Software Engineering Internship – AI/Agentic Systems

Boston, US /Castelldefels (Barcelona), Spain

About us

Axiomatic AI is building a new class of AI systems designed to reason with the rigor of the scientific method. By combining deep learning with formal logic and physics-based modeling, we create verifiable, interpretable AI systems that collaborate with and support human researchers in high-stakes scientific and engineering workflows. 

Our mission, 30×30, is to deliver a 30× improvement in the speed, accessibility, and cost of semiconductor and photonic hardware development by 2030. 

We aim to revolutionize hardware design and simulation in these industries and are building a team of highly motivated professionals to bring these innovations from research into commercial products.


Position overview

We are looking for an AI/Agentic Systems Intern to support the development of intelligent workflows and evaluation infrastructure for Lemma, our scientific and engineering co-explorer.

In this role, you will work on agent tool integrations, workflow orchestration, and benchmarking systems that help us build more reliable and capable AI agents.

This internship is ideal for a candidate who wants hands-on experience at the intersection of LLM applications, evaluation systems, and product-oriented AI engineering. You will contribute directly to our goals around AI tooling adoption and Lemma integrations, while working closely with researchers and engineers on real-world systems.


Your mission

  • Work on agent tool integrations and workflow orchestration for Lemma
  • Help build benchmarking, testing, and evaluation infrastructure for AI agents
  • Support experiments around tool use, agent performance, and workflow reliability
  • Contribute to engineering foundations that make agentic systems more robust, measurable, and deployable
  • Collaborate with researchers and engineers to translate early ideas into usable internal capabilities

Key requirements

  • Currently pursuing a Master’s degree preferred in Artificial Intelligence, Machine Learning, NLP, Computer Science, or a related field
  • Strong proficiency in Python
  • Familiarity with LLMs and tool-use patterns
  • Strong analytical and problem-solving skills
  • Strong communication and collaboration skills
  • Ability to work independently while contributing effectively in a team environment
  • Comfort working in a dynamic, fast-paced setting

Work model & location expectations

Work model:
On-site. Candidates are expected to be based at our Barcelona, Boston or Toronto office.

Work authorization:
Candidates must have (or be able to obtain) work authorization in one of our office locations.

Relocation support:
Axiomatic will support relocation by covering temporary housing and travel to/from the office location during the transition period.

Hiring manager & interview process

The interview process consists of four stages:

  • Culture interview
  • Technical + Hiring Manager interview (1 hour)
  • Team interview
  • Offer stage

Internship details

You will work directly with and be mentored by a global team of multidisciplinary experts pushing the boundaries of AI-assisted physics formalization.

Type:
Paid internship

Duration:
3–6 months (typically starting between June and September, depending on candidate availability)

Future opportunities:
Successful interns may be considered for full-time roles following the internship.

 


Why join us?

At Axiomatic AI, you will be working on technology that drives innovation in AI for scientific and engineering applications in line with our 30×30 mission.

This is your opportunity to contribute to the development of new AI methodologies that improve scientific modeling, reasoning, and design. You will work on research questions with both theoretical depth and practical relevance, while collaborating with a global team of engineers, scientists, and AI specialists.

We believe in pushing the boundaries of what is possible and continuously seek to redefine the intersection of AI, uncertainty-aware modeling, and scientific computation. If you're excited by technically demanding research and want to help shape the future of AI for engineering and hardware, we want to hear from you.

Worried about not meeting every qualification? Studies show that women and people of color are less likely to apply for jobs unless they meet every listed requirement. At Axiomatic AI, we are dedicated to creating a diverse, inclusive, and authentic workplace. If this role excites you but your background doesn’t perfectly match every qualification, we still encourage you to apply. You could be the perfect fit for this position or another opportunity with us.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
