Job description

About the Team
Here at BTI360, we've built a culture that's passionate about developing software engineers. Software doesn't build itself. People do. In fact, teams of people do. That's why our primary focus is on developing better craftsmen, better teammates, and better technical leaders. By putting people first, we're not just giving our teammates more opportunities to grow, we're also raising the bar of the software we ship. BTI360 previously has been voted 10 years in a row as a TOP Place to Work by the Washington Business Journal.
BTI360 is seeking an Knowledge Graph Software Engineer who is passionate about transforming raw data into meaningful insights that drive strategic decision-making. In this role, you'll work closely with our engineers and mission teams to tackle complex business problems using emerging AI technologies - specifically by extracting and linking critical entities to build and curate scalable graph databases and knowledge bases. This role sits at the intersection of backend software engineering, knowledge representation, and applied AI.
What you will do in this role:
As a Knowledge Graph Software Engineer at BTI360, you will:
  • Lead end-to-end knowledge graph and knowledge base development efforts from problem definition to production, designing pipelines that extract, normalize, link, and organize information into scalable graph-based systems.
  • Design and evaluate extraction and resolution workflows using sound methodologies and fit-for-purpose metrics to assess entity extraction, linking, relationship quality, and overall knowledge base completeness and accuracy.
  • Translate business requirements into quantitative problems and communicate technical findings to both technical and non-technical stakeholders through reports, presentations, and direct customer engagement.
  • Drive technical decision-making for schema design, ontology alignment, extraction approaches, and graph architecture based on mission needs, data quality, and long-term maintainability.
  • Stay current with advances in knowledge representation and information extraction and introduce practical techniques, tools, and frameworks that improve graph construction, curation, and analytic value.
  • Apply analytical and statistical methods to validate extracted insights, measure data quality, and support confident decision-making from structured and unstructured sources.
  • Develop reports and whitepapers that evaluate solution alternatives based on impact, cost, technical feasibility, and alignment with strategic goals.
  • Collaborate across teams to align on strategy, provide data science expertise, and contribute to proposals and strategic initiatives.
  • Mentor junior data scientists by providing technical guidance, defining project direction, and sharing best practices in graph-oriented data modeling, extraction workflows, and knowledge base stewardship.

The ideal candidate should possess the following skills:
  • Active Security Clearance (Secret or higher) or the ability to obtain one
  • Hands-on experience with graph databases such as Amazon Neptune, Neo4j, or related graph technologies.
  • Experience with source control (e.g. Git) and CI/CD pipeline tools such as AWS CodeBuild (preferred), Jenkins, GitLab CI, or GitHub Actions
  • Experience designing and implementing scalable, maintainable, and OOP based software in a containerized cloud environment (AWS preferred) leveraging foundational services for computing, identity management, and networking.
  • Experience developing backend services using Java and the Spring/Spring Boot framework (or similar relevant Java framework)
  • Experience with testing frameworks such as Junit (preferred), Mockito, or Spring Runner
  • Familiarity with API standards such as REST and HTTP, message-driven architectures, persistent storage layers, and distributed systems
  • Effective written and verbal communication skills necessary to perform job duties and collaborate with team members
  • Candidates must maintain a primary residence within a two hour drive of Herndon, VA to support onsite collaboration as needed.

Desired skills:
  • Familiarity with monitoring and observability stacks such as PrometheGrafana (preferred), CloudWatch, or ELK/EFK
  • Contributions to open-source libraries or community projects or personal projects
  • Experience with search technologies such as OpenSearch (preferred), Elasticsearch, or Solr
  • Experience working with streaming or event-driven architectures such as SNS/SQS (preferred), Kafka, Kinesis, AWS Step Functions, or Event Bridge
  • Knowledge of Infrastructure as Code (e.g., Terraform) and how to leverage DevSecOps pipelines to deliver code
  • Exposure to additional programming languages including shell scripting languages (e.g. Python, NodeJS, C#, Bash, PowerShell)
  • Exposure to modern AI-assisted software development workflows, including agentic development frameworks and LLM tooling
  • Familiarity with monitoring and observability stacks including OpenTelemetry, Splunk (preferred), PrometheGrafana, or CloudWatch

The base salary pay range for this role is $125,900 - $247,900. This range reflects base compensation only and does not include benefits, bonuses, or additional pay incentives associated with the opportunity.
BTI360 benefits for full-time teammates
  • Fully paid healthcare premiums
  • Competitive salaries and performance bonuses
  • Career development and in-house training
  • Tuition Reimbursement
  • Up to 5 weeks PTO plus 2 weeks of federal holidays
  • 401K dollar for dollar matching up to 6% annually - vested immediately on day 1
  • Giving Back: Serving communities locally and across the globe
  • Social Events (happy hours, golf tournament, BTI360 Family Festival and more)

Commitment to Fairness and Inclusion
