Senior Software Engineer - Chats Stream

Fanvue is the fastest-growing creator monetisation platform in the creator economy. We are the leading AI-powered creator-first platform, designed to empower creators worldwide to directly monetise their audience. We’re on a mission to redefine the creator economy by empowering creators to connect, share, and earn more efficiently.

🎯 The Role
We’re hiring a Senior Software Engineer to join the Chats stream — Fanvue’s most critical monetisation engine. You will be one of the key owners of our real-time chat platform, responsible for building and scaling the systems that drive creator–fan interactions, AI-native features, and high-volume transactional messaging.

This role exists because we currently have a single engineer supporting this mission-critical stream. Bringing in a second expert ensures continuity, unlocks new monetisation capabilities, and accelerates our ability to ship high-impact features.

🚀 What You’ll Do

• Design, develop, and maintain Fanvue’s real-time, stateful Chat Service at scale

• Own and evolve internal event-driven APIs that connect chat data to monetisation, user, and AI systems

• Instrument, monitor, and continuously improve performance across latency, throughput, and concurrency

• Architect the foundational data and API layers required for Always-On AI features (translation, summarisation, agentic workflows)

• Write clear, rigorously engineered design documents and contribute to high-quality code reviews

• Partner closely with Product to build new social and monetisation features such as reactions, in-chat tipping, and unlockable content

• Collaborate with SRE to define infrastructure, monitoring dashboards, and scaling strategies for peak creator usage

• Act as a technical leader within the team, improving engineering practices and mentoring others

👀 Who You Are
A highly skilled backend or distributed-systems engineer with deep experience building low-latency, high-throughput, real-time services. You think in systems, care about performance at scale, and understand the business impact of every architectural decision. You bring:

• Strong background in real-time, distributed system development (WebSockets, gRPC, streaming architectures)

• Ability to design scalable, fault-tolerant systems from first principles

• Product-minded engineering instincts with an understanding of user value and monetisation

• High ownership mentality with a pragmatic, outcome-driven approach

• Experience debugging complex performance issues using tools like Prometheus, Grafana, or DataDog

• Mastery of backend languages such as Go, Node.js, or C#, and strong API design experience across REST and event-driven systems

• Excellent communication skills and the ability to articulate complex technical trade-offs clearly

Nice-to-haves

• Experience working in creator platforms, chat products, or AI-enabled systems

• Familiarity with NoSQL and in-memory data stores like Redis or DynamoDB

• Prior experience building monetisation primitives or transactional messaging features

✨ You’ll Thrive Here If

• You love solving complex engineering problems at scale

• You think in terms of systems, observability, and high availability

• You enjoy collaborating closely with product teams to build user-facing value

• You want to own huge technical surfaces with autonomy and accountability

⚠️ You’ll Struggle Here If

• You prefer slow-moving environments or lack of accountability

• You are uncomfortable with deep architectural ownership

• You do not enjoy performance, scalability, or distributed systems challenges

🌍 Why Join Fanvue?

• Own one of the highest-impact engineering surfaces in the company

• Competitive salary, equity, and benefits package

• A culture that values innovation, ownership, transparency, and speed

• Unlimited holiday

• Remote working

• Flexible hours, according to when you perform best

• Budget for growth and wellbeing
