Employees are our greatest asset, which is why we share our company's profits to celebrate our collective success.
As a privately-owned company, we are proud to invest significantly in our community and in our own growth, focusing on long-term business success.
We are proudly American!

You'll love our Engineering Team!

Join a team where your engineering talent directly supports the people who protect and serve. At OTTO Engineering, we design and build innovative communications and power‑management products used by Public Safety professionals and Military teams around the world. You'll help create rugged, reliable, and innovative products that professionals depend on every day. If you're excited by meaningful engineering challenges and the chance to build technology that truly matters, this role is a great fit.

Specifically, we are seeking experience with …

PTC CREO or similar parametric CAD tools
Plastics, elastomers, die‑cast metals, overmolding, and mechanical integration with PCBs
DFM/DFA, tolerance analysis, and mechanical verification testing

As our Mechanical Engineer II you will develop and support ruggedized communication products—including speaker microphones, PTT devices, tactical headsets, and electromechanical assemblies—used in mission‑critical environments. This role requires strong mechanical design skills, hands‑on prototyping, and the ability to collaborate across engineering, manufacturing, quality, and supply chain teams. The Mechanical Engineer II works independently on assigned components or subassemblies with guidance from senior engineers as needed.

The Mechanical Engineer II will:

Develop mechanical design concepts and performance specifications that meet customer, marketing, and environmental requirements (IP, MIL‑STD, drop, vibration, thermal).
Perform engineering analyses including tolerance stack‑ups, stress modeling, material selection, and statistical evaluation of test data.
Create 3D CAD models and detailed drawings of components and subassemblies using CREO.
Prototype, test, and iterate mechanical designs; support mechanical and environmental verification testing and document results.
Prepare engineering documentation, including drawings, BOMs, ECNs, specifications, and cost estimates for tooling and mechanical components.
Collaborate with manufacturing, quality, supply chain, and suppliers to ensure DFM/DFA, cost‑effectiveness, and production readiness.
Support production and quality teams in resolving design or process issues on existing products; participate in MRB activities and discrepant material reviews.
Coordinate project activities across internal teams and vendors; communicate risks and recommend corrective actions.
Assist with other related duties as required or assigned.

About you - What you'll bring to the table:

Bachelor's degree in Mechanical Engineering or related field.
Minimum 2 years of mechanical engineering experience in product development.
Proficiency with PTC CREO or similar parametric CAD tools.
Strong understanding of plastics, elastomers, die‑cast metals, overmolding, and mechanical integration with PCBs.
Experience with DFM/DFA, tolerance analysis, and mechanical verification testing.
Ability to work independently in a fast‑paced, hands‑on engineering environment with strong follow‑through and communication skills.

What OTTO offers for this specific position:

The hiring range listed in this posting is what we, in good faith, anticipate relying on when confirming a base salary for this position; exceptions may be considered for highly experienced candidates with multiple years of at-level experience.

Target base salary hiring range: $75,000 to $90,000, based on qualifications and experience.
Profit Sharing Bonus - OTTO believes that it's fair to share the profits that the employees help to make; profit sharing is distributed to employees twice a year. OTTO's profit sharing plan is paid at the discretion of the company and is not a guaranteed bonus or any part of a compensation plan.
Vacation: 80 hours - vacation time is earned on the anniversary date.
