Cambridge University Press & Assessment
Shaftesbury Road, Cambridge, UK
Job Title: Lead Software Architect
Salary: £68,600 to £91,700
Location: Cambridge, UK – Hybrid
Contract: Permanent
Hours: Full time, 35 Hours Per Week
Are you enthusiastic about shaping technology that delivers impact at scale?
As we continue to evolve our digital platforms to support learners, lecturers and researchers around the world, we are looking to appoint an experienced and motivated Lead Software Architect to join our Academic Technology group here at Cambridge University Press & Assessment, a world‑leading academic publisher and assessment organisation and a proud part of the University of Cambridge.
This is a fantastic opportunity to play a meaningful role in shaping the technical foundations of globally used digital products, ensuring they remain scalable, secure and fit for the future.
About the role
As Lead Software Architect, you will be accountable for owning the software architecture and engineering delivery across a product or platform vertical within our Academic Technology group.
Working at the intersection of solution architecture, product and engineering, you will translate solution designs and product priorities into well‑architected, shippable software, ensuring that technical direction is sound and delivery is sustained from planning through to production and live operation.
You will provide technical leadership across the full engineering lifecycle, including backend and frontend architecture, infrastructure, CI/CD pipelines and operational readiness. While this is not primarily a hands‑on coding role, it requires a strong engineering background and the ability to review code, challenge design decisions, unblock engineers and engage directly where it adds value.
A core aspect of the role is leading the adoption of AI‑enhanced engineering practices. You will shape how teams use AI‑assisted tooling across planning, development and quality assurance, focusing on responsible, practical use that measurably improves delivery quality, throughput and maintainability.
You will work closely with Solution Architects, Product Owners and UX colleagues to ensure requirements are technically feasible, well specified and correctly decomposed, acting as the key technical bridge between solution intent and engineering execution.
Additional responsibilities and accountabilities:
Owning the software architecture for an assigned product or platform area, ensuring solutions support both current delivery and future scalability.
Driving engineering delivery from planning through to production, translating solution designs into implementable engineering plans with clear scope, dependencies and sequencing.
Providing technical leadership and direction to distributed engineering teams, including Far shore, near shore and contract resources.
Removing technical blockers, making pragmatic trade‑off decisions and keeping delivery on track.
Defining and upholding technical standards, patterns and engineering conventions.
Leading the adoption of AI‑assisted software development practices and tooling across engineering teams.
Owning operational readiness, including infrastructure, CI/CD pipelines, monitoring and developer experience.
Evaluating technology and tooling choices, including build‑vs‑buy decisions, with clear and defensible rationale.
This position has been classified as a hybrid role, requiring the selected candidate to typically spend 40-60% of their time collaborating and connecting face-to-face at their dedicated location. Aside from our hybrid principles, other flexible working requests will be considered from the first day of employment, including other work arrangements should you require adjustments due to a disability or long-term health condition.
About You
As a senior software architecture or engineering leader, you will have a proven record of owning complex platforms or digital products end‑to‑end. You will be confident operating across technical and non‑technical audiences, bringing sound judgement, strong communication skills and a pragmatic approach to decision‑making.
You will have experience translating product and solution designs into engineering delivery, leading distributed teams, and balancing technical quality with delivery pace in complex environments.
If you meet the above minimum requirements, we encourage you to apply.
Your application will be even stronger if you can also demonstrate experience in content platforms, education technology, modern web technology stacks, or introducing new engineering tools and practices.

AI Trainer - Advanced Indonesian Fluency - UK Remote AI Trainer - Advanced Indonesian Fluency About Prolific Prolific is not just another player in the AI space - we are building the biggest pool of quality human data in the world. Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills. The role We are seeking Fluent Indonesian Speakers from Indonesia to act as evaluators. AI models are now learning to communicate with human-like nuance, and we need fluent speakers to ensure these models understand the cultural and emotional depth of the Indonesian language. You will be assessing how well an AI model captures human emotions, intonations, and sentiments in Indonesian. This is a fast-paced project where your ear for detail directly influences how AI understands human feeling. Researchers looking for your skills tend to pay up to $24/hr. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter. What you'll bring Fluency in Indonesian: you must be a fluent Indonesian speaker from Indonesia. Linguistic Nuance: an ability to distinguish subtle shifts in sentiment and vocal delivery. Communication: fluent English skills for instruction following and reporting. Soft Skills: high emotional intelligence; backgrounds in acting, therapy, or linguistics are a plus. Technical Setup: access to a quiet environment and high-quality audio equipment (headphones/speakers). What you'll be doing in the role Audio Localization: reviewing Indonesian audio clips generated by or for AI models. Sentiment Analysis: assessing the model's ability to convey specific emotions, intonations, and feelings. Quality Control: identifying where the AI's "tone" feels unnatural or culturally mismatched. Audio Assessment: listening to AI-generated or processed audio to verify "human-like" quality. Contextual Review: Identifying if the intonation matches the specific Indonesian cultural context of the conversation. Benefits Joining our platform as a Prolific participant will give you the chance to influence the AI models of the future using professional expertise. Once you pass our assessment, you can join Prolific in just 15 minutes, and start enjoying competitive pay rates, flexible hours, and the ability to work from home. We believe that the next leap in AI capabilities won't come solely from scaling existing models, but from integrating diverse human perspectives and behaviours into AI development. By providing this crucial human data infrastructure, Prolific is positioning itself at the forefront of the next wave of AI innovation.
