About Terrestrial Bio, Inc.

Terrestrial is transforming the delivery of next-generation therapies, starting with GLP-1.

Terrestrial's proprietary Tacterra™ microarray patch (MAP) and applicator platform consists of a patch resembling an adhesive bandage, which is applied with a preloaded applicator and removed after a few minutes. Once applied, each patch delivers bioactive tips into the skin, which dissolve quickly into the body, rapidly releasing their therapeutic payload. Designed for self-administration, the temperature-stable Tacterra™ platform enables precise, controlled delivery of a wide range of therapeutics without medical sharps or refrigeration.

Terrestrial has generated strong clinical and in-vivo proof of concept across multiple molecules. For more information,

You'll own the handoff that makes or breaks a platform like ours: taking formulations from R&D and turning them into repeatable, compliant manufacturing processes. Reporting to the Director of Process Development, you'll act as the connective tissue between Research, Manufacturing, Quality, and Automation — with real influence over how our microarray patch formulations get built, optimized, and scaled. You'll also have hands-on oversight of formulation campaigns and the technicians running them, giving you both technical depth and early leadership experience.

What you'll do

• Lead cGMP formulation operations for Microarray Patch manufacturing, ensuring adherence to batch records, SOPs, and regulatory requirements
• Provide hands‑on guidance to junior staff and technicians during manufacturing campaigns; train, mentor, and evaluate personnel
• Oversee day‑to‑day manufacturing floor activities — safety, compliance, scheduling, and troubleshooting — alongside Manufacturing and Facilities
• Drive process development and optimization studies for microarray patch formulations, including excipient optimization
• Act as the liaison between Research and Manufacturing to scale formulation processes from R&D to production
• Identify and implement new technologies and assays to support continuous improvement
• Lead root cause analyses and process development investigations
• Author, edit, and review batch records, SOPs, and work instructions
• Communicate progress, issues, and results to key stakeholders

Who you are

• Engineer I - BS in Chemical Engineering, Biomedical Engineering, Chemistry, or a related discipline; 0–2 years of relevant experience (internship, co‑op, or academic research experience welcomed)
• Engineer II - BS or MS in Biological Sciences, Chemistry, Biomedical Engineering, Chemical Engineering, or related discipline, with 3+ years of relevant experience (title adjusted commensurate with qualifications)
• Strong hands‑on formulation process development experience; able to design and execute studies and analyze results independently
• Prior supervisory experience in a GxP environment preferred
• Strong grasp of Good Documentation Practices, including authoring and reviewing batch records, SOPs, and work instructions
• Excellent verbal and written communication, time management, and project management skills
• Ability to learn quickly, solve challenging technical problems creatively, and work well across diverse, multidisciplinary teams
• Strong attention to detail and root‑cause problem‑solving skills.

Compensation: The anticipated base salary range for the Engineer I position is $62,000 - $82,000. The compensation for the Engineer II position is $72,000 - $91,000. Actual compensation will be determined based on a variety of factors including experience, qualifications, and internal equity.

Onsite expectations: The majority of our roles at Terrestrial are either onsite or hybrid, which allows us to meet both business and team needs. Candidates applying must be willing to be onsite 4-5 days per week.

Location: Woburn, MA and our new, custom facility in Allston MA planned for Q4 of 2026.
