Founding Team Mechanical Engineer – Product Development

Position: Mechanical Engineer – Product Development – Founding Team

Location: Detroit, Michigan

Company: Asterisk Green Inc. -

A sustainability-focused engineering startup developing intelligent hardware systems for building efficiency and performance.

Position Overview : Asterisk Green Inc. is seeking a Mechanical Engineer to support early-stage development of an intelligent hardware system. The role focuses on hands-on mechanical design, prototyping, and testing, and is well suited for candidates interested in applied R&D and real-world deployment of physical systems. While initially focused on a primary product initiative, responsibilities may evolve over time, and the engineer may contribute to additional projects as the business demands. This is an early-stage startup role that requires comfort working in a fast-moving environment, taking initiative beyond a narrowly defined scope, and supporting cross-functional needs as required.

Responsibilities

• Design mechanical components and assemblies for a compact electromechanical system

• Develop CAD models, drawings, and documentation for prototyping and iteration

• Build and test prototypes using methods such as 3D printing, CNC machining, and sheet-metal fabrication

• Support testing related to airflow, thermal behavior, noise, reliability, and installation usability

• Collaborate with electrical, electronics and software contributors on system integration

• Mentor and support university-based engineering projects, including senior design or sponsored research efforts

• Contribute to grant applications, investment materials, and project documentation

Qualifications

• Bachelor’s degree in Mechanical Engineering or a closely related field

• Strong fundamentals in mechanical design, materials, and thermos-fluids

• Experience with CAD and CAE tools (SolidWorks, Creo, ANSYS, COMSOL, Autodesk CFD, MATLAB etc)

• Hands-on experience with physical prototyping and testing Strongly Preferred

• Master’s degree in mechanical engineering or a related discipline

• Experience with electromechanical, HVAC, or building-related systems

• Coursework or project experience in mechatronics, robotics, or integrated mechanical–electrical systems

• Exposure to product development, research labs, or startup environments

Position: Electronics Design Engineer (Sensors & Embedded Hardware) – Founding team

Location: Detroit, Michigan

Company: Asterisk Green Inc.

- A sustainability-focused engineering startup developing intelligent hardware systems for built space efficiency and performance.

Position Overview : Asterisk Green Inc. is building a next-generation smart HVAC system that embeds intelligence directly into airflow hardware. We are seeking an Electronics Design Engineer to own sensor selection, circuit design, and early-stage hardware bring-up as we move from system architecture to working prototypes. This is a hands-on engineering role for someone who has designed, built, and debugged real hardware—not just supported it. The role is well-suited for an engineer comfortable operating in an early-stage startup environment, taking initiative beyond a narrowly defined scope, and supporting cross-functional needs as required.

Responsibilities

• Electronics & Sensor Architecture

• Identify, evaluate, and down-select sensors (e.g. airflow, temperature, pressure, humidity)

• Define electronics architecture from sensor → MCU → power → communications

• Make tradeoffs across accuracy, power consumption, cost, and supply availability

• Circuit & PCB Design

• Design analog and digital circuits for sensor integration, signal conditioning, and power management • Own schematic capture and guide PCB layout (or review external layout work)

• Hand solder electronic components to facilitate rapid prototyping

• Ensure DFM/DFT considerations are built in from the start

• Prototyping & Bring-Up

• Lead board bring-up, debugging, and validation

• Script firmware (C/C++, Python) to test the boards

• Develop test plans to characterize sensor performance and system robustness

• Support rapid iteration cycles from bench prototype to enclosure-integrated hardware

• Suppliers & Manufacturing Interfaces

• Coordinate with sensor vendors, PCB fabrication/assembly partners, and component suppliers

• Support BOM optimization, second-sourcing, and early cost-down strategies

• Cross-Functional Collaboration

• Work closely with mechanical designers (airflow paths, enclosures)

• Collaborate with firmware/software contributors on interfaces and requirements

• Generate documentation supporting patents, grants, and early certifications Qualifications

• BS or MS in Electrical Engineering, Electronics Engineering, or a related field

• 2+ years of hands-on electronics hardware development

Demonstrated experience with:

• Sensor integration and evaluation

• Analog and mixed-signal circuit design

• Low-power electronics

• PCB design and bring-up

• Comfortable owning hardware from concept → prototype → iteration

• C/C++ and Python programming

Strongly Preferred

• Master’s degree in electrical or electronics engineering or a related discipline

• Experience with electromechanical, HVAC, or building-related systems

• Coursework or project experience in mechatronics, robotics, or integrated mechanical–electrical systems

• Exposure to product development, research labs, or startup environments

• Embedded systems experience (MCUs, SPI/I²C/UART)

• Experience with environmental sensing or IoT hardware using 24V power and Industrial Protocols (RS485)

• Exposure to EMC/FCC pre-compliance considerations.

Physical & Work Environment

• Ability to work in a hardware prototyping, laboratory, or workshop environment

• Ability to safely use common hand tools and light shop equipment

• Ability to lift and carry items weighing up to 25 pounds, with or without reasonable accommodation

• Reasonable accommodations may be made to enable individuals with disabilities to perform essential functions

Compensation & Work Authorization

• Equity-based compensation

• Visa sponsorship is available for qualified candidates, subject to eligibility and applicable regulations
