01 / Our story

Experience is our foundation.
Curiosity moves us forward.

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.
Principles we carry forward
01 Innovate with purpose
02 Build through partnership
03 Think globally, deliver locally
04 Advance responsibly

Selected clients

Across industries.
Grounded in experience.

Serving customers in Indonesia and internationally across essential services, industry, and the public sector.

Our partners

Building together.
Bringing ideas to life.

Collaboration is part of how we engineer—from components and connectivity to the finished solution.

02 / What we engineer

From an idea to a system
that works in the field.

Our strength is not a single technology. It is the ability to connect software, electronics, industrial design, and operations into one dependable solution.

01

Software & integration

Custom applications, backend platforms, and system integration built around real operational needs.

02

Embedded systems & IoT

Custom electronics, firmware, connected devices, and telemetry—from the circuit board to the management platform.

03

Purpose-built appliances

Computing, networking, and storage in purpose-built hardware, continuing the multidisciplinary approach behind CallystaDNA.

04

Smart metering & STS

Metering systems and STS prepaid-meter token generation, drawing on our experience with PLN’s prepaid vending server.

05

Identity & access

Biometrics, public-key infrastructure, smart cards, and access control—connecting trusted identity with everyday operations.

06

Learning technology

Interactive media, simulation, and virtual laboratories, building on Callysta EduLabs’ work in science and mathematics.

Proven in critical infrastructure

Engineering where reliability matters.

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

Built to work beyond the screen.

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.

01

Electronics development

Schematic capture, PCB development, firmware bring-up, measurement, and technical diagnosis.

02

Rapid prototyping

Iterative product, enclosure, and test-article development for earlier physical feedback.

03

HIL & device validation

Real-device commissioning and cross-layer verification from software command to physical response.

04

Pilot & production readiness

Controlled pilot builds, repeatable procedures, and preparation for reliable manufacturing.

03 / The next chapter

Engineering intelligence.
Integrated into the work.

AI helps us shorten feedback loops and coordinate specialist work. Requirements, design decisions, and validation stay connected, with experienced engineers responsible for the outcome.

  1. 01

    Tools that work together

    Connected engineering tools and automation help move work between disciplines with fewer repetitive handoffs.

  2. 02

    Decisions that stay connected

    Keep requirements, decisions, and lessons available as the project evolves, so teams can build on earlier work.

  3. 03

    The right tools for the task

    Select models and tools around the engineering task and its validation needs, with human review of the results.

  4. 04

    Specialist work, clear ownership

    Coordinate specialist agents through bounded tasks and traceable handoffs, with engineers directing the work.

  5. 05

    Verified on real hardware

    Check that software actions produce the intended physical response through hardware-in-the-loop testing.

  6. 06

    Know what was delivered

    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.

Experience guides.
AI amplifies.

Engineering judgment sets the direction. AI helps teams explore, execute, and verify—with people accountable for the outcome.
