Research Associate, In Vivo Pharmacology

Position Overview

Actithera is a radiopharmaceutical biotech company, co-headquartered in Oslo and Cambridge, Massachusetts, founded in 2021. The company applies a chemistry-first approach to design next-generation radioligand therapies (RLTs) that deliver potent, tumor-focused radiation while sparing healthy tissue—guided by an isotope-agnostic and platform-enabled strategy to optimize tumor retention and therapeutic index. Actithera’s vision is rooted in precision molecular design and a deeply collaborative culture, with a shared mission to transform the lives of cancer patients through innovative science.

We are seeking a Research Associate to support in vivo pharmacology activities conducted at external animal facilities in Oslo. This is a hands-on technical role, focused on animal handling, dosing, monitoring, and tissue and organ collection to support preclinical radioligand therapy studies. The position is well suited for a skilled Research Associate who enjoys working directly with animals and contributing to high-quality, compliant in vivo studies.

Key Responsibilities

Perform routine animal handling and husbandry-related experimental tasks in compliance with approved study protocols and animal welfare regulations.

Execute in vivo dosing procedures including intravenous (tail vein), intraperitoneal, and subcutaneous injections.

Monitor animals for clinical signs, body weight, tumor growth, and welfare, and accurately document observations.

Perform animal sacrifice and necropsy, including tissue and organ collection for biodistribution, histology, and other ex vivo analyses.

Support biodistribution and pharmacology studies, including tissue weighing, gamma counting preparation, and sample handling.

Assist with preclinical imaging workflows as required.

Maintain accurate experimental records, logs, and documentation in accordance with internal SOPs and regulatory requirements.

Ensure compliance with animal welfare regulations, radiation safety requirements, and internal SOPs, actively promoting best practices and a safe laboratory environment.

Assist with general laboratory and animal facility tasks, including preparation of dosing solutions, consumables management, and equipment cleaning.

Qualifications

BSc or MSc in life sciences, veterinary nursing, animal technology, biomedical sciences, or a related discipline.

Certified and experienced in rodent handling and in vivo dosing procedures, including IV (tail vein), IP, and SC injections, in accordance with FELASA/CAREiN training and animal welfare regulations.

Practical experience working in an animal facility with mice.

Experience with animal tissue collection for preclinical studies.

Hands-on experience with blood sampling techniques in rodents and oral gavage for dosing administration is considered an advantage.

Familiarity with radiopharmaceutical handling or radioactive work is an advantage; training can be provided.

Ability to work with advanced laboratory and preclinical research equipment, including preclinical imaging systems.

Strong attention to detail, reliability, and ability to follow protocols precisely.

Comfortable working in a regulated environment with strict safety and documentation requirements.

Ability to work effectively as part of a team and communicate clearly with internal scientists as well as external facility staff and partners.

What We Offer

Opportunity to work at the forefront of radioligand therapeutics within a highly collaborative, science-driven team where patient impact comes first, curiosity is encouraged, expertise is shared, and people succeed together through humility, integrity, and true collaboration.

Competitive compensation and benefits package.
