To thrive as a Freelance Full Stack Web Developer, you need strong proficiency in both front-end (e.g., HTML, CSS, JavaScript) and back-end (e.g., Node.js, Python, databases) development, often supported by a relevant degree or portfolio of work. Familiarity with frameworks like React or Angular, version control systems like Git, and cloud platforms such as AWS or Heroku is typically required. Excellent communication, time management, and problem-solving skills help you stand out when working independently with clients. These skills and qualities are crucial for delivering high-quality projects, managing client relationships, and adapting to varied technical requirements.

What are some common challenges freelance full stack web developers face when managing multiple client projects simultaneously?

Freelance full stack web developers often juggle several projects at once, which can make time management and prioritization essential challenges. Balancing deadlines, responding promptly to client communications, and ensuring consistent code quality across different tech stacks require strong organizational skills. Additionally, freelancers must proactively set clear expectations with clients about project scope and turnaround times to avoid scope creep and burnout. Using project management tools and maintaining open communication are key strategies for managing these challenges effectively.

Job description

Why Join Rincon Research Corporation (RRC)?

At Rincon Research Corporation, our primary business is innovating, developing, and fielding digital signal processing (DSP) products and services for the United States Defense and Intelligence Communities in support of national security.

Rincon Research Corporation seeks a Full Stack Developer to create cutting edge software and cloud computing solutions to challenging national security and defense signal processing, geolocation, and communication problems. You will work in a multi-disciplinary R&D environment with similarly skilled and motivated electrical engineers, mathematicians, and computer scientists/engineers in a highly rewarding personal and professional environment.

Come join the team that is creating cutting edge signal processing, geolocation, and communication systems for the future!

What are the primary responsibilities in the Advanced Full Stack Developer position?

Core responsibilities include leading the design and implementation of data systems with both web and database components, analyzing and maintaining existing databases and web interfaces, and adding new features to operational systems. This will include implementing signal processing and other algorithms with efficient software, testing with real data, providing applications to front-line customer facilities, and creating effective user interfaces and data visualization tools. A key responsibility is staying up-to-date with the latest technologies, tools, and methodologies and experimenting with new technologies to incorporate innovative solutions into RRC projects. RRC personnel can expect to work across all functional areas: systems engineering, development, integration and test, deployment and O&M, and experience the direct mission feedback from the customer and seeing your project provide real-world contributions that make a significant difference. You’re encouraged and expected to propose things that you believe will improve the applications and frameworks you’re working in. The ability to work unsupervised with minimal direction and the ability to self-start is a must.

What required background will make you successful?

  • Degree (Bachelor's, Master's, or PhD) in Computer Engineering or Computer Science
  • Minimum 8 years' experience in full-stack application development
  • Experience building scalable web applications using modern frontend and backend technologies
  • Experience designing and consuming RESTful APIs
  • Strong understanding of relational databases and data modeling
  • Proficient in modern software engineering practices for testability and readability
  • Proficient in C++ and Python in LINUX environments
  • JavaScript, CSS, HTML
  • Demonstrated ability to design software systems to ensure they achieve functionality, performance, scalability, and maintainability requirements
  • Ability to obtain and maintain TS/SCI security clearance
  • US CITIZENSHIP REQUIRED

Preferred background:

  • Familiarity with JavaScript frameworks including Vue, React, Angular
  • Advanced SQL query optimization
  • Database performance tuning
  • Stored procedures, indexing, and schema design
  • DevOps and Cloud computing Experience (Gitlab, CI/CD, CVE mitigations, Docker, Kubernetes, PIP)
  • Agile development processes
  • Ability to mentor other engineers and provide technical advice to project leaders
  • Current TS/SCI clearance

Where is the position located?

This position is located at our Centennial, CO office or our Tucson, AZ Headquarters. Remote work/telework is not available for this position.

*The likely salary range for this position is $133,000 to $178,000,000. This is not, however, a guarantee of compensation or salary. Rather, salary will be set based on experience, geographic location and possibly contractual requirements and could fall outside of this range.


What benefits does RRC offer?

  • 100% employer-paid premiums for family medical and dental insurance, employee life insurance, short-term and long-term disability (STD & LTD)
  • Flexible reimbursement spending accounts for medical expense and dependent care
  • Immediate participation and vesting in the company’s Employee Stock Ownership Plan (ESOP) and 401(k) Plan
  • Employer contributions to RRC’s ESOP
  • Employer matching contributions to the company’s 401(k) Plan
  • Employer discretionary contributions to the company’s 401(k) Plan
