Frontend Software Engineer, TS/SCI with Counterintelligence Polygraph Required

Accrete•Alexandria, VA

2d•Onsite

About The Position

Accrete is seeking a Frontend Software Engineer to work at the intersection of data engineering, software development, and AI. This role involves rapidly turning ideas, mission requirements, and technical concepts into working prototypes that can be tested with users and evaluated for production potential. It is a highly hands-on position where you will collaborate directly with engineers, data scientists, AI/ML teams, product managers, and government customers to ingest and manipulate data, build lightweight applications and workflows, test new technical approaches, and iterate quickly based on feedback. The ideal candidate is a strong generalist who enjoys solving ambiguous problems, learning new technologies, and building functional prototypes rather than spending months designing solutions before putting them in front of users.

Requirements

Active TS/SCI clearance with Counterintelligence or Lifestyle Polygraph
3+ years of experience in data engineering, software engineering, application development, or a related technical field
Bachelor's degree in Computer Science, Data Engineering, Software Engineering, or a related technical discipline, or equivalent professional experience
Strong experience with C++, Python, Java, SQL, and any equivalent programming skills
Experience working with APIs and integrating multiple data sources
Experience rapidly developing software prototypes or proof-of-concepts
Strong understanding of software development fundamentals
Ability to work across unfamiliar technologies and quickly learn new tools
Strong problem-solving and debugging skills
Ability to work independently and make technical decisions in an ambiguous environment
Strong written and verbal communication skills

Nice To Haves

Experience supporting the Department of Defense or Intelligence Community
Experience building AI/ML or LLM-powered applications
Experience with RAG, embeddings, vector databases, NLP, or information retrieval
Experience with AI agents and tool-calling workflows
Experience with modern web application development
Experience with FastAPI, Flask, React, or similar frameworks
Experience with PostgreSQL, MongoDB, Elasticsearch, or similar data platforms
Experience with AWS, Azure, or other cloud environments
Experience with Docker and Kubernetes
Experience with Git, CI/CD, and modern software development workflows
Experience with Spark, Airflow, Kafka, Databricks, Snowflake, or similar data technologies
Experience working in classified, secure, or air-gapped environments
Experience taking prototypes into production
Experience developing applications for government or national security customers
Ability to obtain and maintain additional security clearance accesses to Special Access Programs (SAP) or Access Compensatory Control Measures (ACCM)

Responsibilities

Rapidly develop functional software prototypes to demonstrate new concepts and capabilities
Translate ambiguous mission requirements into working technical solutions
Build proof-of-concepts that combine data, APIs, AI models, and software components
Develop lightweight applications, services, scripts, and interfaces to test new ideas
Iterate rapidly based on user feedback and technical findings
Evaluate prototype approaches and make recommendations for production implementation
Work across the technology stack as needed to get prototypes operational
Identify technical risks, limitations, and dependencies early in the development process
Maintain clear documentation of prototype architecture, functionality, and technical decisions
Build data ingestion and transformation pipelines to support prototypes
Integrate structured and unstructured data from multiple sources
Work with APIs, databases, files, feeds, and other data sources
Clean, normalize, transform, and enrich data for analytical and AI applications
Develop SQL queries and Python-based data processing workflows
Monitor data pipelines and troubleshoot data quality and integration issues
Create reusable data workflows that can transition from prototype to production
Integrate AI and machine learning capabilities into software prototypes
Work with LLMs, embeddings, RAG, information retrieval, and AI agents where appropriate
Develop prototypes that automate manual or knowledge-intensive workflows
Experiment with different AI models, APIs, tools, and architectures
Build workflows that combine data processing with AI-driven analysis or decision support
Develop evaluation methods to measure prototype performance and usefulness
Work closely with data scientists and AI engineers to test new approaches
Partner with software engineers, data scientists, product teams, and mission experts to understand requirements and quickly convert them into a minimum viable product for collecting feedback
Participate in technical design sessions and architecture discussions
Translate customer needs into technical requirements and implementation plans
Communicate prototype capabilities, limitations, and technical tradeoffs
Support demonstrations and technical discussions with government customers
Provide recommendations on whether and how successful prototypes should be productionized
Draft software documentation
Work directly with government customers and mission users to understand operational challenges
Rapidly respond to emerging technical requirements and mission needs
Build prototypes that demonstrate measurable mission value
Support customer demonstrations, testing, experimentation, and deployment
Operate effectively in secure and potentially classified environments
