Expect a process that prioritizes open discussion around your prior technical projects, software design philosophy, and specific language skills.

The overall timeline moves swiftly once your security clearance is confirmed. The company places high value on establishing a strong mutual fit, ensuring you are matched with a subcontract or internal project team aligned with your career goals and technical interests.

The visual timeline above outlines the standard progression from initial candidate outreach to formal offer integration. Candidates should use this workflow to map out their technical review, ensuring key domain competencies are refreshed prior to the technical interview stage. Depending on project specificities and clearance verification timelines, certain steps may proceed concurrently.

To excel during technical assessments, candidates must understand the specific engineering domains prioritized by Gliacell Technologies. Depending on your targeted sub-specialty—such as Data Science/ML, Full-Stack, Cyber Operations, or Systems Engineering—you will face scenario-based evaluations tailored to these core areas.

Advanced Python, Machine Learning & Analytics

This area evaluates your practical capacity to construct processing analytics, design feature pipelines, and operationalize Machine Learning models for complex data sets.

Interviewers assess how well you manipulate data using Python, extract meaningful indicators, and build scalable automated analytical tools.

Be ready to go over:

As a Software Engineer at Gliacell Technologies, your day-to-day responsibilities combine software creation, system maintenance, and technical consultation in support of national security clients. You will work within small, focused Agile development pods alongside systems engineers, data scientists, and mission subject matter experts.

A central responsibility involves designing, enhancing, and prototyping software tools for enterprise processing, business analytics, and mission compliance. You will regularly write clean, tested code in languages like Python, Java, Scala, or C++, operating predominantly inside Linux environments. Depending on your team assignment, you may build real-time data flows, deploy machine learning models using Scikit-learn, or construct automated test automation suites utilizing Robot Framework.

Beyond core software development, you will participate actively in technical design reviews, software trade-off analyses, and system integration testing. Engineers regularly evaluate Commercial Off-the-Shelf (COTS) and Government Off-the-Shelf (GOTS) solutions to make informed build-versus-buy recommendations. Documentation is an integral part of the delivery process; you will maintain project wikis, API specifications, and workflow charts in Confluence and track sprint execution through Jira.

Candidates applying for the Software Engineer position at Gliacell Technologies must meet clear security clearance, educational, and technical baseline requirements. Because roles range from mid-level to principal engineering levels, requirements scale proportionally with seniority.

Must-Have Qualifications

• Security Clearance – Active or reinstatable TS/SCI clearance with Polygraph (U.S. Citizenship mandatory).
• Core Engineering Experience – Minimum of 7 years of professional experience (or 4 years plus a Bachelor’s degree in Computer Science/Engineering) for Mid-Level roles; 14+ years of experience for Senior/Principal roles.
• Primary Languages – Demonstrated proficiency in Python, Java, C++, or Scala.
• Operating Environment – Solid hands-on development experience in Linux environments.
• Development Tools – Practical experience with version control (Git, GitLab, or Bitbucket) and issue management software (Jira, Confluence).

Nice-to-Have Qualifications

• AI & Data Science – Experience with Scikit-learn, Random Forest, Jupyter Notebooks, Spark, LLMs, or Agentic AI framework implementations.
• Cloud & DevOps – AWS Solutions Architect or AWS ML certifications, experience with Docker, Kubernetes, and cloud infrastructure management.
• Search & Query Tools – Hands-on experience with Lucene, Elasticsearch, JEXL, SQL, and JSON parsing.
• Testing & UI Frameworks – Proficiency in UI test automation using Robot Framework alongside modern frontend libraries like React.
• Cyber Domain Expertise – Prior experience in CNO/CNE/CND development, reverse engineering, or threat hunting solutions.

Q: What security clearance is required for this role? An active or reinstatable TS/SCI with Polygraph is strictly required for nearly all software engineering positions across Gliacell Technologies project locations. Candidates without an active clearance at this level cannot be considered.

Q: Are remote or hybrid work options available? While many core intelligence subcontracts require full-time onsite presence at customer facilities (such as Laurel, MD, or Annapolis Junction, MD), select senior and principal roles offer partial telework or flexible schedule arrangements depending on project security guidelines.
