They are typically hired on a contractual basis to complete specific projects or provide specialized expertise for a set duration. Independent contractors manage their own schedules, handle multiple clients, and are responsible for their own taxes and business expenses. This arrangement offers flexibility but also requires strong self-management, business skills, and a clear understanding of project requirements.

Proactively addressing questions, setting realistic deadlines, and documenting progress help prevent misunderstandings and foster strong client relationships, which can lead to repeat business and referrals.

What are the key skills and qualifications needed to thrive as an independent contractor software developer, and why are they important?

To thrive as an Independent Contractor Software Developer, you need strong programming skills, a solid understanding of software development principles, and relevant experience or a degree in computer science or a related field. Familiarity with version control systems like Git, cloud platforms, and proficiency in popular programming languages, along with certifications such as AWS Certified Developer or Microsoft Certified: Azure Developer Associate, are often beneficial. Excellent communication, time management, and problem-solving abilities set standout contractors apart, enabling effective client interaction and project delivery. These skills and qualities are crucial for producing high-quality software, meeting client expectations, and managing projects independently.

Job description

Sonalysts, Inc. is seeking an experienced systems engineer to provide engineering support to a DoD weapon acquisition program. The successful candidate will manage Systems Engineering Technical Reviews throughout the acquisition cycle, keep multi-disciplinary teams aligned, accelerate decision-making, and directly impact the success of mission-critical systems. As part of the technical backbone of a diverse project team, the successful candidate will help guide requirements, steer risk, and ensure flawless delivery from concept through fleet fielding.

 

Who are we?

Sonalysts, Inc. is a small, 100% employee-owned business (ESOP) that supports a very diverse set of customers. While the company was originally founded in 1973 with a focus on sonar analysis for the Navy (hence the name), Sonalysts has since expanded into a variety of other Defense and Commercial spaces. With current contracts supporting the Navy, Air Force, Army, and many other customers, Sonalysts leverages the skills and knowledge of its employee owners to help solve the Department of Defense's most challenging problems while providing the best benefit to our customers. Sonalysts has a diverse and capable workforce comprised of former and retired service members from all branches of the military, and professionals with a wide range of commercial and technical backgrounds. From software development to operations analysis, doctrinal development, engineering, wargaming, targeted knowledge elicitation, or large group facilitation, Sonalysts can meet any challenge.

A small, central corporate structure coupled with a largely de-centralized approach to project management enables Sonalysts to compete with larger Defense Contractors in providing rapid, innovative solutions to meet customer needs while remaining agile and entrepreneurial at heart. Our employee-owners lead and support existing projects while also developing new business and winning new work.

If you are looking to use your technical or operational knowledge to solve challenging problems for the military while benefiting from the flexibility and empowerment of being a contractor or potential future leader in a small business, then Sonalysts may be the place for you.

What you will be doing: 

  • Facilitate working groups, integrated product teams, and program review meetings.
  • Communicate technical information clearly to government, contractor, and internal stakeholders.
  • Manage action item tracking, risk mitigation, and schedule integrity throughout the acquisition lifecycle.
  • Translate complex technical data into clear, actionable insights for leadership.
  • Participate in all areas of program development by partnering with experts in mechanics, software, test, and certification to tackle the toughest engineering challenges.
  • Contribute to requirements management, testing, qualification, certification, and fielding to the fleet.
  • Implement Model-Based Systems Engineering (MBSE) practices and maintain system models
  • Work primarily on-site at Sonalysts' headquarters or designated government facilities to stay closely aligned with project teams.

Required Qualifications:

Strongly Desired Experience/Qualifications:

  • Experience with model-based systems engineering
  • Experience providing systems engineering support to a DoD acquisition program 
  • Ability to lead cross-functional teams and resolve complex technical issues
  • Strong analytical, problemsolving, and communication skills

What's in it for you?

  • Opportunity to provide important support to the DoD and to expand your work portfolio to support various projects across the company.
  • Opportunity to grow your skillset and pursue project leadership.
  • Salary ranges between $90,000-$130,000, dependent on experience, qualifications and other relevant business criteria.  
  • Becoming an integral part of an innovative employee-owned company which includes:
    • Flexible Time Program enabling an optimal work-life balance by permitting partners to arrange their work around personal appointments and vacations, parent-teacher conferences, children's activities and the like, so long as the partner gets the job done on time.
    • Paid Time Off
    • 401(k) Plan with company match
    • Employee Stock Ownership Plan (ESOP)
    • Sales Bonus Program
    • Special Performance and Retention Bonus Program
    • Health and Dental Insurance
