What is an OPT internship?

An OPT (Optional Practical Training) Internship is a temporary work opportunity for international students in the U.S. on an F-1 visa. It allows students to gain practical experience in their field of study during or after completing their academic program. OPT internships can be paid or unpaid and must be related to the student's major. Students typically apply for OPT authorization through USCIS, and they can work for up to 12 months (or 24 months for STEM fields with an extension).

What type of projects or tasks can I expect to work on during an OPT internship?

OPT Interns typically gain hands-on experience by assisting with real-world projects relevant to their field of study, such as data analysis, research support, software development, or design tasks. You may be assigned to collaborative teams, receive mentorship from senior staff, and be expected to present your findings or progress in meetings. The projects are designed to develop both your technical skills and understanding of industry practices, helping you build a professional portfolio. Engaging with meaningful work and cross-functional teams will provide valuable insights and prepare you for future full-time opportunities.

What are the key skills and qualifications needed to thrive in the OPT internship position, and why are they important?

To thrive as an OPT Internship candidate, you should possess a foundational understanding of your field of study, strong analytical abilities, and be enrolled in or recently graduated from a U.S.-accredited college or university. Familiarity with relevant industry software, technical tools, or laboratory equipment specific to your discipline is often required. Excellent communication, adaptability, and a proactive learning attitude are valuable soft skills in this role. These skills ensure you can contribute effectively, maximize your learning, and successfully transition into a professional career environment.

Software Engineering Internship

Hypercubic, Inc

San Francisco, CA • On-site

Full-time

Posted 6 days ago

Job description

The world's most critical infrastructure-banking, airlines, utilities-is held together by millions of lines of COBOL and mainframe logic written decades ago. The engineers who built it are retiring and the documentation is fading. These systems are "too big to fail" and "too complex to change," leaving global infrastructure frozen in the 1970s.
At Hypercubic, we're building AI systems that can understand, reason about, and rearchitect large-scale legacy applications. We work at the intersection of program analysis, knowledge extraction, and agentic systems, applied to some of the most critical enterprise software in the world.
Learn why we're excited about mainframe modernization.
About the Role
We are looking for students with unusually high slope and strong engineering taste. You will work directly with the CTO to design, prototype, and productionize AI-powered systems from first principles.
You'll start by owning a well-scoped project that ships to production. As you demonstrate strong judgment and execution, you'll take on broader ownership. Interns who perform well may receive an offer to join Hypercubic full-time.
This role is suited for someone with strong fundamentals who learns quickly and is comfortable working across abstraction layers, from low-level system reasoning to high-level product interactions.
What You'll Do
  • Own and ship a high-impact engineering project end to end.
  • Rapidly prototype new concepts and features to validate ideas before full implementation.
  • Build AI-driven systems, including agent workflows, evaluations, program-analysis tooling, backend infrastructure, and user-facing features.
  • Translate ambiguous problems into concrete experiments, constraints, and working systems.
  • Contribute to engineering standards around testing, reliability, and code quality.
  • Work directly with the CTO on technical and product decisions, taking on greater ownership as you earn trust.
  • Collaborate with subject-matter experts and customers across industries including banking, insurance, airlines, and utilities.

You are a Fit if...
  • You care deeply about your work and the product you are building.
  • You have strong programming fundamentals and can learn unfamiliar tools and systems quickly.
  • You have demonstrated your abilities through ambitious projects, research, open-source contributions, internships, or exceptional coursework.
  • You are comfortable with uncertainty and enjoy figuring out what to build before determining how to build it.
  • You think in systems and feedback loops, not just features.
  • You can move fast and slow-prototyping ideas in hours, then developing the most promising ones to a high-quality bar.
  • You can reason clearly about technical decisions and communicate your thinking.
  • You want to become world-class at AI engineering.
  • You have a bias for action and thrive in fast-moving environments.
Nice to Have
  • Experience building complex agentic products, infrastructure, or autonomous systems.
  • Strong testing intuition, including experience with TDD or property-based testing.
  • Experience building and maintaining production-grade software.
  • Exposure to legacy systems (especially mainframes or COBOL), compilers, program analysis techniques, or high-performance computing (HPC).
  • Familiarity with enterprise software constraints.
Logistics
  • Eligibility: Open to currently enrolled undergraduate and graduate students of any year, degree program, or major.
  • Location: This is a full-time, in-person role based in San Francisco, California.
  • Timing: Start dates are flexible and applications are considered on a rolling basis. We can accommodate summer internships, semester-long internships, and co-op schedules.
  • Relocation: Relocation support is available as needed.
  • Work authorization: Candidates must already be authorized to work in the United States. We can support CPT and OPT, but cannot sponsor new visas.
