Software Engineer Intern

You will report directly to our CTO David, which is an amazing opportunity to learn fast and grow.

As a Software Engineer Intern at TwoWay, you’ll be part of a fast-moving team building critical tools for investment bank traders. This is not a typical internship — you’ll work on real features, contribute to core product decisions, and ship code that goes into production.

You’ll collaborate closely with senior engineers, product designers, and the founders. From day one, you’ll be trusted with meaningful responsibility and given the support to learn and grow quickly.

As a key member of the team, you’ll do the following missions:

• Build and improve core features of our web application, from backend logic to frontend UI


• Contribute to the design and architecture of new components and APIs


• Collaborate with the product team to understand user needs and translate them into clean, maintainable code


• Write tests and participate in code reviews to maintain high code quality


• Investigate and fix bugs in a fast-paced production environment


• Learn best practices in software development, DevOps, and product iteration in a startup setting

You’d be a great fit if you

• Build Fullstack Products: You’re comfortable working across the stack — with experience or strong interest in modern frameworks like SvelteKit on the frontend and NestJS or Node.js on the backend. You love shipping features end-to-end.


• Thrive in Fast-Paced Environments: You’re energized by startups. You enjoy learning quickly, taking initiative, and iterating fast in a dynamic, high-growth setting.


• Care About UX and Details: You pay attention to UI/UX consistency, performance, and believe the best software feels as good as it works.


• Think Long-Term: You understand the importance of clean code, maintainability, and security, even when moving fast.


• Stay Curious and Data-Informed: You ask questions, seek feedback, and back decisions with evidence. You’re not afraid to challenge assumptions and improve how things are done.


• Are a Strong Communicator: You explain technical ideas clearly, ask for help when needed, and enjoy collaborating with product and design peers.

We keep our process fast, clear, and respectful of your time. Here’s what to expect:

1. Intro call – A 30-minute conversation to get to know each other and align on expectations


2. Case study – A practical exercise to understand how you think and work


3. Founder interview – A deeper discussion with one of our cofounders to assess mutual fit and ambition


4. Offer – If it’s a match, we move fast to get you on board

You’ll get transparent communication at every step. We want this to be as much about you evaluating us as the other way around.
