About this role

Principal Software Engineer - Developer, Phantom Works

Company: The Boeing Company

The Boeing Company is currently seeking a Principal Software Engineer / Developer (Level 5) to support our Phantom Works Software Engineering team located in Berkeley, MO (St. Louis area). This position will focus on supporting the Boeing Defense, Space & Security (BDS) business organization. 

You will be part of the Phantom Works Open Architecture Systems Integrated Software (OASIS) Solutions team, where you will define, develop, and lead software development for real-time air and/or space systems in an Agile environment. This role requires close collaboration across teams to integrate software and hardware components, supporting mission-critical Defense infrastructure. Due to the scope and responsibilities of Phantom Works, this position requires a  U.S. Top Secret security clearance for which the US Government requires US Citizenship.

Join Us. Build the Future.

You’ll have the opportunity to make a meaningful impact early in the software development lifecycle while working alongside exceptional Boeing engineers in a collaborative, inclusive team environment.

This position is expected to be 100% onsite.   The selected candidate will be required to work onsite at one of the listed location options. (Berkeley, MO / St. Louis, MO area)

Position Responsibilities: • Own and maintain the software architecture with focus on interface clarity, stability, and versioning to minimize integration risk, with a focus on production type software that is easily maintainable.

• Partner with appropriate stakeholders to inform system definition and oversee translation of system-level requirements into software requirements and models that meet customer, operational and performance requirements and have clear traceability to design, code and test artifacts.

• Manage supplier/subcontractor software deliverables to ensure they meet team processes and integration requirements.

• Lead the software engineering team’s agile delivery: facilitate sprint planning, daily stand-ups, sprint reviews/retrospectives, and remove impediments to flow.

• Serve as the Agile/Delivery lead for software—own backlog prioritization with product/system owners, define sprint goals, and ensure timely delivery of integration-ready increments.

• Define, document, and enforce software integration contracts (ICDs or equivalent living artifacts), data models, and message definitions in coordination with Integration & Test and Systems leads.

• Ensure software is designed for testability: require unit, component, integration, SIL/HIL test artifacts with code deliveries, include observability hooks, and ensure failures are diagnosable.

• Lead DevSecOps and CI/CD practices for the team: ensure pipelines support repeatable builds, automated testing, artifact traceability, and consistent deployments across dev, integration, and test environments.

• Collaborate with Integration & Test to align delivery cadence to integration increments and controlled configuration baselines.

• Drive verification & validation execution for software components: support development of test strategies, analyze test results, and triage defects with the team.

• Establish and track delivery metrics (velocity, cycle time, quality metrics, technical debt) and use them to improve predictability and quality.

• Coach and mentor engineers on agile practices, test automation, CI/CD, code quality, and observability.

• Contribute to risk and issue management that affects software delivery and integration readiness; escalate when necessary to protect integration milestones.

• Document integration results, test findings, and provide inputs for design reviews and readiness assessments.

Basic Qualifications (Required Skills/ Experience): • Bachelor’s Degree

• Active Top Secret U.S. Security Clearance for which the US Government requires US Citizenship. (A U.S. Security Clearance that has been active in the past 24 months is considered active.)

• Advanced degree (MS/PhD) in a relevant field.

• Practical experience with requirements tracing and configuration management.

• Certified Scrum Master (CSM), Professional Scrum Master (PSM), SAFe Agilist, or equivalent agile certification.

• Prior leadership on aerospace, defense, avionics, or other safety‑critical systems.

• Experience with cloud-native infrastructures (Docker/Kubernetes, AWS GovCloud, Azure Government).

• Experience with model-based design/verification and SIL/HIL testing environments.

• Experience managing subcontractor software deliveries.

• Significant experience with real-time embedded software (C/C++), low-level driver development, network stacks, and hardware/software testing/debugging for microcontrollers and/or FPGAs
