About the role

This is a leadership role shaping the future of Mimecast's Incydr product line.
It detects when sensitive data moves in risky ways across endpoints, cloud apps, email, and removable media, prioritizes the activity that actually matters, and gives security teams the context to investigate and respond before data walks out the door.

Shape problems with product partners: Contribute at the problem-framing stage, not just after requirements land.
Own integration contracts as product artifacts: Help define how the product line touches the rest of the Mimecast platform.
You'll own the durable interfaces - APIs, events, and data contracts.
Build the architectural context engineering teams operate inside: ADRs, data contracts, and service interaction patterns.
Drop into detailed technical design when the problem warrants it or when you're unblocking a team - and know when to step back out.
Propose technical debt work: Identify and prioritize debt reduction with Product Management partners.
Architecture experience at scale: 8+ years building and operating production systems, and engaging with product early in the cycle.
Time as a Solutions Architect, Principal Engineer, Tech Lead, Product Architect, Staff Engineer, or equivalent.

Strong working knowledge of AWS (ECS/EKS, S3, DynamoDB, SQS/SNS, IAM, VPC), Kafka, and the ability to reason about distributed systems at high volume.

Senior Solutions Architect - Insider Risk (Incydr)
Why Join Us?
The interesting work in enterprise security has moved inside the organization.
AI agents are creating new insider risk and compliance obligations every day.
Data is sprawling faster than the controls around it.
At Mimecast, our product lines sit where all of that converges.
AI-First Architecture at Mimecast
Mimecast is an AI-First engineering organization.
Comfort designing with - and for - LLMs, agents, and modern AI architectures is core to this job, not a side interest.
Incydr is our insider risk management and data protection platform.

For AI features, extend that to eval coverage, agent boundary safety, and prompt/data-contract stability.

These are how architecture decisions get propagated and enforced at scale across humans and agents - they're part of the build system, not the wiki.
