Aveni UK
Edinburgh, Midlothian
Aveni is redefining how financial institutions use AI. We build real, production-ready agentic systems that reshape how banks, advisers and financial services firms operate, replacing fragmented processes with intelligent, end-to-end workflows. We have been recognised as Fintech of the Year for two consecutive years and awarded Best Specialist Technology Service at the Professional Adviser Awards 2025. Backed by leading investors including Puma Private Equity, and commercially supported by Lloyds Banking Group and Nationwide Building Society, we previously completed one of Scotland's largest Series A rounds. Since then, we've continued to grow rapidly as adoption of AI in financial services accelerates, and we're now scaling our engineering organisation to meet that demand. Our engineering team includes experienced software engineers and PhD-level AI specialists, with strong ties to the University of Edinburgh, giving you access to exceptional expertise and opportunities for continuous learning as part of the day-to-day work. The role We're looking for a Staff Engineer to be the most senior technical voice in one of our product squads, working as a technical co-leader alongside the Engineering Manager. You'll own the squad's technical direction and engineering quality end to end, from architectural decision making and hands on delivery, to mentoring engineers and shaping how we build across the organisation. This role demands genuine depth in AI. You'll be leading LLM powered feature development and setting the standard for how AI tooling amplifies the whole engineering process, combined with the full stack and cloud native chops to back it up. What you'll be doing Setting technical direction for your squad. Owning architectural decisions, managing technical risk, and representing the engineering perspective at our Architecture Review Board Leading AI powered product development: designing LLM workflows, RAG pipelines, and agentic features that run on top of our AI platform in production, at scale Driving adoption of AI coding tools across the full SDLC, from planning and design through code review, testing, deployment and setting the bar for how the squad works Delivering production grade code across the full stack: Node.js or Python backends, event driven AWS architecture, and React where the squad needs it Mentoring and growing engineers across AI and full stack domains, through code reviews, design documents, and day to day pairing Collaborating with platform teams to consume shared capabilities and contribute reusable patterns back, not building one off solutions when a platform component will do Ensuring everything we ship is compliant by design, auditable, and built to the standards expected of software in FCA regulated financial services Requirements What we're looking for A seasoned engineer with 10+ years of experience, including meaningful time building and operating AI/ML systems in production Real technical leadership. You've set direction, made architectural calls, mentored others, and influenced how a team builds, not just what it ships Strong hands on AI/LLM skills: prompt engineering, RAG, model evaluation and agent frameworks. You know how these work in production, not just in demos Deep expertise in Node.js or Python, with solid experience in the other; comfortable switching contexts depending on what the problem needs Cloud native development on AWS. Serverless, event driven, Lambda, with an instinct for well designed, maintainable systems A genuine curiosity about where AI is going and the judgment to separate signal from noise when recommending what to adopt An instinct for building responsibly. You care about auditability, compliance, and the downstream impact of what you ship Why Aveni You'll work at the frontier of applied AI in a domain where it actually matters, helping financial services firms serve their clients better and meet growing regulatory obligations AI native engineering culture: we use AI tools seriously, across the full development process, and we're always looking to push further High impact from day one. As a Staff Engineer, your technical decisions will shape the product, the platform, and the engineers around you A talented, collaborative team building something genuinely novel, with the backing, the architecture, and the proprietary models to do it properly Benefits at Aveni What you'll love Remote first working across the UK. Work abroad policy for when you want a change of scenery. Co working spaces available if you want an office buzz sometimes. 34 days holiday (including flexible bank holidays) and your birthday off. Company wide off sites (yes, karaoke may happen). Optional Personal Development Plan. Flexible benefits platform: you choose the benefits that matter most to you (not the company). Protection essentials, because we know they matter - Life Insurance, Income protection, critical illness cover, Pension (up to 5% matched employer contribution and optional increased contributions). Private health and dental care for your peace of mind. Potential share options, have a stake in what you're building. Enhanced family leave. Join Us in Making a Difference At Aveni, we believe that diversity drives innovation. We've built our business to ensure an inclusive workplace where everyone feels valued and empowered to contribute their best work. If you're passionate about technology and its ability to drive positive change for the future of financial services, we'd love to hear from you. Even if you don't meet 100% of requirements, we'd like to hear from you anyway if you believe you'd fit in.

The Role As a Software Engineer at Aveni, you'll be responsible for building and scaling the products that sit on top of FinLLM (the UK's first LLM for the Financial Services industry) and other LLMs, enabling financial institutions to adopt AI safely and effectively. You won't be expected to build or train the LLMs themselves, instead you'll be engineering the platforms, services, user interfaces and integrations that bring those models to life in the hands of advisers, analysts and banking teams. Your work will focus on: Designing and implementing robust event-driven microservices and APIs Building scalable, cloud-native systems on AWS Developing modern, responsive React front-ends Integrating LLM-powered capabilities into real-world workflows Collaborating closely with product and AI specialists to turn ideas into reliable, customer-ready features What you'll be working with You should be comfortable with most of our core technologies: Node.js and TypeScript React and modern front end tooling AWS (e.g., Lambda, ECS/Fargate, API Gateway, SQS/SNS, DynamoDB, RDS) NestJS or equivalent back end frameworks Microservices and event driven architectures We also actively embrace AI coding assistants (such as Claude Code) to speed up development, improve code quality and reduce repetitive work - and we encourage engineers to use these tools effectively. Requirements What we're looking for: Experience building production systems using Node.js / TypeScript Hands on experience developing UIs with React Solid understanding of cloud native engineering on AWS Experience with microservices, messaging patterns and distributed systems A commitment to clean code, testing, observability and operational excellence A proactive and motivated mindset - someone who wants to build, ship and iterate quickly Interest in AI powered products and a drive to learn What you'll love Remote first working across the UK.
