Explore managed IT01 / Our story
Callysta’s engineering story began in 2000—ten years before the company was formally incorporated.
Our software-first roots grew into embedded electronics, custom appliances, identity systems, learning technology, and smart metering. Work such as CallystaDNA and EduLabs reflects the same enduring focus: making complex technology useful in practice.
AI already supports our engineering workflow, from software and firmware to electronics and industrial design. Its application continues to expand across validation, pilot builds, and manufacturing preparation, with experienced engineers directing the work.
New tools. The same engineering discipline.
02 / What we engineer
Our strength is not a single technology. It is the ability to connect software, electronics, industrial design, and operations into one dependable solution.
Custom applications, backend platforms, and system integration built around real operational needs.
Custom electronics, firmware, connected devices, and telemetry—from the circuit board to the management platform.
Computing, networking, and storage in purpose-built hardware, continuing the multidisciplinary approach behind CallystaDNA.
Metering systems and STS prepaid-meter token generation, drawing on our experience with PLN’s prepaid vending server.
Biometrics, public-key infrastructure, smart cards, and access control—connecting trusted identity with everyday operations.
Interactive media, simulation, and virtual laboratories, building on Callysta EduLabs’ work in science and mathematics.
Proven in critical infrastructure
Our experience includes PLN’s prepaid vending server: a system that generates tokens for STS prepaid electricity meters. It brings together the software, services, and operational integration behind prepaid metering.
That experience also extends to industrial and military solutions, where software, hardware, and system integration must work together around demanding operational requirements.
Engineering facilities
CNC PCB prototyping, component assembly, 3D-printed enclosures, and engineering instruments bring designs into the physical world. Bench measurements and hardware-in-the-loop testing help us find integration issues while they can still inform the design.
Schematic capture, PCB development, firmware bring-up, measurement, and technical diagnosis.
Iterative product, enclosure, and test-article development for earlier physical feedback.
Real-device commissioning and cross-layer verification from software command to physical response.
Controlled pilot builds, repeatable procedures, and preparation for reliable manufacturing.
03 / The next chapter
AI helps us shorten feedback loops and coordinate specialist work. Requirements, design decisions, and validation stay connected, with experienced engineers responsible for the outcome.
Connected engineering tools and automation help move work between disciplines with fewer repetitive handoffs.
Keep requirements, decisions, and lessons available as the project evolves, so teams can build on earlier work.
Select models and tools around the engineering task and its validation needs, with human review of the results.
Coordinate specialist agents through bounded tasks and traceable handoffs, with engineers directing the work.
Check that software actions produce the intended physical response through hardware-in-the-loop testing.
Connect each release to its source, build, tests, and deployment record—so teams can review what changed and what was verified.
Human-directed. Evidence-driven.
Engineering judgment sets the direction. AI helps teams explore, execute, and verify—with people accountable for the outcome.
