Our partner is a leading B2B iGaming supplier delivering engaging casino content to regulated markets worldwide. Since 2012, they’ve been building high-quality gaming experiences through a modern cloud-native platform that powers hundreds of operator brands across multiple jurisdictions.

Their Platform Solutions team sits at the heart of that ecosystem, enabling seamless integrations between the company, operators, aggregators and platform providers.

They’re now growing the team and looking for a Senior Integration Manager who thrives on ownership, enjoys solving technical challenges and wants to operate at the intersection of Product, Engineering and partners.

About the Role

This is not a traditional Integration Manager or Project Manager role.

They’re looking for someone who combines strong technical understanding with excellent stakeholder management and genuine ownership.

You’ll own partner integrations from initial technical discovery through to launch and beyond, becoming the primary technical contact for your portfolio of operators and aggregators. You’ll work closely with Product, Engineering and QA while representing the company externally, ensuring integrations are delivered successfully and issues are resolved efficiently.

The role is highly cross-functional and requires someone who is equally comfortable discussing API behaviour with engineers as they are leading technical conversations with partners.

– Build trust with engineers and external partners.
– Communicate technical concepts clearly.
– Drive integrations through to completion.
– Continuously improve processes rather than simply maintaining them.

Mandatory Requirements

– Strong experience in Integration Management, Technical Account Management, Solutions
– Engineering or a similar technical customer-facing role.
– Previous experience within iGaming or another API-heavy B2B SaaS environment.
– Solid understanding of REST APIs, HTTP, JSON, authentication methods and webhooks.
– Good understanding of API testing and troubleshooting methodologies.
– Experience investigating integration issues using logs and monitoring tools.
– Understanding of networking fundamentals including DNS, SSL/TLS and connectivity
troubleshooting.
– Ability to review technical documentation and API specifications.
– Excellent communication skills and confidence working directly with engineers and external
technical teams.
– Strong ownership mindset with the ability to drive work independently.
– Fluent English.

Nice to Have
– Experience with OAuth, JWT or HMAC authentication.
– Exposure to observability tools such as Kibana, Grafana or Datadog.
– Previous software development experience.
– Experience working with cloud-native platforms.
– Leadership or mentoring experience.
– Experience improving integration frameworks, tooling or documentation.

We offer

– Work on a modern cloud-native platform serving regulated markets worldwide.

Summary

We're a growing e-commerce brand selling across 7 European markets (NL, DE, FR, ES, IT, UK, SE) on Shopify Plus. We want one person to own our entire email channel: strategy, design, and build. You're an owner, not a campaign-pusher.
 

What you'll own
 

-Email strategy: flows (welcome, nurture, win-back), campaign calendar, segmentation
-Design: sharp, on-brand templates you create yourself
-Build everything in Klaviyo across all 7 markets
-Deliverability: inbox placement, list hygiene, sender reputation
-Directing multilingual copy (via freelancers / AI, you own structure and quality)
 

You're a strong fit if you
 

-Have a strong email design portfolio and have owned email strategy (show us both)
-Can point to a case where you lifted open rate and inbox placement
-Think in flows, not one-off campaigns
-Build comfortably in Klaviyo yourself
-Work independently and document as you go
 

Nice to have

-AI tools in your workflow (Claude, ChatGPT, image generation)
-Shopify Plus and multi-market e-commerce
-Figma

We're building a greenfield high-load media platform from scratch, allowing you to shape the architecture, choose the technology stack, and make key engineering decisions from the very beginning. This isn't about maintaining legacy systems—it's about designing and delivering scalable solutions that will evolve from PoC into production

You'll tackle complex engineering challenges around WebRTC, low-latency streaming, SFU/TURN infrastructure, and scaling the platform to 300,000 concurrent connections and 3M+ requests per second.

• Design and build the infrastructure for a greenfield streaming/WebRTC platform, ensuring scalability, low latency, and high availability
• Develop and maintain CI/CD pipelines and deployment strategies to support fast and reliable releases
• Manage cloud infrastructure and Kubernetes clusters using Infrastructure as Code tools
• Implement autoscaling, performance optimization, and load testing to ensure the platform can handle high traffic and peak loads
• Build and improve the platform's observability by implementing monitoring, logging, tracing, and alerting solutions
• Optimize infrastructure for performance, reliability, security, and cost efficiency
• Collaborate closely with backend engineers and product teams, contributing to architectural decisions and the evolution of the platform

It’s all about you

• 3+ years of experience as a DevOps Engineer in production environments
• Experience designing and building high-load infrastructure from scratch
• Hands-on experience with streaming, WebRTC, or social/multimedia products
• Production experience with Kubernetes, including scaling, autoscaling, and troubleshooting

• Experience building CI/CD pipelines using GitLab CI or GitHub Actions, along with GitOps tools such as ArgoCD and Helm
• Knowledge of observability tools, including Prometheus, Grafana, logging, and distributed tracing
• Strong networking fundamentals, including UDP, RTP/RTCP, low-latency networking, and TURN/STUN (coturn)
• Experience with load testing and performance optimization for high-traffic production systems

Would be a plus

• Experience with media servers, such as mediasoup, LiveKit, Janus, or Jitsi
• Experience optimizing bandwidth-heavy streaming platforms and improving infrastructure cost efficiency
• Proficiency in scripting with Python, Go, or Bash
