About Achira Labs
   
Achira Labs is a deep technology company developing innovative diagnostic and biosensor platforms to bring affordable, high-quality testing closer to patients. Our interdisciplinary teams work across microfluidics, biochemistry, optics, electronics, and mechanical design to build impactful products for healthcare.
   
 
  
Role Summary
   
We are looking for a hands-on Mechanical Engineer
 with strong prototyping skills and a hobbyist s mindset to design, build, and refine mechanical systems and automation components for our diagnostic platforms. You will be part of our hardware engineering team, contributing to rapid prototyping, iterative design, and integration of mechanical, electronic, and optical systems.  
 
  
Key Responsibilities
   - Design well constrained mechanical parts, assemblies, and mechanisms in 
CAD
(preferably SolidWorks)  - Draft manufacturing drawings as per prevailing industry standards
  - Fabricate, assemble, and refine prototypes using in-house tools like 
3D printers, laser cutters and manual machining tools
.  - Design and develop assembly fixtures, automated jigs, and enclosures, ensuring ease of manufacturing and robust performance.
  - Evaluate, improve, and troubleshoot prototypes to achieve functional, robust, and polished solutions - 
not just quick fixes
.  - Integrate mechanical designs with 
basic electronics and optical systems
, e.g., motors, sensors, lenses, and filters.  - Familiar with basic 
electronics tasks
, such as soldering, wiring, and interfacing sensors and actuators for prototype validation.  - Work closely with cross-functional teams (electronics, fluidics, and biosensor scientists) to translate requirements into working hardware and communicate trade-offs to the respective stakeholders.
  - Co-ordinate with respective vendors to clearly communicate manufacturing/sourcing constraints
  - Take ownership of assigned targets and deliver 
working prototypes within agreed timelines
, with minimal supervision.  
  
Required Qualifications & Skills
   -  
Bachelor s degree
 in Mechanical Engineering, Mechatronics, or related field.  -  
2+ years of experience in mechanical product design, new product development or prototyping;
experience in healthcare, optical, or medical device applications is a plus.  - Strong 
hands-on skills
 in prototyping, assembly, and fabrication.  - Proficiency in 
CAD
(SolidWorks preferred) for part and assembly modelling, basic simulations, and preparation for manufacturing or 3D printing.  - Strong understanding of DFx methodologies and Geometric Dimensioning & Tolerancing (GD&T) principles
  - A working knowledge of 
fundamental mechanical engineering principles
, especially related to fluid mechanics, and mechanism design.  - Familiarity with 
3D printing
, including design for printability and post-processing.  - Exposure to 
basic electronics
 - wiring, soldering, and programming microcontrollers for simple automation tasks.  - Demonstrated ability to 
build neat, functional prototypes
, with attention to finish and detail.  -  
Self-driven
, curious, and resourceful, with a hobbyist approach to building and learning new tools or techniques.  
  
Preferred Additional Skills
   - Experience working in a 
startup, maker lab, or rapid prototyping environment
.  - Familiarity with 
automation systems
, motors, actuators, and simple control systems.  - Familiarity with optical system design
  - Familiarity with Solidworks PDM would be advantageous
  - Exposure to 
fluidics or biomedical device prototyping
 is a plus but not mandatory.  
  
What We Offer
   - Opportunity to work on 
cutting-edge diagnostic platforms
 that impact healthcare accessibility.  - A 
multidisciplinary environment
 with freedom to experiment and learn.  - Access to in-house 
prototyping facilities
 including CNC machines, 3D printers, and microfabrication tools.  - A collaborative team that values 
rigor, creativity, and practical innovation
