About VNT Technologies

VNT Technologies is a quantitative research and technology firm focused on developing algorithmic trading infrastructure. We combine mathematical modelling, software engineering, and low-latency technologies to build systematic trading architecture for financial markets.


If you’re excited about solving hard technical problems, working with real-time systems, and seeing your code impact markets, you belong with us.


Internship Overview

As a DeFi Engineering Intern, you will gain practical experience contributing to the systems that support our on-chain and off-chain trading infrastructure. Working alongside experienced engineers, you will assist in developing and improving components of our crypto trading stack—from smart contracts and on-chain interactions to backend services that connect with DeFi protocols, exchanges, and market data sources.


Throughout the internship, you will be involved in real technical tasks and collaborative projects that help power our trading operations. This role offers an inside look at how decentralized finance infrastructure is built and maintained, while giving you the chance to strengthen your skills in blockchain development, system design, and high-performance trading environments.


How You Will Make an Impact

  • Design, implement, and review secure smart contracts (Solidity, Rust) for on-chain applications, focusing on performance, cost efficiency, and security.
  • Build and maintain high-performance Rust services that connect blockchain networks with off-chain systems such as data pipelines, analytics tools, and backend infrastructure.
  • Develop monitoring, simulation, and testing tools to ensure system reliability and performance.
  • Research emerging blockchain technologies and protocols to identify new opportunities for system improvements.
  • Collaborate with engineers and researchers to explore innovative applications within decentralized finance and digital asset ecosystems.


What You Bring to the Team

  • Currently pursuing a degree in Computer Science, Engineering, Mathematics, Physics, or a related technical field.
  • Strong understanding of data structures, algorithms, and software engineering fundamentals
  • Proficient programming in at least one systems or backend language such as Rust, C++, Go, Python, or Java.
  • Interest in blockchain technology, distributed systems, or financial technologies.
  • Curiosity and eagerness to learn new technologies, with a proactive mindset.
  • Ability to write clean, maintainable code and reason about system design.


We Would Consider as an Advantage

  • Experience with smart contract development (Solidity, Rust, Vyper, Move, etc.).
  • Familiarity with blockchain systems or Web3 development.
  • Understanding of DeFi protocols such as decentralized exchanges, lending platforms, or liquidity pools.
  • Interest in financial markets or digital assets.
  • Experience with cloud platforms (AWS, GCP, or Azure) or building backend services.


What to Expect During the Internship

  • Meaningful projects: each intern leads a high-impact engineering project focused on building, improving, or scaling our algorithmic trading infrastructure.
  • Mentorship & collaboration: you’ll work closely with experienced software engineers who provide hands-on guidance and care deeply about code quality, system design, and your professional growth.
  • Learning & exposure: gain practical exposure to low-latency systems, trading infrastructure, data pipelines, and the full lifecycle from design and implementation to production deployment.
  • Ownership & impact: this isn’t a sandbox environment- well-designed solutions can be deployed to production and directly support our trading systems.


Life at VNT Technologies

  • Our ambitions are sky-high but calculated. Our goal is to become one of the great quantitative research firms on this continent, and we fully recognize the magnitude of that challenge.
  • Our team is shaped by diverse backgrounds and career paths. Some bring strong academic credentials - graduates of Cambridge and Oxford, medalists in International Olympiads, and PhDs. Others built exceptional expertise through hands-on experience and deep curiosity. What unites everyone is a passion for solving hard problems.
  • We offer strong compensation, a fascinating business domain, and an unlimited supply of deep and exotic technical challenges.


What We Offer

  • Salary: €4,000 gross per month.
  • Structured and fast-paced 6-week program.
  • Hands-on exposure to high-performance engineering.
  • Support from mentors who want to see you succeed.
  • Real ownership and real impact from day one.
  • A friendly, collaborative culture where good ideas can come from anyone.
  • Office at the heart of the business district - “Europa” Business Center, Vilnius, Lithuania.


Interns who demonstrate outstanding performance throughout the program will be offered a full-time role at VNT Technologies.
