Job description

Take a leading role in modernising enterprise integration, combining architecture ownership with hands‑on engineering across Boomi, Kafka and AWS.

This senior individual contributor position offers the opportunity to influence technical decisions across multiple projects, build complex integrations and help engineering teams adopt consistent, reusable practices. You will own production quality and reliability alongside delivery, with participation in a defined Tier‑3 on‑call rotation.

What you’ll do

• Translate business requirements into secure, scalable and resilient integration architectures, agreeing clear acceptance criteria with stakeholders.
• Design, build, test and deploy API, application‑to‑application, file‑based, B2B and event‑driven integrations.
• Establish reusable Boomi components, mappings, API contracts and patterns for error handling, recovery, deployment and runtime management.
• Guide Kafka engineering on Amazon MSK, covering partitioning, producers and consumers, delivery semantics, Kafka Connect, schema evolution, security, capacity and cross‑cluster recovery.
• Improve delivery through automated testing, performance checks, deployment pipelines, configuration management and rollback procedures.
• Coordinate technical work across projects, review designs and code, mentor engineers and resolve dependencies, priorities and scope conflicts.
• Define meaningful monitoring, service objectives, runbooks and recovery procedures with service owners. Lead complex troubleshooting and turn root‑cause findings into engineering improvements.
• Shape platform roadmaps through capacity planning, cost analysis, prototypes and technology evaluations, presenting recommendations to senior stakeholders.

What you’ll bring

Extensive Boomi and Kafka expertise

You will need deep practical experience with both platforms. Your Boomi background should cover architecture, process design, connectors, transformations, APIs, testing, deployment, performance and runtime administration.

Your Kafka experience should include production ownership, partitioning, replication, consumer groups, offsets, delivery semantics, tuning, Kafka Connect, schema compatibility, access controls and capacity planning. Experience implementing cross‑cluster replication or mirroring and validating recovery procedures is essential.

Cloud engineering and automation

You will have hands‑on AWS experience supporting integration or streaming workloads, with working knowledge of IAM, networking, encryption and security controls. Amazon MSK experience is preferred; comparable managed Kafka experience is suitable when supported by AWS proficiency and the ability to apply that knowledge to MSK.

You should also bring strong scripting skills in Python, Bash, PowerShell or a comparable language, alongside experience building repeatable delivery pipelines, automated integration and API tests, performance tests and release quality checks.

Technical leadership and operational ownership

You will be comfortable making architecture decisions independently, resolving ambiguous requirements and balancing security, availability, scalability, recovery and cost. Experience guiding delivery across multiple large projects, mentoring engineers and communicating with senior leadership is essential.

Your background should include observability, service‑level objectives, incident and release management, capacity forecasting and cost‑of‑ownership analysis. Experience with Jira, ServiceNow or equivalent tools is relevant.

You must be able to collaborate with globally distributed teams and participate in a defined Tier‑3 on‑call rotation covering weekdays and weekends.

Experience and education

• 7+ years of IT‑related experience with a bachelor’s degree, or nine years without a bachelor’s degree.
• A completed relevant master’s degree may substitute for one year of experience; a relevant doctorate may substitute for two years.

Additional experience we’d welcome

A master’s degree in an IT‑related subject and at least three years working on enterprise projects or programmes are preferred. Experience in any of the following would also be useful:

• B2B integration, EDI/RosettaNet, partner onboarding, managed file transfer or migration from established integration platforms.
• Java/Spring Boot, stream processing or enterprise messaging.
• Reusable integration templates, self‑service platforms, developer portals or AI‑enabled integration and operational tools.

Relevant Boomi, AWS, Kubernetes or Confluent certifications are welcome. Expertise across every additional technology is not expected.
