Consulting engineers since 2014 · Cape Town

We solve hard engineering
problems and build things
that work.

BMEC is a bespoke engineering consultancy. From a quick design review to a full product development programme spanning mechanical, electronic, software and regulatory work, delivered by one multidisciplinary team.

Clients we have worked with across four continents

What we do

Engineering support for difficult technical problems.

Clients come to us with technical challenges they cannot resolve internally: a stalled vendor, a prototype that cannot be manufactured, a device that needs certification, or a product that needs to be engineered properly from the start. We assess the problem, give clear advice and deliver the work.

Projects range from a single design task to a full development programme. If the work needs one discipline, you pay for one. If it needs several, one team is accountable for all of them.

  • Direct advice. We tell you what we think, including when an approach will not work or when a supplier's proposal does not stand up.
  • First-time quality. We model, simulate and run tolerance analysis before we build. Complex systems have passed CE certification on the first attempt.
  • Founder involvement. Raphael and Heidi work on projects directly. There is no account manager between you and the engineers.
  • You own your IP. Every engagement is structured so that the IP is yours from day one.

Capabilities

Five disciplines in one team.

Mechanical, electronic, firmware, software and medical engineering in one practice, from first concept through to long-term support in the field.

fCTO

Fractional C-suite techno-commercial support

Senior technical leadership without a full-time hire: directorship, due diligence, risk management, IP and innovation strategy, and investment sourcing.

  • Due diligence
  • IP & innovation
  • Risk management

Software

Mobile, web, cloud and embedded

Full-stack engineering across application, embedded and cloud, from mobile apps used in the field to firmware on medical devices and the cloud services behind them. We also build AI into client systems and our own.

Not sure which you need?

Most projects span more than one discipline. Tell us about yours and we will advise on what it requires.

Selected work

Products running in the field, some for over a decade.

Water treatment, agritech, medical devices, IoT and assistive technology, from concept to clinical use and from prototype to production.

ArcStation

Brought in to recover a failing vendor relationship, then contracted to design ArcAqua's flagship industrial ozone sanitation system. CE certified on the first attempt, with hundreds of units deployed and still in service more than ten years later.

SmartSpreader

A nine-year relationship across five product generations. What began as a GPS speed-control brief became a precision-agriculture platform spanning electronics, firmware, mobile, web and cloud, which BMEC continues to develop and maintain.

Draught Guardian

A beer-tap monitoring startup asked us for a modest hardware revision. We recommended a new architecture instead, which removed the most expensive component and reduced unit cost by roughly a factor of ten.

QMAX

A permanent implant for the treatment of glaucoma, taken from concept through prototyping, IP protection, and pre-clinical and clinical device production. Currently in human-stage trials.

"A jack of all trades is a master of none, but oftentimes better than a master of one."

One client relationship has spanned 26 statements of work over more than a decade. Another has been in continuous production with us since 2017. Software and hardware we designed ten years ago are still in service. We have filed PCT patents, and clients retain full ownership of their IP.

How we work

A clear path from idea to deployed product.

Every engagement is a fixed-scope step on the same six-phase path. You can join at any phase and stop at the end of any one.

  1. Phase 01

    Discover

    Techno-commercial due diligence, technology readiness assessment, platform and tooling evaluation, IP strategy and regulatory planning, leading to a clear requirement specification.

    In practice: Draught Guardian →
  2. Phase 02

    Architect

    The high-level technology decisions: software architecture, hardware component selection and automation system specification. These are the decisions that are most expensive to change later.

    In practice: SmartSpreader →
  3. Phase 03

    Design

    The deliverables: code, schematics, PCB layouts, CAD models, manufacturing packs, BOMs and production documentation.

    In practice: Simba Pediatric Bed →
  4. Phase 04

    Implement

    Production from low to high volume, sourcing and procurement, assembly and full-stack systems integration.

    In practice: HSBP →
  5. Phase 05

    Test

    Bench, lab and field verification and validation, plus regulatory approval and trial support, including cadaveric, animal and human studies.

    In practice: QMAX →
  6. Phase 06

    Deploy

    Rollout, technical training, production management, issue resolution, obsolescence management and long-term lifecycle oversight.

    In practice: ArcStation →

In-house

Our workshop equipment.

Prototyping, machining, board assembly and clean-bench work are done in-house, which shortens iteration cycles and lets us find problems early.

In the workshop

We build what we design.

Designs are modelled and simulated before they are built, then etched, machined, populated and assembled, much of it in-house. This is how we get complex systems through certification on the first attempt.
