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.\nWe 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.\nOur 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.\nThe Role\nAs a Senior 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.\nYou 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.\nYour work will focus on:\nDesigning and implementing robust event-driven microservices and APIs\n\nBuilding scalable, cloud-native systems on AWS\n\nDeveloping modern, responsive React front-ends\n\nIntegrating LLM-powered capabilities into real-world workflows\n\nCollaborating closely with product and AI specialists to turn ideas into reliable, customer-ready features\n\nWhat you’ll be working with\nYou should be comfortable with most of our core technologies:\nNode.js and TypeScript\n\nReact and modern front-end tooling\n\nAWS (e.g., Lambda, ECS/Fargate, API Gateway, SQS/SNS, DynamoDB, RDS)\n\nNestJS or equivalent back-end frameworks\n\nMicroservices and event-driven architectures\n\nWe 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.\nWhat we’re looking for:\nExperience building production systems using Node.js / TypeScript\n\nHands-on experience developing UIs with React\n\nSolid understanding of cloud-native engineering on AWS\n\nExperience with microservices, messaging patterns and distributed systems\n\nA commitment to clean code, testing, observability and operational excellence\n\nA proactive and motivated mindset - someone who wants to build, ship and iterate quickly\n\nInterest in AI-powered products and a drive to learn\n\nBenefits at Aveni\nWhat you’ll love\nRemote-first working across the UK.\n\nWork abroad policy for when you want a change of scenery.\n\nCo-working spaces available if you want an office buzz sometimes.\n\n34 days holiday (including flexible bank holidays) and your birthday off.\n\nCompany-wide off-sites (yes, karaoke may happen).\n\nOptional Personal Development Plan.\n\nFlexible benefits platform: you choose the benefits that matter most to you (not the company).\n\nProtection essentials, because we know they matter - Life Insurance, Income protection, critical illness cover, Pension (up to 5% matched employer contribution and optional increased contributions).\n\nPrivate health- and dental care for your peace of mind.\n\nPotential share options, have a stake in what you’re building.\n\nEnhanced family leave.\n\nJoin Us in Making a Difference\nAt 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.\nEven if you don’t meet 100% of requirements, we’d like to hear from you anyway if you believe you’d fit in.
