Job description

About the role (£50k-£70k + equity)

At Ask Silver, you’ll be helping to tackle one of the most meaningful, but also hardest, problems in society; scams.

Every year, millions of people are socially engineered and fall victim to fraud.

My dad (I’m Alex, one of the co-founders) was scammed out of most of his life savings, almost £150,000, a few years ago and we’ve spoken to hundreds of victims and their family members.

We’re building human-centred technology to keep people safe from scammers 🛡️.

Our tools are free for consumers, and paid for by organisations like banks, businesses and governments that face a huge cost in scams.

We launched our AI-powered Scam Checker just over a year ago and have already been featured in the BBC, ITV, Daily Mail and hundreds of other media outlets 🗞️. We already signed Metro Bank PLC as our first customer and are onboarding some of the biggest banks in the UK 🏦.

As our fourth engineer, you’ll have a huge amount of autonomy to shape what we build and how we build it. From launching new features to experimenting with smarter ways to catch scams, you’ll be solving tricky problems that matter and helping people avoid the stress and heartbreak that scams can cause.

What you’ll do 🛠️

• Design, build, and maintain scalable backend services and APIs for our core AI products
• Build and maintain our front end widgets, dashboards and website
• Build robust data processing pipelines and integrations with financial platforms
• Adhere to best practices in security, data handling, and privacy
• Write clean, well-tested code (primarily in Python or TypeScript)
• Build LLM systems, experiment, prompt, cutting-edge techniques

What we’re looking for 🌟

• 2+ years of experience as a software developer
• Strong skills in Python or TypeScript
• Experience building and maintaining fault-tolerant systems

Bonus points ➕

• Startup experience
• Passion projects or personal projects where you’ve built and shipped something end-to-end
• FinTech or financial services experience
• Familiarity with LLM or ML integration in production environments
• Experience with Django (backend) and React (frontend)
• Experience working on or developing public APIs

What we value ❤️

End-to-end ownership 🛠️

You don’t just wait to be told what to do, you’re invested in building a great product and take full responsibility for delivering value. You always have an idea to tinker with or a bug you’ve spotted that needs some love.

Pragmatic problem-solving 🧩

You enjoy complex challenges and you’ve got excellent attention to detail when it matters but you also understand when things need to get shipped quickly and a little more scrappily.

Collaboration 🤝

You work closely with founders and teammates. You’re comfortable jumping between product conversations, fast-moving experiments, and careful engineering reviews.

Initiative ⚡

You spot opportunities to improve the product or platform and take action without needing to be asked.

Curiosity and adaptability 🌱

You’re keen to explore new ideas, technologies, and ways of working. You welcome feedback, challenge assumptions, and grow with the company as it evolves.

User focus 👥

We build for people first and foremost. You should care deeply about the user experience and want to build tools that genuinely make a difference.
