About the role.

As a Principal Solutions Architect at Solo.io, you’ll be responsible for delivering technical projects that ensure our customers get the maximum value out of our offerings. While product onboarding and adoption is a core focus, responsibilities include help with migrations, feature adoption and any technical problem whose scope is larger than what can reasonably be worked through a support ticket. Our customers are some of the most knowledgeable platform engineers and software developers in the world, and your job is to work with them on how to best architect solutions using Solo products. 

• Serve as the primary technical point of contact for a small portfolio of strategic accounts based in EMEA, developing deep familiarity with their use cases, architecture, teams, and business goals.
• Lead technical issue resolution end-to-end, partnering with Support and Engineering on escalations and driving root-cause analysis. Provide hands-on troubleshooting within your accounts where it accelerates resolution and deepens customer trust.
• Guide customers as they extend Solo.io products to support modern workloads — including AI and agentic use cases such as LLM gateways, agent-to-agent communication, and securing model traffic at scale.
• Proactively drive product adoption by identifying new use cases and surfacing opportunities for customers to gain more value from the Solo.io product suite.
• Consult with customers on architectural best practices, performance tuning, and operational excellence in their Solo.io deployments.
• Design and deliver tailored training sessions, workshops, and enablement content to grow customer self-sufficiency.
• Champion the customer inside Solo.io — translating their needs into actionable feedback for Product Management and Engineering.
• Partner with the account team (CSM, AE, SE) to identify and manage technical risk, renewal health, and expansion opportunities.

• 5+ years in a customer-facing technical role such as Solutions Architect, Customer Success Engineer, Site Reliability Engineer, or Senior Support Engineer.
• Deep expertise in cloud-native technologies, including Kubernetes, service mesh (e.g., Istio, Cilium), and API gateways and proxies (e.g., Envoy, Gloo Gateway).
• 1+ years of hands-on experience with AI/ML technologies — LLMs, agentic frameworks, model-serving platforms, or AI infrastructure.
• Proven track record managing technical relationships with large, strategic enterprise customers in a post-sales context.
• Excellent troubleshooting instincts and the ability to navigate complex, multi-team production environments.
• Strong communication and presentation skills, with the ability to translate complex technical concepts for audiences ranging from platform engineers to senior executives.
• Comfort with scripting or programming (e.g., Go, Python, Bash) for diagnostics, automation, and reference implementations.
• Bachelor's degree in a technical field, or equivalent industry experience.

We are primarily focused on applicants authorized to work in the UK, Spain, Germany, Slovakia, Slovenia, or Hungary now and in the future as Solo is unable to provide visa sponsorship. However, exceptionally strong technical candidates from other EMEA locations may be considered.
