Junior Document Controller Jobs in Indiana (NOW HIRING)

Applied Technology Solutions, Inc. (ATS) is seeking a Senior Systems Engineer to lead systems engineering efforts for complex technical projects supporting customer-driven mission requirements. This role is ideal for an experienced engineer who can translate contract requirements into actionable system requirements, drive interface management across multidisciplinary teams, and help ensure technical deliverables are completed with quality, traceability, and compliance.

The Senior Systems Engineer will work directly with customers and collaborate closely with ATS engineers, designers, and program leadership to strengthen systems engineering rigor throughout the design lifecycle. This position will also play a significant role in advancing internal engineering processes, configuration management practices, quality control, and technical review readiness.

The Senior Systems Engineer will provide senior-level technical leadership in requirements development, interface control, milestone planning, deliverable tracking, and engineering execution across a variety of applications. The role supports the full project lifecycle, from early requirements derivation through milestone reviews, verification support, and contract transition-out activities.

This is an engineering-focused systems role, not an IT infrastructure position. The ideal candidate will bring experience in systems engineering for mechanical, aerospace, hardware, or integrated product development environments, preferably within DoD or other highly regulated technical programs.

• Lead the derivation, decomposition, documentation, and traceability of system requirements from Statements of Work (SOWs), contract data requirements, technical direction, and customer expectations.


• Partner with engineering team leads to ensure designs, analyses, and technical deliverables demonstrate compliance with customer, program, and contractual requirements.


• Serve as a primary point of coordination for system interfaces, including development, maintenance, and control of Interface Control Documents (ICDs).


• Drive cross-functional communication among engineering disciplines to resolve interface issues, requirements gaps, and integration risks.


• Support and help lead systems engineering activities associated with technical reviews and contract milestones, including review planning, entrance criteria, exit criteria, action item tracking, and deliverable readiness.


• Track the status of engineering and contract deliverables to support on-time, compliant execution.


• Coordinate with Configuration Management to establish and maintain deliverable indices, drawing trees, bills of materials (BOMs), baselines, and controlled technical data packages as required.


• Support verification planning and evidence collection to confirm that system requirements are satisfied by the final design solution.


• Support project transition-out and closeout efforts by ensuring engineering deliverables are complete, properly controlled, and aligned with customer and contractual expectations.


• Promote systems engineering principles and best practices throughout the product design and development process.


• Contribute to the development, implementation, and continuous improvement of internal engineering processes and procedures related to requirements management, configuration management, quality control, and technical operations.


• Provide technical guidance and mentorship to junior engineers and designers, helping elevate systems thinking across the team.


• Interface directly with customers, internal stakeholders, and program leadership to communicate technical status, risks, integration issues, and path to milestone completion.

• Bachelor of Science in Engineering from an accredited institution.


• 8+ years of relevant engineering experience, with increasing responsibility in systems engineering, technical integration, or product development environments.


• Experience developing, documenting, managing, and tracing system requirements.


• Experience supporting multidisciplinary engineering teams through design reviews, technical milestones, and deliverable execution.


• Experience with interface management, systems documentation, and engineering coordination across functions.


• Secret DoD Clearance, or the ability to obtain and maintain a Secret DoD Clearance.


• U.S. citizenship or other status permitting compliance with applicable export control requirements.

• Bachelor’s degree background in Mechanical Engineering, Aerospace Engineering, or a closely related discipline.


• Experience supporting DoD, aerospace, defense, or other government-funded engineering programs.


• Experience with requirements management and systems engineering tools such as DOORS and/or CAMEO.


• Experience with Model Based Systems Engineering (MBSE).


• Familiarity with configuration management processes, technical baselines, and controlled engineering documentation.


• Experience preparing for and supporting system-level technical reviews and milestone events.


• Strong written and verbal communication skills, with the ability to work effectively with customers and multidisciplinary internal teams.


• Demonstrated ability to lead by influence, organize technical efforts, and improve engineering processes.

• Opportunity to influence system architecture, requirements flowdown, interface definition, and engineering execution on meaningful technical programs.


• High visibility role with direct customer interaction and cross-functional leadership responsibility.


• Chance to help shape and mature systems engineering processes within a growing engineering organization.


• Broad exposure to multidisciplinary design, milestone execution, configuration management, and technical compliance in a defense-focused environment.
