First Year Software Engineer Internship information

What is a first year software engineer internship?

A First Year Software Engineer Internship is an entry-level position designed for college students in their first year of study who are interested in pursuing a career in software engineering. Interns in this role typically work on real-world projects, learn programming languages, collaborate with experienced engineers, and gain hands-on experience in software development. These internships help students build foundational technical skills, understand the software development lifecycle, and explore potential career paths in technology. They also provide networking opportunities and sometimes lead to future full-time positions.

What kinds of projects does a first year software engineer intern typically work on?

First-year software engineer interns are often assigned to collaborative projects that focus on foundational development tasks such as bug fixes, feature enhancements, or writing unit tests. These projects are designed to help interns become familiar with the company's codebase, development tools, and best practices, while allowing them to make tangible contributions. Interns usually work alongside experienced engineers who provide mentorship and code reviews, creating a supportive environment for learning and growth. This hands-on experience not only improves technical skills but also builds confidence in working within a professional software engineering team.

What are the key skills and qualifications needed to thrive as a first year software engineer intern?

To thrive as a First Year Software Engineer Intern, you need a foundational understanding of programming concepts, problem-solving skills, and coursework or experience in computer science fundamentals. Familiarity with languages like Python, Java, or C++, and knowledge of version control systems such as Git, are typically expected. Strong communication, eagerness to learn, and teamwork help interns adapt quickly and contribute effectively in collaborative environments. These skills and qualities are important because they enable interns to learn efficiently, work productively with teams, and successfully tackle real-world engineering challenges.

What is the difference between First Year Software Engineer Internship vs Software Engineer?

Job description

Position Summary
We are seeking a Mid-Level Software Engineer to contribute to the development of the Multimode Threat Engagement Simulation Platform under the technical direction of the Lead and Senior Staff Engineers. You will build features across the stack - backend physics API endpoints in Julia, React/TypeScript UI components, and Cesium map view integrations - while growing your expertise in high-performance scientific computing and defense mission engineering applications.
This role is an opportunity to develop real depth in an intersection of disciplines that is rarely available at early career: scientific computing with Julia, 3D geospatial visualization with CesiumJS, and the physics of aerospace and defense sensor systems. You do not need to arrive with domain knowledge - you will acquire it through hands-on work alongside domain experts and through structured mentorship from the Lead Engineer. What you do need is a solid programming foundation, genuine curiosity about computational physics, and the ability to write clear, tested, maintainable code.
***Contingent upon contract award***
Responsibilities
Backend Development
  • Implement and test Julia HTTP API endpoints for mission data CRUD operations, trajectory query routing, and physics result serialization
  • Write Julia utility functions for data format conversion: GeoJSON, CZML, mission JSON schema parsing and generation
  • Assist with Monte Carlo driver implementation: input parameter perturbation, result aggregation, and statistical output computation (CEP, R95, Pk distribution)
  • Write unit and integration tests for computation backend endpoints; validate API response schemas against the frontend contract
  • Maintain and extend the mission data serialization layer: add new asset types, task attributes, and output fields while preserving backward compatibility with existing save files

Frontend Development
  • Build and maintain React/TypeScript components for the mission planning UI: forms for asset creation and editing, task assignment dialogs, mission parameter panels, and tabbed navigation
  • Implement Cesium/Resium map features: add new asset marker types, update entity styling based on mission state, and wire up click/hover interactions between the globe and the mission data panel
  • Consume Julia backend API endpoints from the React frontend: implement fetch calls, loading states, error handling, and result rendering for trajectory and analysis queries
  • Write TypeScript type definitions for all mission data structures shared between the frontend and the Julia API

Testing and DevOps Support
  • Write automated tests at the component level (React Testing Library or equivalent) and integration level (API contract tests)
  • Assist with CI/CD pipeline maintenance: diagnose build failures on Windows and Linux targets, update dependency versions, and validate packaged installer behavior
  • Participate in code review: give and receive feedback on correctness, performance, and readability
  • Maintain technical documentation: update API reference docs, build guides, and developer setup instructions as features evolve

***Contingent upon contract award***
Qualifications
Citizenship: Must be a US citizen
Minimum Required Qualifications
Clearance: Active Secret Clearance
Education: B.S. in Computer Science, Software Engineering, Electrical Engineering, Physics, or related STEM field
Years of Experience: 1-4 years of software development experience, including internships, research projects, or personal projects demonstrating relevant technical depth
Certifications: NA
Additional Skills
  • Proficiency in at least one programming language with strong typing discipline (TypeScript, Python, Java, C++, Rust, or Julia)
  • Familiarity with REST API design patterns: HTTP methods, JSON request/response schemas, status codes, and client-side error handling
  • Working knowledge of React or equivalent component-based frontend framework, OR demonstrated experience with scientific computing / numerical methods in Python, MATLAB, Julia, or C++
  • Ability to write readable, tested code and iterate based on code review feedback

Preferred Qualifications
  • Any exposure to Julia, even through coursework, online resources, or personal projects
  • Familiarity with geospatial concepts: coordinate systems (WGS84, ECEF, ENU), map projections, or GIS tooling
  • Experience with a scientific computing environment: MATLAB, NumPy/SciPy, or equivalent
  • Curiosity about aerospace, defense, or mission engineering applications - you don't need to know the domain, but you should want to learn it
  • Experience with Electron desktop application development

Additional Information
Location: Colorado Springs, CO or Boston, MA
Travel: Approx. 15-20%
Remote, Onsite, or Hybrid: Hybrid
