated solutions, often within 24 to 48 hours, using modern development tools, AI platforms and automation frameworks.

Rather than broad external-facing development, the focus here is on building internal prototypes that challenge existing ways of working. You will look at how things are done today, identify where AI can replace manual effort, reduce reliance on external agencies or streamline internal workflows, and then build a working prototype to prove the concept. When a prototype proves successful, you will support its transition into a production-grade solution in partnership with the wider engineering team.

As a core part of the AI Capability team, the AI Creative Builder will contribute to reusable patterns, delivery standards and scalable frameworks that enable faster AI adoption within the organisation. The ideal candidate brings strong technical ability, a sharp eye for internal process improvement, genuine curiosity for emerging AI technologies and the confidence to operate at pace across multiple workstreams in a fast-moving delivery environment.

ROLE RESPONSIBILITIES

  • Assess existing internal processes and workflows across OSSAI and CX&AI to identify where AI-enabled prototypes could reduce manual effort, remove dependency on external suppliers or improve efficiency.
  • Rapidly build working prototypes of internal applications and tools using technologies such as React, NextJS, Python and Supabase, moving from concept to functional demo within days.
  • Deliver AI-enabled internal solutions including automations, workflows, dashboards and micro-applications, iterating quickly based on user feedback and validation.
  • Proactively identify opportunities where internal teams are relying on manual processes or external agencies and propose AI-driven alternatives that can be prototyped and tested quickly.
  • Evaluate and integrate emerging AI capabilities, tools and methodologies to continuously improve the speed and quality of internal delivery.
  • Collaborate closely with the wider engineering team and external delivery partners to transition successful internal prototypes into production-grade scalable solutions.
  • Work alongside the AI Capability Lead to ensure alignment with the OSS AI strategy and roadmap.
  • Apply governance, compliance and security best practices throughout the build process, ensuring all work meets Pfizer standards before transitioning to production.
  • Produce clear documentation and support knowledge transfer to enable solutions to be maintained, iterated and scaled by others across the organisation.

BASIC QUALIFICATIONS

  • Demonstrated experience in software development or applied AI, with a strong focus on rapid prototyping and delivering functional internal applications or tools.
  • Proven ability to assess internal processes, identify improvement opportunities and translate them into practical technical solutions with minimal direction.
  • Hands-on experience with modern development frameworks, low-code tools, AI agents or automation platforms.
  • Strong stakeholder engagement and communication skills, with the ability to convey technical concepts to non-technical audiences including senior leadership.
  • Comfort working in fast-paced, iterative delivery cycles across multiple parallel workstreams.
  • Ability to balance rapid delivery with thoughtful governance and responsible AI usage.
  • Experience with NextJS, Supabase, N8N or AI-powered development environments such as Cursor.
  • Familiarity with AI platforms and services including OpenAI, Anthropic or open-source models.
  • A demonstrable portfolio of applications or internal tools built, such as GitHub repositories, livedemos or side projects that evidence practical delivery.
  • Experience building tools or prototypes that improved internal processes or replaced manual workflows.
  • Track record of taking solutions from early-stage prototype through to production at scale.
  • Bachelor’s degree in Business, Engineering, Computer Science, or related field.

Changed this now. I was confusing this with PDE role as I am working on that in parallel. Hope this makes sense now.

data solutions rather than architectures?

Should add Python here as a key tech we use

Have mentioned Python in ‘Minimum Criteria’ section below, but will add here too

this could be added to Essential Criteria ?

stakeholder and project management ?

Have updated #1 in essential criteria below. But I have now used the previous version to create requisition in OBS. Will see if it can be changed.

What is the difference between “minimum” and “essential” criteria. Both imply that they are mandatory and so could be one list?

This is a bit confusing. I used to have just one, but this is the standard format of JD that the Bank wants us to follow. Here is the difference:

Min Criteria:

This must list the minimum technical skills/experience/qualifications required to do the job and should be measurable/scoreable. The screening questions you select must link to these, in order to allow candidates to best demonstrate their suitability for the role.

Essential:

This lists other important technical skills/experience/qualifications, and also more behavioural competencies. These are ones that are better assessed at interview rather than on screening questions on the application form

Ok, I think we could go back and ask HR about this as it does seem confusing and to me doesn’t give a good impression of the Bank to applicants at it looks like 2 lists for the same thing.

I had checked this earlier, but seems they want us to follow this format. When I advertised last time, I just mentioned Minimum Criteria, but they said it has to be split into Minimum and Essential.

Don’t think we need to mention Atlas or Cloudera Manager as we hardly ever use those. Airflow could be useful so would leave that in.
