We are seeking a highly experienced Staff Mechanical Engineer to contribute to the development of Sarmal’s next-generation IVD instrumentation and consumable systems. The ideal candidate has 8+ years of industry experience, strong mechanical design fundamentals, and experience developing complex hardware in biotechnology, life sciences, diagnostics, or related instrumentation environments.

This is a highly hands‑on technical role focused on mechanical design, system development, prototyping, and problem solving. The engineer will own major mechanical components and subsystems while working closely with scientists and engineers across mechanical, electrical, fluidics, software, and assay development.

Experience developing biotech instruments, disposable consumables, microfluidic systems, or automated biochemical workflows is highly desirable.

Key Responsibilities

• Design and own complete subsystems, components, and assemblies within Sarmal’s IVD instrument platform.


• Translate system, assay, and operational requirements into practical mechanical architectures and detailed designs.


• Develop concepts, prototypes, breadboards, fixtures, and production‑intent hardware through iterative design and testing.


• Perform detailed mechanical design including 3D CAD, tolerance analysis, GD&T, material selection, mechanism design, and design for manufacturing and assembly.


• Drive the performance characterization and improvement of test platforms / breadboards for rapid evaluation of various instrument/consumables architectures for the automation of biochemistry workflows.


• Assist and guide teams in establishing best practices for development‑scale consumables manufacturing, encompassing fluidic devices, functionalized solid substrates, and reagents.


• Interface with suppliers or external collaborators.

Qualifications

• Strong mechanical design fundamentals and demonstrated experience developing complex hardware.


• Advanced experience with 3D CAD, tolerance analysis, GD&T, mechanism design, materials selection, and design for manufacturing/assembly.


• Demonstrated understanding of integrated fluidic-based platforms for complex assays or biochemical processes.


• Demonstrated ability to independently own complex mechanical components and subsystems.


• Experience with experimental design and execution, including DOEs and root cause analysis.


• Experience with microfluidic devices for nucleic acid applications is a plus.


• Experience with manufacturing systems and workflows is a plus.
