The UK's specialist lending market is underserved by technology, with legacy systems that can't handle the nuance of complex income, niche products, or the broker workflows that specialist lenders rely on.
We're building modern, cloud-native lending technology, purpose-built for specialist lenders, that helps them process more applications in less time, reach decisions faster, and deliver better experiences for brokers and borrowers.
We're pioneering the use of AI in mortgage origination, building it into the platform from the ground up rather than bolting it legacy architecture.. We work with regulated lenders across the UK, have a 100% delivery track record, and are building a high-performance team where everyone has real ownership and direct impact.
This is not a traditional support role, and you do not need any previous customer support or technology experience to apply.
This role is ideal for a recent graduate or someone early in their career who wants to get into tech
You will help lenders, brokers, and internal teams get the best out of Mast. You will answer questions, investigate issues, improve support processes, create documentation, spot recurring product friction, and turn customer conversations into ideas that shape the platform.
You'll report to the Head of Product and work closely with Product, Engineering, Client Success, and Implementation. Over time, this role has the potential to grow into leading Mast's customer support function as the company scales.
Triage, investigate, and manage support requests from start to finish, escalating to Product or Engineering where needed while keeping people informed.
You will build deep knowledge of Mast's platform, including mortgage journeys, forms, policy prompts, automations, integrations, product configuration, and broker/lender workflows.
Help design how support works at Mast: ticketing workflows, escalation routes, response templates, internal runbooks, help centre content, and reporting dashboards.
You will look for repetitive questions and manual processes, then automate them through better tooling, documentation, AI-assisted workflows, or process changes.
Because this role reports into Product, you will do more than answer questions.
You will identify patterns in customer feedback, recurring pain points, confusing workflows, and missing features, then translate those into product ideas, bug reports, and roadmap input.
Write clear, practical help articles, FAQs, release notes, troubleshooting guides, material, and internal playbooks.
You will help keep everything up to date as the platform evolves.
Use AI tools to draft documentation, summarise issues, identify patterns, write clearer responses, and speed up repetitive work.
You don't need to be an AI expert. We are looking for someone curious, experimental, and willing to learn.
We are not looking for years of experience. We are looking for potential.
You may be a recent graduate or early in your career. You do not need previous customer support, fintech, mortgage, or software experience.
The most important things are that you:
Have a great attitude and want to learn quickly
Are reliable, thoughtful, and willing to take ownership
Can work independently, spot what needs doing, and make progress without needing detailed instructions every time
Communicate clearly and calmly in writing
Are organised and detail-oriented, especially when managing several issues or follow-ups at
Are comfortable asking questions when something is unclear
Enjoy solving problems and making things easier for others
Are curious about technology, software, and AI
Are comfortable working remotely and managing your own time
Naturally ask, “How can this be easier next time?”
Familiarity with tools like Notion, Slack, Linear, Jira, Zendesk, Intercom, HubSpot, Loom, Metabase, or AI tools like ChatGPT and Claude
Experience from university projects, internships, part-time work, customer-facing roles, or startup environments
Interest in product management, customer success, operations, automation, or fintech
Experience writing clear documentation, guides, or process notes
First 3 months: Strong understanding of Mast's platform and customer workflows. Ownership of incoming support requests. Clearer processes for tracking and resolving issues.
6 to 12 months: Reduced repeat questions through better documentation and automation. A reliable feedback loop into Product. Clear visibility into where customers struggle and where the product can improve.
Longer term: You help define what excellent customer support looks like at Mast, and may grow into leading the support function.
