As a Network & Connectivity Solution Architect reporting to the VP of Software Engineering, you'll play a critical role in designing and governing the end-to-end network and connectivity architectures that power the Calypso CapCloud platform — a cloud-native capital markets solution serving clients across global financial markets. You'll thrive in this position if you're technically deep, client-focused, and energized by solving complex connectivity challenges across cloud, hybrid, and on-premises environments. You bring a global mindset, a passion for cloud networking and security, and the ability to translate complex architecture into clear, actionable outcomes. Key Responsibilities Lead the design of scalable, secure network and connectivity architectures for the CapCloud platform, spanning cloud-native, hybrid, and on-premises environments across AWS and Oracle Cloud Infrastructure (OCI). Serve as the primary technical advisor for customer connectivity and integration architecture, leading discovery workshops, design reviews, and onboarding engagements with clients and implementation partners. Define and maintain connectivity reference architectures, solution blueprints, and design standards — covering private connectivity, VPNs, APIs, load balancing, proxy architectures, and traffic management. Architect and govern enterprise PKI, TLS/mTLS, and Zero Trust networking solutions, ensuring compliance with X.509, RFC 5280, and PKIX standards. Lead adoption of Infrastructure as Code (IaC) practices using Terraform and cloud-native automation, standardizing connectivity deployment patterns and integrating networking into CI/CD pipelines. Required Qualifications Several years of experience in network architecture, cloud networking, or connectivity engineering, with hands-on expertise across AWS (preferred) and/or OCI environments. Proven ability to design end-to-end network solutions including VPC/VCN architectures, BGP/OSPF routing, VPN technologies (IPsec, FortiGate), and private connectivity services (AWS Direct Connect, OCI FastConnect, AWS PrivateLink). Strong experience with traffic management technologies including Layer 4/7 load balancers, HAProxy, Squid Proxy, SSL termination, and reverse proxy architectures. Demonstrated experience with Kubernetes networking, service mesh architectures (mTLS, East-West traffic), and API gateway standards (authentication, rate limiting, developer onboarding). Clear communicator with a track record of presenting architecture recommendations to both technical teams and senior stakeholders. Preferred Qualifications Cloud networking certifications (e.g., AWS Advanced Networking Specialty, OCI Networking) or equivalent experience. Experience in capital markets, fintech, or regulated financial services environments. Familiarity with connectivity protocols used in financial markets, including FIX connectivity, IBM MQ, market data distribution, and third-party trading and clearing platforms. This position is based in London and offers a hybrid work environment with at least 3 days per week in-office, subject to change.
