About the Opportunity

We are hiring a Senior Personalization Solution Architect with deep domain expertise in personalization and experimentation to join Contentful’s Professional Services team. This role is designed for a practitioner who has built, operated, and scaled personalization programs in production, and who also brings the hands-on technical skills required to implement those programs in modern, composable architectures.

This is not a generalist Solution Architect role with light exposure to personalization. Success in this role requires strong opinions and real-world experience across audience strategy, decisioning, experimentation, and measurement—paired with the ability to design and deliver high-quality technical implementations using Contentful Personalization.

You will work directly with customer engineering, product, and marketing teams to design and implement advanced personalization and experimentation solutions, while also serving as a customer-facing extension of Contentful’s Product and Engineering teams. Your work will help reduce implementation risk, accelerate time to value, and create tighter feedback loops into product development—specifically for complex personalization use cases.

What to expect? 

Personalization & Experimentation Domain Leadership 

• Own the end-to-end design of personalization and experimentation programs, including:
• audience and segmentation strategies grounded in behavioral, contextual, and first-party data

• Design personalization strategies that scale responsibly, including:
• guardrails to prevent over-personalization, bias, and degraded user experience
• approaches for global, multi-brand, or multi-region deployments
• tradeoffs between targeting precision, latency, and operational complexity
  
  
• Define measurement approaches that connect:
• user behavior → decisioning logic → exposure → business outcomes
  
  
• Act as a domain authority for personalization and experimentation in customer engagements, confidently guiding technical and non-technical stakeholders through best practices, limitations, and tradeoffs.

Technical Solution Architecture & Hands-On Delivery

• Architect and implement end-to-end personalization solutions using Contentful Personalization, including:
• user identification and profile stitching
• audience evaluation and decisioning
• personalized content and experience delivery
  experimentation and uplift measurement
  
  
• Lead hands-on implementation activities such as:
• building proof-of-concepts and reference implementations
• configuring personalization models and decision logic
• developing integration services and APIs

• CDPs (Segment, Tealium, mParticle, etc.)
• CRMs (Salesforce, Dynamics)
• analytics platforms (GA4, Adobe Analytics, Snowplow)
• identity, consent, and privacy tooling
  
  
• Design personalization delivery patterns across modern rendering strategies:
• SSR, CSR, SSG, ISR
• edge and CDN-based personalization
• hybrid static + runtime personalization approaches
  
  
• Ensure solutions meet enterprise requirements for:
• performance and scalability
• reliability and fallback behavior
• security and privacy compliance

Technical Discovery & Customer Enablement

• Lead technical discovery sessions to assess customer readiness across:
• data quality, identity maturity, and event instrumentation
• architectural constraints (latency, caching, edge delivery)
• content model alignment and operational workflows
  
  
• Translate personalization requirements into detailed technical designs, including:
• integration patterns and API contracts
• data and event schemas
• deployment and observability considerations
  
  
• Enable customer teams through:
• implementation workshops and pair-programming
• architecture and code reviews
• developer documentation and operational runbooks

Cross-Functional Collaboration & Feedback Loops

• Partner closely with Contentful Product and Engineering teams to:
• surface implementation challenges and recurring customer pain points
• provide feedback that influences roadmap, developer experience, and documentation
• validate new personalization capabilities against real customer use cases
  
  
• Contribute to internal enablement by:
• mentoring Solution Architects and delivery team members
• developing reusable accelerators, patterns, and reference architectures
• supporting Sales and Solution Engineering with technical expertise in complex personalization opportunities

What you need to be successful?

Required: Personalization & Experimentation Domain Expertise

• Demonstrated, hands-on experience designing and operating personalization and experimentation programs in production, including:
• ownership of audience strategy and decisioning logic
• designing and running A/B or multivariate experiments beyond basic UI testing
• interpreting experiment results and translating them into iterative improvements
  
  
• Strong understanding of personalization challenges such as:
• identity resolution and anonymous vs known users

When the Space Shuttle approached the International Space Station, two vehicles built by different teams, in different countries, with fundamentally different engineering philosophies and systems, had to connect perfectly. The Rendezvous, Proximity Operations, and Docking (RPOD) subsystems were engineered to handle complex mismatches such as different power systems, communication protocols, and technical architectures. Get it wrong, and you have an expensive and potentially catastrophic problem in low Earth orbit.

Mercury announced on December 19, 2025 that we submitted an application to the OCC for a national bank charter and applied for FDIC deposit insurance. In other words, Mercury is building a bank. As part of this work, we will be connecting our modern, product-focused engineering systems to enterprise core banking systems and payment networks built in a different era, with different assumptions and different interfaces. Mercury’s Banking Integration Platform as a Service team is like NASA’s RPOD team, building our integration subsystems that are technically correct and operationally trustworthy.

This is some of the most consequential infrastructure work at Mercury. Every account opening, every monetary transaction, and every balance call will flow through the systems you build. Product teams across the company will depend on clean abstractions that hide the complexity underneath. You'll be one of the few engineers at Mercury who truly understands the full depth of our Bank Core* and all its internal and external integrations.

In this role, you will:

• Build Mercury’s integration with an FFIEC-approved bank core and the connections to payment networks.
• Design internal APIs that give product teams simple, consistent interfaces to complex external systems.
• Handle the messy realities of enterprise integrations such as retries, failures, format mismatches, and downtime.
• Build data pipelines that keep Mercury's systems in sync with our bank core.
• Own monitoring, alerting, and recovery for our most critical external connections.
• Partner with many other teams at Mercury to define clean boundaries and reliable contracts.
• Help shape the technical architecture of Mercury Bank*.

You should:

• Have direct experience with either a bank core that has achieved FFIEC-compliance (such as FIS) or that of a US-based Global Systemically Important Bank (G-SIB) .
• Understand how core banking systems work: accounts, transactions, ledgers, and the data models underneath.
• Be a product-minded engineer who thinks about the developers consuming your APIs, not just the systems you’re connecting to.
• Thrive in environments where you're building something new rather than maintaining something established.
• Be comfortable with our tech stack (Haskell and TypeScript) or ready to learn.
• Have strong opinions about building reliable, maintainable systems.
