Technical Lead – Platform Build the Future of AI in Financial Services 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 team to meet that demand. The Opportunity We’re looking for an experienced Technical Lead to take technical ownership of the core services that underpin Aveni’s platform. This is a senior, hands-on engineering role with responsibility for the architecture, quality and operational reliability of the foundations our product teams build upon. You’ll work across areas including client-data ingestion and preprocessing, CRM integrations and APIs, multi-tenancy, identity and authentication, and data lifecycle and retention. You’ll lead the technical direction of a team of around six to seven engineers, remaining close to the code while making architectural decisions, setting engineering standards and helping other engineers grow. Our platform supports regulated financial-services organisations, so reliability, security, auditability and data isolation aren’t afterthoughts — they’re fundamental to how we design and build. What You’ll Be Doing Owning the technical architecture and direction of Aveni’s core platform services. Designing and building scalable, event-driven services on AWS. Developing and evolving our client-data ingestion capabilities, enabling new clients and data sources to be onboarded increasingly through configuration rather than bespoke engineering. Building and maintaining APIs that give Aveni products a consistent way to consume client and CRM data. Designing robust multi-tenant systems with strong data isolation, security and operational controls. Leading our approach to data lifecycle management, including retention, deletion, residency and GDPR requirements. Building resilient integrations with third-party platforms and APIs, including authentication, rate limiting, retries, reconciliation and failure recovery. Making and documenting architectural decisions and representing Core Services in Architecture Review Board discussions. Raising engineering standards across testing, observability, security, reliability and operational ownership. js and AWS. Mentoring engineers through pairing, code reviews, design discussions and technical coaching. Helping the team make effective use of AI-assisted engineering tools throughout the development lifecycle while maintaining strong engineering judgement and appropriate controls. What We’re Looking For Essential Significant software engineering experience, with a strong track record of technical leadership and architectural decision-making. js, particularly across backend, API and distributed systems. Strong experience designing and operating cloud-native systems on AWS. Experience building event-driven architectures and an understanding of the challenges that come with asynchronous distributed systems. Experience designing production systems with complex multi-tenancy, data isolation or data lifecycle requirements. Strong experience integrating with third-party APIs and designing for rate limits, partial failures, retries and reconciliation. A strong understanding of reliability, observability, security and operational ownership.
