Development Engineering

Sennos is rapidly emerging as the global leader in AI-driven sensing, analytics, and control for the Fluid, Fermentation, and Bio-manufacturing industries. With a revolutionary integration of hardware, software, and real-time multi-parametric data, we have quietly built the world’s most advanced sensing system and largest AI-powered fermentation data warehouse. By owning the entire stack—from sensing hardware to data infrastructure—we have delivered a breakthrough solution that reveals complex biological and chemical interactions, predicts precision outcomes, and enables next-generation production control.

The R&D Engineer owns a wide range of hands‑on hardware responsibilities — from sensor characterization and calibration, system validation to supplier quality and supporting new product development. This role works across multiple product lines, collaborating closely with firmware, production, and customer‑facing teams, and helps build the processes that allow Sennos to scale confidently.

On any given week you might be characterizing a new sensor module, prepping documentation for a supplier audit, running a fermentation test, or validating a new hardware assembly. If you like breadth, real hardware, and work that directly impacts a shipped product, this is a strong fit. This role is hands on and is required to be on‑site in our Durham headquarters.

Hardware Testing & Validation

Design and execute the full spectrum of hardware tests — functional, performance, limit, edge case, and longevity — across sensing products and assemblies

Conduct pressure testing up to 40+ psi, thermal stress and temperature sweep testing, fluid integrity validation, water ingress testing, and gasket lifecycle evaluation

Execute temperature sweep characterizations, multi‑point calibrations, re‑characterization of fielded sensors, and validation of calibration standards using reference equipment (Hach, YSI, Fluke, and similar)

Hardware Assembly & Lab Work

Build and kit hardware assemblies — sensor modules, board stacks, tank mounts, and probe housings — across multiple product lines

Perform soldering, connector rework, module integration, and mechanical assembly

New Product Development Support

Contribute to the development and validation of new hardware as the product line expands — including new tank mount variants, multi‑metric sensor modules, and expanded sensing capabilities such as vision and turbidity

Run early validation tests, document failure modes, and help translate prototype learnings into production‑ready processes

Write and maintain build SOPs, triage procedures, calibration documentation, and assembly instructions

Work within the ERP system (MRPeasy) for inventory, PO receipts, and shipping manifests

ultrasound‑based alcohol differentiation), investigating novel calibration approaches, assessing sensor longevity under field conditions

Bachelor's degree in Electrical Engineering, Mechanical Engineering, Physics, Chemistry, or related technical field (or equivalent years of professional experience)

3–5 years of experience in hardware R&D, product testing, or a closely related engineering role

Experience with electronics assembly and lab techniques: soldering, connector rework, mechanical assembly, fluid handling

Experience writing clear technical documentation — SOPs, test procedures, assembly instructions, and failure reports

Solid understanding of hardware testing methodologies — functional, performance, limit, and lifecycle testing

Comfort working within ERP and project management systems (MRPeasy, Jira, Confluence, or similar)

Experience with embedded systems and firmware – operation, debugging, daily usage

Experience in the brewing, food & beverage, or fermentation industry

Background in supplier quality, ISO processes, or audit preparation (SGS, UL, etc.)

Experience with pressure testing, fluid system validation, or gasket/seal testing

Familiarity with dissolved oxygen measurement or multi‑parameter water quality instrumentation

Ability to lift up to 50 pounds occasionally for equipment and sample handlingManual dexterity required for soldering, assembly work, and calibration procedures

Lab/production environment with exposure to various fluids and testing equipment

May require occasional overtime to support production schedules or testing timelines
