Internship Software Engineering information

What skills and qualifications are needed to thrive as an internship software engineer?

To thrive as an Internship Software Engineer, you need a solid understanding of programming fundamentals, problem-solving abilities, and coursework or experience in computer science or related fields. Familiarity with coding languages like Python, Java, or C++, and experience using version control systems such as Git are typically expected. Strong communication, a willingness to learn, and teamwork skills help you adapt to new environments and collaborate effectively. These skills and qualities are crucial for quickly contributing to projects, learning from mentors, and succeeding in a dynamic tech setting.

Employer & Industry UsageUsed by tech companies, startups, and educational institutions for trainingUsed across industries for building and maintaining software products
Common Search & Comparison IntentUnderstanding entry points and learning opportunities in software engineeringSeeking career progression or job opportunities in software development

Internship Software Engineering positions are designed for students or recent graduates to gain practical experience, often with a focus on learning and skill development. Software Developers are full-time professionals responsible for creating, testing, and maintaining software applications. The internship is temporary and educational, while the developer role is a long-term career position.

What types of projects do software engineering interns typically work on, and how much ownership do they have over their tasks?

Software Engineering Interns often contribute to real-world projects that align with the team's current goals, such as building new features, fixing bugs, or improving existing systems. Interns are usually given a defined scope of work and are encouraged to take ownership of their assigned tasks, while still receiving guidance and mentorship from full-time engineers. This balance provides valuable hands-on experience, exposure to industry-standard tools and workflows, and an opportunity to make meaningful contributions while learning in a supportive environment.

What is an internship software engineer?

Internship software engineers are students or recent graduates who work temporarily at a company to gain practical experience in software engineering. They assist with coding, debugging, testing, and collaborating with professional engineers on real-world projects. These internships help participants develop technical skills, understand workplace dynamics, and build their professional network, often serving as a pathway to full-time employment.

Internship

Re-posted 12 days ago


Job description

About Instead
Instead is where tax work gets done. Our AI agent orchestrates the entirety of how work gets done in tax, from preparation and compliance to filing and advisory. It's a fundamentally new way of doing tax work, and it's why top 500 firms, Big Four teams, and enterprise corporate tax departments are choosing Instead.
What makes us unique: we hold full government approvals with the IRS, 48 states, and all cities to e-file 1040, 1041, 1120, 1120S, and 1065, with 706, 709, 990, 5500, 2290, and PPT coming for tax year 2026. Instead is a full replacement for CCH Axcess, GoSystem, UltraTax, OneSource, CorpTax, Lacerte, ProConnect, Drake, and more. No other tax startup will be able to offer these capabilities for years as we are two to three years ahead of everyone else in government approvals. This lets us build product experiences that are simply unmatched in the market.
Instead is backed by Conviction, IRIS (the largest tax software provider in the UK), Skylark, Aprio, and many of our partners and customers. Our team includes leaders from Intuit, Gusto, Zenefits, Thomson Reuters, Wolters Kluwer, PwC, BDO, RSM, and KPMG.
The Role
We're looking for Software Engineering Interns to join our San Francisco team and build real features on our AI-powered tax platform. This is not a coffee-fetching internship. You'll ship production code that hundreds of accounting firms use, work alongside senior engineers, and get hands-on experience building with AI tools from day one.
Our stack: Vue, Nuxt, TypeScript, and Tailwind CSS on the frontend. Go, Docker on AWS ECS/Fargate, and PostgreSQL on AWS RDS on the backend. For AI, we use Cursor, Claude Code, Helicone, Gemini, and OpenAI, and we're constantly evaluating new tools.
What You'll Do
  • Ship product features end to end on our live customer platform alongside senior engineers
  • Build and test AI-powered components including inference pipelines and prompt engineering
  • Fix bugs and make product improvements based on real customer feedback
  • Create internal tools that make the engineering team more productive
  • Learn our full stack and contribute across frontend, backend, and AI layers
  • Participate in code reviews, architecture discussions, and product planning
What You Bring
  • Currently pursuing or recently completed a degree in Computer Science, Software Engineering, or a related field
  • Strong programming fundamentals. You can write clean code, debug efficiently, and think about edge cases
  • Familiarity with web development (frontend or backend). Experience with any modern framework counts
  • Curiosity about AI and willingness to learn. Experience with AI coding tools (Cursor, Claude Code, GitHub Copilot) is a plus
  • High attention to detail and a bias for shipping
  • Ability to work on-site in San Francisco
What Makes Someone Exceptional
  • You've built and shipped side projects or open-source contributions that demonstrate your ability to go from idea to working product
  • You already use AI tools in your coding workflow and understand how they change the way software gets built
  • You learn fast and don't wait to be told what to do. When you see something broken, you fix it
  • You care about the end user, not just the code. You want to understand why something matters before you build it
  • You're excited about working at a startup where your work ships to real customers on day one
Location
San Francisco (on-site)
Instead is an equal opportunity employer. We evaluate candidates based on capability, judgment, ownership, and fit for the role's responsibilities. We welcome candidates who can help us build a category-defining company in tax technology.
