Lead Solutions Engineer Engineering Team Copenhagen, London-Fitzrovia House

Are you a seasoned integration architect who thrives on solving real-world complexity at scale? Do you love the challenge of designing plugin systems, auth flows, and resilient APIs that power mission-critical financial infrastructure? We'd love to hear from you.

Join us as a Lead Solutions Engineer - Integrations & Plugins and help shape the extensibility and integration foundation for Europe's modern wealth platform. Get ready to build, architect, and influence at scale-with clarity and deep technical ownership.

As our new Lead Solutions Engineer, you will

• Own the integration experience - design and evolve extensibility patterns across auth, data ingestion, and event-based systems

• Be hands-on - build prototypes, scaffolds, and SDK touchpoints in TypeScript, Python, or Go

• Lead architecture - run discovery and go-live discussions with our largest clients and integration partners

• Shape our plugin strategy - define how third parties (and internal teams) build on top of the Performativ platform

• Align our teams - ensure product, platform, and delivery operate from shared, scalable blueprints

• Define the "how" - own the implementation path while working closely with product to clarify the "why"

What we're looking for

• 7+ years of experience in software engineering or integration/system architecture

• Proven track record in API-first integration design, OAuth2/SAML auth flows, and plugin/iPaaS ecosystems

• Strong programming skills in TypeScript, Python, or Go

• Familiarity with AWS-native services (API Gateway, EventBridge, SQS)

• Enterprise client experience - you can explain complex systems clearly, under pressure, in front of stakeholders

Bonus points for

• Designing SDKs, plugin frameworks, or developer tooling ecosystems

• Experience in fintech, wealthtech, or regulated domains

• Contributions to open-source platforms or developer experience tooling

In return, success in this role looks like

• Seamless client onboarding without integration sprawl

• Plugin systems that accelerate-not constrain-platform adoption

• Clear boundaries between where platform ends and customization begins

• Scalable, secure integrations that meet enterprise requirements and evolve with us

What we offer

Competitive salary + equity
Hybrid-friendly setup with high autonomy
30 days of paid annual leave
Hardware & learning stipends
Direct access to engineering, product, and leadership
High-trust, high-ownership culture with real impact at every level
