Technical Lead - PaaS Platform | Hybrid (Central London)

83zero is proud to partner with a high-growth startup that's redefining the B2B2C social media space. They're building a next-generation Platform-as-a-Service already making waves across global media ecosystems - and now they need a DevOps Leader to help scale it to the next level.

Why This Role?

This isn't just another leadership position. You'll own the technical vision for a serverless, event-driven, globally distributed platform on AWS. You'll lead a talented, distributed engineering team, shape high-performance APIs, and build systems that scale fast and run clean.

What's On Offer

• Competitive salary + performance bonus
• Meaningful equity - build it, own it, grow with it
• Hybrid/remote-first working culture
• A seat at the decision-making table in a fast-scaling SaaS business
• Real autonomy, rapid progression, and zero bureaucracy
• A culture of experimentation, curiosity, and bold thinking

Your Mission

As DevOps Lead, you will:

• Architect and optimise a high-scale, cloud-native PaaS
• Drive CI/CD, automation, observability, and reliability
• Design and maintain secure, performant public APIs
• Build real-time, distributed systems on AWS (Lambda, DynamoDB, Kinesis, ECS/EKS)
• Mentor a cross-functional team and raise engineering standards
• Prototype and ship features that deliver commercial impact - including mobile apps and PWAs

What You'll Bring

Essential:

• 7+ years in software engineering, with 3+ years in DevOps or Technical Lead roles
• Experience building both front-end apps and backend dashboards
• Deep expertise in serverless/event-driven architecture on AWS
• Mastery of CI/CD, Agile delivery, and containerisation (Docker, Kubernetes)
• Proven leadership of distributed engineering teams

Desirable:

• Background in social media, advertising, eCommerce, or news
• Proficiency in Node.js, Go, Python, Java, and modern front-end frameworks
• AWS certifications, microservices/service mesh, and streaming tech (Kafka/Kinesis)
