Specialized engineering
when the stakes are real
Organizations call WIRL when a technical problem is expensive to get wrong — line-down risk, certification exposure, or a program where in-house teams do not carry depth across hardware, firmware, edge, and cloud together. We operate like a senior hire across disciplines: accountable, direct, and able to document decisions so a reviewer or CFO can follow the thread.
If you are staring at a multi-million-dollar exposure — yield, recall, missed window, or a redesign you cannot afford — we are the type of firm you bring in to narrow the blast radius and ship a defensible path to production.

On-device intelligence
When the problem is latency, privacy, or the cost of cloud.
Many teams can train a model; fewer can ship one that stays reliable on an MCU-class budget for power, RAM, and thermals. We work where inference has to run locally — vision, anomaly scoring, presence, and signal classification — and we align model, runtime, and hardware so the system still works when connectivity is hostile.
That is the profile of work we take when the downside of being wrong is measured in line downtime, rework, or field service — not in demo accuracy.
- Edge Optimization: Quantization, pruning, and runtime selection for TensorFlow Lite, ONNX, and vendor-native stacks (NVIDIA, NXP, Espressif)
- Constrained Pipelines: Computer vision and time-series processing bounded by real-time clock and memory limits on target silicon.
- Field Validation: Rigorous testing plans that treat drift, lighting, and vibration as core requirements — not something parked for "later phases."
Industrial IoT hardware
From schematics through DFM — built for where you actually mount it.
We design custom electronics when COTS modules or dev kits will not survive the environment, the certification plan, or the five-year BOM story. That includes multi-layer layout, power architecture, sensor conditioning, and RF paths chosen for your connectivity and emissions envelope — not for a bench photo.
- ARM-based and mixed-signal designs with manufacturing-aligned documentation and review gates
- Ruggedization, isolation, and connector strategy for agriculture, infrastructure, water, and building systems
- Early engagement with CM and test so EVT/DVT-style issues surface in the lab — not in the first truck roll
Embedded firmware engineering
FreeRTOS, bare metal, and the discipline in between.
Firmware is where “it works on my desk” dies. We ship RTOS and bare-metal programs on ARM and Xtensa cores with deterministic tasking, disciplined driver boundaries, and boot paths that respect secure update and failure recovery. FreeRTOS is a common choice; bare metal stays on the table when the schedule or safety story demands it.
If your risk is a seven-figure outage, recall, or missed window, you need engineers who have already debugged clock domains, DMA, and power states under load — not a team learning those lessons on your milestone.
- Task architecture, driver bring-up, and peripheral stacks (SPI, I2C, UART, CAN, USB)
- Bootloader layout, dual-bank / rollback strategy, and integration with OTA and provisioning flows
- Power management, watchdog, and logging that still make sense to a field tech at 2 a.m.

Secure cloud for fleets
Architecture for authentication, telemetry, and operations at scale.
Connected products fail in the seams: identity, TLS, shadow state, and who is allowed to command what. We design backends and device contracts so provisioning, telemetry, and remote control stay coherent as the fleet grows — including infrastructure-as-code and reviewable security posture.
- MQTT/TLS pipelines, device shadows, and fleet observability on AWS, GCP, and Azure IoT patterns
- Campaign-style updates, health reporting, and separation of “slow path” config from real-time device paths
- Hardening choices that survive audits and integration reviews, not just first-pass demos
Certification and BOM strategy
Regulated markets — engineering strategy, not a procurement afterthought.
When a line item can cost millions in delayed launch, failed audit, or rework, the right move is to bring in specialists who have already run the emissions room, the documentation set, and the “what happens at volume” conversation. We work with teams that do not keep RF and safety experts on payroll but cannot afford a late surprise.
That includes consumer-style compliance plus FDA-aligned and quality-system pressure when your product touches regulated data or controlled environments — documented decisions, traceable risk, and design artifacts an agency or enterprise security review can actually read.
- FCC / CE / UL-aware schematic and layout guidance; pre-compliance iteration before you burn the chamber budget
- BOM strategy: second source, lifecycle, and substitution analysis without gambling reliability
- Licensing and IP footprint as architecture inputs (not a spreadsheet discovered in month nine)
