• Data modelling and XDM: Strong ability to design and implement Experience Data Model (XDM) schemas for multi-channel marketing use cases. Ability to map source-system fields to XDM, define identity namespaces, and model profile and experience event data correctly.
• SQL and data querying: Strong SQL proficiency for querying datasets, writing complex joins and aggregates, applying filter conditions, transforming data, and working within AEP Data Distiller or similar query environments.
• API development and integration: Hands-on experience integrating with AEP and AJO REST APIs, designing custom actions, configuring webhooks, working with JSON payloads, managing OAuth or IMS authentication, and validating with Postman or similar tooling.

• Segmentation and audience design: Practical experience creating and validating rule-based segments, computed attributes, AI/ML-powered audiences, and multi-channel activation strategies 

  grounded in profile and behavioural data.

• Customer communication and advisory: Ability to engage enterprise customers independently, articulate solution recommendations clearly, lead discovery workshops, and present technical designs to both technical and business stakeholders with confidence.
• Basic AI and agentic skills: Working understanding of AI-assisted delivery, prompt engineering, agentic workflows, and responsible use of AI tools to improve discovery, documentation, testing, troubleshooting, and implementation productivity.

• End-to-end delivery ownership: Demonstrated ability to own AJO/AEP workstreams from requirements gathering through go-live, including documentation, testing, and post-launch support, with limited supervision.

What you'll do

• Consulting and requirement discovery: Engage with customers to understand business goals, technical requirements, pain points, success criteria, and current-state architecture. Conduct discovery workshops, gather inputs from business and technical stakeholders, and translate needs into clear implementation scope and recommendations.
• Solution design and roadmap: Recommend solution architecture, implementation approach, phasing, and best practices aligned to customer objectives. Design data models, data flows, segmentation logic, personalisation rules, journey patterns, and integration touchpoints.
• Adobe Journey Optimizer delivery: Implement and configure journey orchestration, events, triggers, conditions, wait logic, automations, custom actions, messages, and offers in Adobe Journey Optimizer. Ensure journeys are scalable, testable, maintainable, and aligned to approved business use cases.
• Offer and experience decisioning: Configure and implement AJO decisioning capabilities including decision items, offers, collections, eligibility rules, ranking logic, placements, and decision policies to deliver relevant content and offers across channels.
• Web, in-app, and code-based experiences: Design and implement personalised web, in-app, content card, push, email, SMS, and code-based experiences using AJO, AEP data, Web SDK, Mobile SDK, Edge Network patterns, HTML, CSS, and personalisation syntax where applicable.
• Content personalisation and experimentation: Build personalised content experiences using fragments, templates, dynamic content, contextual attributes, profile data, audience rules, and decisioning outcomes. Support experiments, testing, and optimisation to improve engagement and customer experience.
• Data engineering and integration: Design, build, and optimise data ingestion flows from CRM, web, mobile, file-based, and external systems into AEP. Ensure data moves accurately and reliably across source systems, journeys, destinations, and reporting use cases.
• Data modelling, segmentation, and identity: Design and implement XDM schemas, datasets, identity mappings, profile attributes, audience rules, joins, filters, aggregates, and segmentation logic using SQL and data modelling best practices.
• Customisation and API development: Develop custom scripts, extensions, custom actions, and API first integrations using JavaScript, SQL, Python, and REST APIs. Validate integrations, payloads, authentication, and error handling using Postman or similar tools.
• Troubleshooting and optimisation: Diagnose, debug, and resolve technical issues across data ingestion, identity, APIs, schemas, audiences, journeys, content rendering, delivery, synchronisation, and performance. Proactively optimise implementations for reliability, scalability, and operational efficiency.
• Quality assurance and validation: Partner with QA, business, and technical teams to define test scenarios, validate data flows and journey behaviour, support user acceptance testing, and ensure solution quality, stability, and readiness before go-live.
• Post go-live support: Provide production support, enhancements, maintenance, upgrades, defect resolution, and operational guidance after launch to help customers stabilise and continuously improve their implementations.
• Documentation, enablement, and coaching: Create and maintain solution designs, technical documentation, configuration notes, runbooks, and knowledge transfer materials. Conduct product training, customer walkthroughs, and best-practice sessions to improve adoption.
• Delivery coordination: Collaborate with project managers, architects, consultants, engineering teams, and customer stakeholders to manage timelines, milestones, dependencies, risks, deliverables, and regular status updates.
