Systems Engineering for Critical Infrastructure and Complex Technical Challenges You Can Trust

Whether it's SCADA modernization, embedded system recovery, or custom software development—you need someone who understands both legacy technology and modern platforms. Someone who can reverse engineer when the source code is gone, recreate firmware from scratch when recovery isn't possible, and bridge serial Modbus with cloud infrastructure.

We're systems engineers with 15+ years in defense and aerospace who tackle the problems others can't solve. We design the architecture, write the code, read the schematics, analyze the signals, and deliver solutions that work.

Problems We Solve

Real challenges facing utilities and industrial systems. If any of these sound familiar, we can help.

Legacy SCADA Running on Borrowed Time

Your RTUs still work, but the master station runs on Windows XP. The vendor's gone. The integrator retired. You know it needs upgrading, but you can't afford downtime and you can't risk breaking what's reliable.

Our Approach:

We design phased migrations that preserve your field equipment while modernizing the master. New network architecture, modern HMI, secure remote access—all while your system stays operational. We've done this for utilities still running serial Modbus from the '90s.

Integration Nightmares Between Systems

You've got three different vendors who all say their systems are compatible. None of them talk to each other. Data's getting lost, alarms aren't propagating, and nobody wants to take responsibility for making it work.

Our Approach:

We become the integration authority. We read protocol specs, debug communications, build gateways when needed, and make disparate systems work together. Modbus to DNP3, proprietary to OPC UA—we've bridged them all.

Mysterious Failures Nobody Can Diagnose

Something's failing intermittently. Maybe it's timing, maybe it's RF interference, maybe it's a protocol issue. Three contractors have looked at it. None of them figured it out. The problem's still there.

Our Approach:

We bring oscilloscopes, protocol analyzers, and actual diagnostic skills. We read schematics, trace signals, analyze timing, and find root causes. Not guesses—real engineering analysis that solves problems permanently.

Custom Hardware with No Source Code

Your motor controller works perfectly, but the original programmer is gone and you have no source code. You need new features or need to modernize it with network connectivity. Everyone you've called says it's impossible without the original code.

Our Approach:

We reverse engineer embedded systems and recreate firmware from scratch when needed. Have schematics? Great. No documentation? We'll figure out what it's doing. Want it modernized with WiFi or USB? We can do that. Prefer keeping the original architecture? That works too. You get working hardware with maintainable code.

NERC CIP Compliance Without Breaking Operations

You need to meet NERC CIP requirements, but your OT network was never designed with IT/OT segmentation in mind. You can't just throw firewalls everywhere and hope it works—these systems need sub-second response times.

Our Approach:

We design network segmentation that meets CIP requirements while respecting latency constraints. We understand both the security requirements and the operational reality of SCADA communications.

Vendors Who Don't Understand Your Constraints

The sales team promised everything. The implementation team doesn't understand industrial systems. They want to reboot servers during peak load, patch systems without testing, and implement "best practices" that would break your operations.

Our Approach:

We understand operational constraints because we've worked in mission-critical environments. We know what "five nines" actually means. We test before deploying, plan around operations, and never assume something will work—we verify it.

Projects with No Clear Requirements

Management approved the project. Budget's allocated. But nobody's defined what "done" looks like. No performance requirements. No acceptance criteria. Just "modernize the SCADA system" and a deadline.

Our Approach:

We start with requirements definition—functional AND non-functional. What does the system need to do? How fast? How reliably? What's the security posture? We define success criteria before writing code, eliminating surprises at commissioning.

What We Deliver

Full-Spectrum Engineering Capabilities

We handle the full stack—from embedded firmware and legacy protocols to modern cloud platforms and cybersecurity. Complete technical coverage from a single team that understands how all the pieces fit together.

Systems Architecture & Requirements

Define what success actually looks like before the project starts. Comprehensive requirements—functional AND non-functional. Performance, reliability, security, maintainability. Well-architected from day one.

Custom Software Development

Purpose-built applications across domains—industrial control systems, embedded platforms, data processing, and business applications. Multi-language development (C, Python, Rust, Go, Ada, 25+ more), signal processing algorithms, real-time systems, and maintainable code that delivers ROI.

Industrial Cybersecurity

NERC CIP compliance, ICS security hardening, IT/OT network segmentation. We understand the unique constraints of OT systems—can't patch immediately, can't reboot for testing, need sub-second response times.

Technical Program Leadership

Lead complex modernization programs from concept through deployment. We manage technical teams, wrangle vendors, resolve integration issues, and keep projects on track when requirements evolve or problems emerge.

System Troubleshooting

Fix problems that have stumped others. We bring oscilloscopes, protocol analyzers, and actual diagnostic skills. Root cause analysis with engineering rigor. Permanent solutions that last.

Why You Can Trust Wavelet Solutions

We Actually Do the Work

Direct access to the engineers who design the architecture, write the code, and solve the problems. No layers of project managers, no communication gaps, no finger-pointing.

Requirements Before Code

We define success criteria before starting—functional requirements, performance requirements, security requirements, reliability targets. Well-defined from day one, eliminating surprises at commissioning.

Mission-Critical Experience

"

Most project failures trace back to one of three things: unclear requirements, poor architecture, or vendors who don't understand the operational constraints. We fix all three. We define comprehensive requirements, we design solid architectures that blend proven approaches with modern technology, and we understand that utility systems can't be treated like IT infrastructure. You're in good hands.
