About Our Client & The Engagement
Our client is a premier AI consulting group that builds serious, production-grade systems for companies ready to operationalize artificial intelligence across their business. They eschew gimmicks and prototypes, focusing instead on delivering custom AI that integrates seamlessly into operations to drive measurable results. Their work automates high-effort workflows, launches AI-powered product lines, and transforms internal data into structured, usable assets—ranging from custom-trained models to intelligent agents that reason across complex business logic. Their diverse clientele spans education, financial services, engineering, healthcare, and defense. This is an 8-month full-time engagement with the potential to become a permanent position
The Project
We are hiring several senior backend engineers across the build. The components differ in domain (data integration, audience segmentation, access and authorization, and communications), but the engineering profile is the same: senior Java engineers who design and operate large-scale, event-driven, distributed systems on a cloud-native stack. Placement onto a specific component is matched to your background. You won't be slotted into a feature factory: you'll drive architecture alongside the team and own services end to end.
Responsibilities
Design, build, and evolve core platform services, data models, and APIs
Build reliable, replayable, event-driven data and processing pipelines at scale
Drive architectural decisions on scalability, resiliency, security, and operability
Design delivery mechanisms and integrations for downstream consumers
Implement data governance, lineage, auditability, and regulatory compliance
Support multi-tenant isolation and regional data residency
Partner with product and engineering to define platform capabilities and roadmap
Support customer migrations from legacy systems into the new platform
Mentor engineers and contribute to technical leadership across the team
Ensure reliability, performance, observability, and operational excellence
Required Experience
5+ years as a backend or platform engineer (software developer or data engineer)
Strong expertise in Java
Experience building distributed systems at scale
Strong experience with event-driven architectures
Hands-on with stream processing or messaging systems (Apache Beam, Spark, Flink,Kafka, or queues/streams/brokers)
Strong data modeling and schema design skills
Experience designing scalable APIs and backend services
Cloud-native architecture experience (GCP preferred)
Experience designing multi-tenant SaaS platforms
Strong understanding of system reliability, fault tolerance, and observability
Proven ability to drive architectural decisions and technical initiatives
Strong communication and collaboration skills
Advanced English level
Bonus
Scala
Apache Beam/Dataflow in production, and Cloud Spanner
Data platforms, MDM, CDP, or identity resolution systems
Query engines, search platforms (Elasticsearch, OpenSearch), rules engines, orsegmentation platforms
Graph-based data models and relationship traversal
Authorization systems (RBAC/ABAC), IAM, policy engines (OPA), API gateways, or service mesh
Security-critical, compliance-heavy, or regulated environments, and data governance/audit systems
Email/SMS delivery, telecom or messaging infrastructure, notification, or marketing automation systems
Workflow engines and high-throughput event processing
Migrating large-scale legacy systems to cloud-native architectures
EdTech or enterprise integration domains
