About the job

Requirements
  • At least 5 years of software engineering experience with meaningful production ownership.
  • Experience building and shipping LLM-powered systems that ran in production.
  • Production-grade Python as a primary language.
  • Real-world experience working with models via APIs, including harnesses, orchestration, structured output, tool use, agents, and retrieval-augmented generation where appropriate.
  • Experience designing evaluation sets, measuring accuracy, recall, and precision for LLM steps, and regression-testing prompts and workflows.
  • Practical experience with safety and guardrails, including personally identifiable information handling, data-boundary discipline, prompt-injection awareness, and human-in-the-loop design.
  • Experience optimizing model selection, caching, batching, token economics, and latency budgets for cost and performance.
  • Deployment and operations experience with continuous integration and continuous delivery, containerization, and monitoring and alerting for AI workloads.
  • Knowledge of data processing fundamentals, including pipelines, transformation, validation, and anomaly handling.
  • Customer- or stakeholder-facing delivery experience in consultancy, forward-deployed engineering, solutions engineering, or embedded or platform roles serving non-engineering users.
Responsibilities
  • Own AI engagement delivery end to end: scope with the department, design and build the solution, deploy it, and agree on handover and ownership, from prototype through stable production.
  • Engineer AI solutions using pipelines, LLM API integration, evaluations, guardrails, monitoring, and cost and accuracy optimization; determine when steps should be deterministic and when an LLM is appropriate.
  • Rebuild shared, team-load-bearing tools as owned business systems under a full software development lifecycle when the value justifies it.
  • Deploy ML-built components into production, including serving and integrating them with the Moneybox platform, in partnership with Decisioning, Data Science, and engineering teams.
  • Turn engagement learnings into shared tooling, templates, playbooks, and self-serve workflows on the AI Platforms stack.
  • Build platform components including guardrails, sandboxing, workflows, and gateways.
  • Work alongside embedded specialists during the team's ramp-up and internalize their output so the capability remains with Moneybox.
  • Select feasible initial departmental engagements and deliver measurable business value within the first three months.
  • Deploy at least one ML-built capability to production with appropriate evaluations, monitoring, and cost controls within the first three months.
Desired Qualifications
  • Experience with Azure and/or .NET; existing expertise is a bonus, while willingness to integrate with both is required.
  • Experience with agent hosting and sandboxing platforms, LLM or MCP gateways, or agentic workflow orchestration tooling.
  • Experience in financial services or another regulated environment.
  • Experience deploying models built by a data science team into customer-facing production systems.

Simplify's Take

What believers are saying

  • Moneybox hit £115 million revenue and third straight profitable year in 2025.
  • April 2026 AUA topped £22 billion after 100,000 net new Q1 customers.
  • June 2026 pension drawdown and Aurora advice widen cross-sell across retirement assets.

What critics are saying

  • Trading 212 and Plum compress Moneybox cash-ISA economics in 2026.
  • PISCES secondary pricing lacks IPO discipline, risking valuation whiplash before a 2027 listing.
  • Revenue still depends on regulated savings wrappers; FCA rule changes could crush margins.

What makes Moneybox unique

  • Moneybox pioneered UK fintech liquidity via 2026 PISCES employee share sale.
  • It bundles Cash ISAs, Stocks and Shares ISAs, SIPPs, and pensions.
  • Moneybox’s 1.9 million customers and £22 billion AUA create powerful brand trust.

Moneybox launches three new ready-made funds and cuts its fees.

Moneybox launches three new ready-made funds and cuts its fees. Updated: 03:11 EDT, 9 October 2026 Products featured in this article are independently selected by This is Money's specialist journalists. If you open an account using links which have an asterisk, This is Money will earn an affiliate commission. We do not allow this to affect our editorial independence. Investment platform Moneybox has launched three new actively managed ready-made funds and cut its fees for those who want to invest in them. Ready-made funds are handy for those who prefer to leave investing to experts. You just need to choose your attitude to risk based on your goals. You can buy the new funds within Moneybox's investing accounts, including its stocks and shares Isa and personal pension. Moneybox charges 0.15 per cent in account fees for these funds, as opposed to 0.45 per cent for other investments. It has also scrapped its £1 a month subscription fee for those with £5,000 or more across qualifying investing and savings accounts. Moneybox has launched the three funds in partnership with the investment manager Amundi. They have different risk profiles - cautious, balanced and adventurous. How do Moneybox's new fees compare with other platforms? Moneybox is aimed at novice investors, as well as those who might have managed investments elsewhere and are keen to cut costs. The fee cuts now make it more competitive against some of its closest rivals including AJ Bell Dodl, Monzo and Plum. You can see how the fees stack up against different platforms below: HOW DOES MONEYBOX COMPARE WITH RIVALS? | / | Annual admin charge | Choice of investments | Other notes | / | | AJ Bell Dodl* | 0.15%, minimum of £1 a month | Eight ready-made funds, selection of ETFs, UK and US shares | Part of the larger investment platform AJ Bell, founded in 1995 | / | | Moneybox | 0.15% for own ready-made funds, 0.45% otherwise | Three ready-made funds, selection of ETFs, US shares | £1 a month subscription fee on top of account fee, waived if you have £5k or more with Moneybox | / | | Monzo | 0.25% or 0.2% for paid Plus, Premium, Perks or Max account holders | Three ready-made funds, selection of themed funds (ETFs) | Capped at £250 (or £200 on paid plans). No fees on Isa or investment account if you have Aura credit card | / | | Plum* | £3.99 a month for Plus, £14.99 a month for Premium | 26 mutual funds, 3,000+ stocks | Full range of investments only available on Premium | / | | Source: This is Money, published information on providers' websites | AJ Bell Dodl* also has an annual charge of 0.15 per cent of the value of your investments and the minimum you'll pay is £1 monthly. For those with less than £5,000 to invest, AJ Bell Dodl should work out cheaper because of Moneybox's extra £1 charge on top of its platform fee. AJ Bell Dodl also has a wider range of ready-made investment portfolios, with six growth funds, one ethical fund and one pension builder fund available. However Moneybox has a broader range of financial products on offer for those who prefer to manage more of their money in one place. It offers cash savings products and has built a reputation as a champion of the lifetime Isa (Lisa). Its cash Lisa is currently sitting at a strong rate of 4.65 per cent, which includes a fixed 1.85 per cent boost for 12 months. Just beware that if you decide to transfer out of the Lisa after a year, Moneybox's terms mean that you can't then reopen it if you want to move back to the platform. This is Money says... If you're keen to start investing but aren't sure where to begin, you could do worse than Moneybox now it has cut fees on its ready-made funds. A 0.15 per cent platform charge is competitive, as is the underlying 0.29 per cent fund management fee. Taken together you'll pay 0.44 per cent a year. This is cost effective for actively managed investments aimed at beginners. Having different pricing tiers does risk creating a confusing fee structure however, which is something that legacy investment platforms such as AJ Bell*, Fidelity* and Hargreaves Lansdown* struggle with. Retaining the expensive 0.45 per cent platform charge on other investments means that Moneybox customers are more likely to choose the cheaper funds. If you are more of a do-it-yourself investor who wants a wider range of investments than Moneybox's ready-made ones, have a look at lower-cost platforms like Freetrade* and Trading 212*.

Moneybox hits $1B unicorn valuation via $57M staff share sale on London's new Pisces market

Moneybox, the UK savings and investing app, has achieved unicorn status with a valuation of £800 million ($1.1 billion). The valuation stems from a £45 million staff share sale on the London Stock Exchange's new Private Intermittent Securities and Capital Exchange System (Pisces), rather than a traditional funding round. The sale runs through Crowdcube at a fixed price, with employees selling first and an auction following in July. Access is invite-only. Founded in 2016, Moneybox serves over 1.9 million customers and holds more than £23 billion in assets. The company surpassed £115 million in revenue in 2025 and recorded its third consecutive year of profit. Pisces allows private companies to open occasional trading windows, enabling staff and early backers to cash out without a full IPO. Other companies testing the platform include Wayve and potentially Revolut.
