ENGINEERING SERVICES

Engineering as a service.

Engineering depth for teams building specialized hardware — robotics, instrumentation, custom equipment, and replacement parts. Whether you have a defined spec, an open exploration, or an undocumented part on your bench, we can take it from concept to working hardware.

Contract Engineering

For teams with a defined problem who need execution.

Engagement model
Fixed-scope project pricing or hourly retainer for ongoing work. Scope, deliverables, and acceptance criteria agreed in writing before kickoff.
Example deliverables
  • Scoped to the project; a typical engagement includes one or two of the following rather than all:
  • Mechanical design package — CAD models, manufacturing drawings, and BOMs
  • Custom PCB design — schematic, layout, BOM, and fabrication files
  • Welded fabrication or machined parts to spec
  • Firmware or embedded software for a defined hardware target
  • Working integrated prototype with test report and assembly documentation
Typical timeline
4–12 weeks for most engagements. Projects involving custom PCB fabrication or extended test cycles run longer and are scoped accordingly.

R&D

For teams exploring new technology or a new application of existing technology.

Engagement model
Hourly with a monthly cap, or milestone-based for multi-phase efforts. Each phase ends with a written deliverable and a go/no-go decision point before the next phase begins.
Example deliverables
  • Scoped to the phase; a typical engagement produces one or two of the following rather than all:
  • Feasibility study with technical recommendation and rough cost projection
  • Breadboard or rapid prototype demonstrating the core concept
  • Test data and analysis comparing alternative approaches
  • Materials or component trade study with sourcing recommendations
  • Phase-2 development plan covering scope, cost, and timeline
Typical timeline
2–6 weeks for a feasibility study. 8–16 weeks for a full breadboard cycle. Longer programs are structured as a sequence of phased engagements rather than a single open-ended contract.

Reverse Engineering

For teams with an undocumented or obsolete part needing replication or improvement.

Engagement model
Fixed-fee per part, with optional follow-on pricing for production runs. Material analysis beyond visual and dimensional inspection is quoted separately when lab work is required.
Example deliverables
  • Scoped to the part; a typical engagement produces one or two of the following rather than all:
  • Dimensional CAD reconstruction from physical sample(s) with manufacturing drawings
  • Material identification — visual, dimensional, and basic mechanical characterization in-house; composition and metallurgical analysis through partner labs
  • Drop-in replacement part(s) ready for production, in nylon, machined metal, or welded assembly
  • Documentation package with drawings, specs, tolerances, and recommended improvements
  • Short-run production of replacement parts using our in-house capabilities
Typical timeline
2–6 weeks per part for documentation and a first article. Production runs scoped separately based on quantity and material.
What we don't do

We aren't a staffing agency or a general engineering consultancy. We engage on scoped problems with clear deliverables, where the combined manufacturing and engineering depth of our team is the reason you'd hire us in the first place. A few specific things outside our scope: Pure staff augmentation. We don't place individual engineers into a client's org chart on an hourly basis. If you need engineering hands inside your team, a staffing firm will serve you better. Open-ended consulting retainers. We work on bounded engagements with written scope and acceptance criteria. Advisory relationships without defined deliverables aren't a fit. Reverse engineering of actively patented parts without a license or a written freedom-to-operate opinion from the client's counsel. We're happy to work on parts in the public domain, but we won't put either of us at legal risk. Work outside our disciplines. Civil, structural building, chemical process, and software-only engagements without a hardware component aren't what this team is built for. If you're not sure whether your project fits, send the brief anyway — we'd rather say so in a fifteen-minute call than have you guess.

you're building.

Every project starts with a short brief. Once we've confirmed it's a fit, you'll get an account on our quoting and project portal.

Usual first response: under 24 hrs, Mon–Fri.
