Company Overview
We are a forward-thinking tech startup, founded by experienced technology, security, and design specialists with four successful exits. Frustrated by the lack of trust in traditional messaging platforms — particularly in business communications — we created a new standard: a platform where users retain full control of their data, not the platform owner.
Our product empowers businesses and individuals to communicate securely and privately, with industry-leading innovations such as end-to-end encryption, geofencing, and continuous facial recognition — verifying not just the device but the actual person engaging with it.
About the Role
We are looking for a Technology Intern with a strong academic background and passion for machine learning, computer vision, and advanced biometric systems. You will work directly with our senior technology team on projects that enhance and extend our platform’s capabilities, particularly around biometric authentication and object recognition using machine learning.
We are looking for tenacious individuals with an eye for detail, a deep love for technology, and the courage to push new ideas forward. Ideal candidates are the ones who often lead technical projects among their peers — bold, innovative, yet able to work within a focused plan to drive real results.
If you’re excited about building AI and machine learning solutions in a security-first environment, and want to work on cutting-edge real-world applications, we want to hear from you.
Key Responsibilities
Research and develop machine learning models for biometric authentication (facial recognition, object identification).
Explore and experiment with frameworks such as TensorFlow and other modern ML libraries.
Support the optimization and integration of AI/ML models into real-time mobile and desktop applications.
Collaborate with engineering and design teams to deliver practical, scalable technology solutions.
Analyze system performance and model accuracy; recommend improvements based on findings.
Stay up-to-date with emerging technologies in AI, computer vision, and cybersecurity.
Ideal Profile
Postgraduate or final-year graduate student specializing in Machine Learning, Artificial Intelligence, Computer Vision, or related fields.
Experience working with TensorFlow and familiarity with other ML frameworks.
Strong interest in biometric systems, object identification, and applied AI.
Analytical mindset, highly detail-oriented, and motivated to solve complex problems.
Courageous in proposing new solutions and rigorous in evaluating them.
Comfortable working in a fast-paced, startup environment where innovation is constant.
Strong communication skills and ability to work collaboratively with cross-functional teams.
Internship Details
Duration: 6 months
Location: Remote (preferably UK or Portugal, GMT time zone), with the possibility of working onsite in Portugal.
Compensation: £1000-£1200 monthly
This is not a theoretical exercise — it’s an opportunity to apply your knowledge of machine learning and biometrics to real-world, high-impact problems in a company that’s redefining secure communication. If you have the ambition, resilience, and technical ability to lead at the cutting edge, we look forward to hearing from you.
Traineeship jobs are structured programs that combine learning and practical experience, helping you gain the skills needed to enter the workforce.

Some traineeship jobs offer stipends or salaries, while others are unpaid. On theInterna you can whether the internship is paid or not before you apply.
Absolutely! We encourage you to apply for about 5 opportunities initially which really align to your interests. It is better to have fewer but more tailored applications
Not necessarily. Many traineeship jobs are designed for beginners and focus on skill development but make sure to really demonstrate (quantitatively where possible) your skills and achievements in your CV.
Traineeship jobs come in many forms—tech, marketing, sales, customer support, engineering, and more. Some focus on creative skills, others on business or data. You can filter by field or interest when browsing listings on theInterna.
It depends on the employer. Some roles require local language skills (like Spanish or French), while others only ask for fluent English. Each listing will mention language requirements clearly, so check before applying.
Yes, you can. theInterna typically works with students in their final year or those who graduated recently. If you’ve recently completed your degree and are looking to gain hands-on experience, a traineeship is a great next step.
Yes, especially in marketing, software, and customer experience roles. Many companies now offer remote traineeships or hybrid models, allowing flexibility if you can’t relocate.
Traineeships are often structured with training modules and soft skills development, while internships tend to focus more on workplace immersion. Traineeships may also lead to qualifications or support services.
Many traineeship jobs serve as a stepping stone to a permanent role. Some companies hire top-performing trainees or extend their contracts if there’s a good fit.
Typically, you’ll need an updated CV, a short motivation letter, and any relevant academic or work references. Some roles may ask for a portfolio or language proof.
Yes, if you’re working in a country where you’re not a resident. Visa types vary by country and job duration. theInterna provides guidance or links to help with the visa process.
Most traineeships range from 20 to 40 hours per week. Full-time roles are common, but some employers offer part-time schedules, especially for students or remote placements.
By interning at a partner startup of theInterna you will be sure to get real business exposure and give you the right grounds to be able to excel when there.
