• Own Azure infrastructure end to end: subscriptions, networking, edge (Azure Front Door with WAF and CDN), Azure Container Apps, ingress, secrets, identity, and the base services everything sits on • Standardise infrastructure-as-code using Terraform/OpenTofu, with all changes Git-driven, reviewable and increasingly AI-assisted • Build a self-service developer platform that abstracts infrastructure complexity so engineering teams can focus on their products: service templates, starter repos, CI/CD pipelines and deployment automation • Create the guardrails that let AI-first teams move at speed without losing control: policy-as-code, automated quality gates and security scanning in pipelines • Work closely with the Lead Architect and the Architecture Working Group on platform architecture choices and create/maintain suitable platform documentation. • Design, build and operate deep observability and alerting across the platform, so problems are spotted and triaged early • Set and operate to clear platform/infrastructure reliability and performance targets, with a proactive approach to capacity management • Lead platform incident management: act as incident commander when needed, run blameless post-mortems and make sure remediation lands • Design for high availability and disaster recovery, with rehearsed recovery procedures • Own cloud and AI cost governance: spend, environment hygiene, and visibility on model and agent usage • Own the platform security posture end to end: identity and access, network segmentation, secrets, data protection, and vulnerability management, working with the Head of IT on corporate-side controls and cross-boundary incidents • Enforce zero-trust and private-by-default across the platform: managed identities everywhere, no long-lived keys or passwords, private networking with edge-only public entry, and least privilege as the default • Embed security into pipelines and infrastructure: SAST, DAST, SCA, IaC scanning, container image scanning, secrets scanning, and policy-as-code gates that block on critical findings • Own vulnerability management and threat detection for the platform: patching SLAs, CVE triage, Microsoft Defender for Cloud, security event aggregation, and evidence for audit and compliance (Cyber Essentials, UK GDPR) in partnership with the Head of IT • Design guardrails for AI-specific security risks: prompt injection defence, agent permission boundaries, and preventing model exposure to sensitive tenant data • Manage and develop the existing DevOps team, growing it into a high-impact Platform Engineering function • Set the operating model: how the Platform team works with product squads, what it owns, and how it prioritises • Shift the culture from ticket-taking DevOps to Platform as a Product, serving internal customer teams

Role Description We are looking for an experienced Edge Platform Team Lead to drive Zyte's strategic initiative to run browsers on Edge devices. The Edge Platform Squad builds and operates browsers that power undetectable web access across cloud and edge devices. This includes engineering Zyte's end-to-end browser technology — from a custom Chromium deployed on cloud infrastructure to cross-platform browser agents running on edge devices — delivering undetectable and scalable infrastructure that enables reliable access to the most hard-to-reach data. As the Team Lead, you will be both a hands-on technical contributor and a people leader, guiding a distributed squad of engineers through complex systems challenges at the intersection of browser engineering, anti-bot evasion, networking, and distributed systems. What You Will Do - Lead, mentor, and grow a distributed team of 5–7 engineers, fostering a culture of ownership, collaboration, and technical excellence. - Own the technical direction and delivery roadmap for the Edge Platform, including sprint planning, backlog prioritization, and cross-squad coordination with other platform engineering teams. - Develop and maintain a cross-platform browser-agent application for Windows, macOS, and Android that runs on millions of devices. - Operate and evolve a large-scale gateway that connects to millions of peer devices, including node scheduling, sharding, and allocation strategies. - Build advanced stealth capabilities into the browser-agent SDK and a custom Chromium build to evade difficult antibot-protected websites, continuously identifying and eliminating bot-detection surfaces. - Develop and maintain the browser-rendering service and browser-stack microservice consumed by the API squad, providing a robust interface for routing requests. - Keep the custom Chromium branch current with every official release cycle. - Provide a sandboxed runtime for product teams to deploy site-specific logic, and support the CDP proxy layer for integration with headless browser frameworks (Selenium, Puppeteer, Playwright). - Drive architectural decisions through RFDs (Requests for Discussion). - Own KPIs related to antiban success rates, website coverage, and system reliability; report on team performance against defined deliverables. - Collaborate with Product, QA, and DevOps stakeholders to ensure quality, observability, and operational readiness of all Edge services. Qualifications - 10+ years of software engineering experience, with at least 3 years in a team lead or tech lead role managing distributed engineering teams. - Strong systems programming skills in one or more of: C++ or Rust, with experience building high-load, latency-sensitive services. - Strong understanding of networking protocols (HTTP/1.1, HTTP/2, HTTP/3, WebSockets, TLS) and network programming. - Strong knowledge of event-driven and asynchronous programming patterns (event loop, futures, reactor patterns). - Proficiency with containerization and orchestration: Docker, Kubernetes, and cloud platforms (GCP, AWS). - Excellent communication skills in English and experience leading remote-first, globally distributed teams. - Computer Science degree or equivalent working experience. Requirements - Experience with CI/CD pipelines, observability tools, and operational best practices for production services. - Experience with distributed systems architecture: command-and-control patterns, peer-to-peer networking, node scheduling, and sharding. - Hands-on experience with Chromium development, building custom browser forks, or contributing to browser engine projects. - Experience with win32 API. - Experience with cross-platform desktop or mobile application development (Windows, macOS, Android). - Deep knowledge of browser internals, the Chromium codebase, or browser automation frameworks (Puppeteer, Playwright, Selenium, CDP). - Knowledge of anti-bot detection systems and evasion techniques (fingerprinting, TLS signatures, behavioral analysis). - Experience with web scraping or web data extraction at scale. - Familiarity with the Quiche networking library or custom networking stacks. - Apache Kafka or similar event streaming platforms experience. - Track record of driving architectural decisions through RFC/RFD processes. - History of open-source contributions. Benefits - Become part of a self-motivated, progressive, multi-cultural team. - Have the freedom & flexibility to work remotely. - Get the chance to work with cutting-edge open source technologies and tools.
