Senior AWS Engineer (Graph / Cloud) w/ Top Secret Clearance

About the role

SBS is hiring software engineers who specialize in graph technologies to join our AWS Professional Services team. You will design and build cloud-native applications backed by graph databases — Amazon Neptune, Neo4j, JanusGraph — to model and reason over complex relationships in mission-focused data sets.

You will work shoulder-to-shoulder with AWS architects and customer stakeholders to translate analytic and operational requirements into scalable graph schemas, performant queries, and well-instrumented production services.

Key responsibilities

• Design and build applications backed by graph databases (Amazon Neptune, Neo4j, JanusGraph) for relationship-rich mission data.
• Model complex entities and relationships; tune graph schemas and indexes for query performance.
• Develop and integrate APIs and microservices that expose graph-backed data to consumers.
• Deploy and operate graph workloads in AWS, including capacity sizing, backup/restore, and DR strategy.
• Translate analytic and operational requirements into scalable, maintainable solutions.
• Build data ingestion, transformation, and integration pipelines that feed the graph platform.
• Contribute to CI/CD pipelines, automated testing, and Infrastructure-as-Code for the graph services.
• Diagnose and resolve performance issues across query, storage, and network layers.
• Participate in Agile ceremonies, peer code reviews, and architecture design sessions.

Required qualifications

• U.S. Citizenship. Active Top Secret clearance preferred; candidates in a documented, government-sponsored Top Secret clearance process may be considered where contract and customer requirements permit.
• Five (5) or more years of professional software engineering experience.
• Demonstrated experience developing applications on graph databases (Neptune, Neo4j, or comparable).
• Proficiency in at least one of Python, Java, or JavaScript / TypeScript.
• Hands-on AWS experience with EC2, S3, Lambda, VPC, and IAM.
• Working knowledge of at least one graph query language: Gremlin, SPARQL, or openCypher.
• Demonstrated data-modeling expertise for complex, evolving domains.
• Bachelor's degree in Computer Science, Engineering, or a related field — or equivalent professional experience.
• Clear written and verbal communication skills for technical documentation, stakeholder coordination, and customer-facing delivery.

Prior qualifications

• Prior federal or defense-customer delivery experience.
• Production-scale Amazon Neptune experience (clusters, replicas, bulk loader, streams).
• Experience with data pipelines / ingestion frameworks (Kafka, Kinesis, Glue, Airflow).
• DevOps proficiency: CI/CD pipelines, Infrastructure-as-Code (Terraform, CDK, CloudFormation).
• Containerization with Docker and orchestration with ECS, EKS, or Kubernetes.
• Multi-project consulting or professional-services delivery experience.

Certifications

• Required: None mandatory.
• Preferred:
  • AWS Certified Solutions Architect — Associate or Professional
  • AWS Certified Developer — Associate
  • AWS Certified Data Engineer — Associate
  • Neo4j Certified Professional
