Carbelim is an IIT-Madras and IIM-Lucknow backed climate-tech start-up pioneering
nature-based carbon capture
solutions using advanced microalgae photobioreactors. Our AI-driven systems purify polluted air, capture CO?, and transform emissions into valuable bio-based products.
As a climate-tech company, our products are centred around
air and water environmental monitoring
, where precision, reliability, and long-term stability are critical. We are looking for a professional who
aligns with our mission
, understands our vision, and can take ownership of
end-to-end product delivery
.
IMPORTANT: Please read the initial project requirements for this position, as you will start with these and progressively move forward:
Role Overview
We are seeking a
highly professional, senior-level Embedded Systems Engineer
who can
independently
lead the design, development, and deployment of
sensor-rich IoT devices
-- from
concept to mass production
, including compliance and regulatory approvals. Our immediate focus is on
advanced environmental sensing systems
for our photobioreactors and clean-air solutions. However,
this role is also future-facing
:
Future Readiness
We expect this engineer to play a
key role in our upcoming next-generation products
, which may include:
Miniaturised environmental devices
with dense sensor integration.
Wearable devices
capable of monitoring AQI and other environmental parameters.
Compact portable AQI monitors
and specialised monitoring systems for urban, industrial, and personal use.
New sensor-driven innovations
aligned with our climate-tech mission.
The selected candidate must be capable of:
Designing
compact, high-density PCBs
for small form factors.
Integrating
MEMS air quality sensors
and miniature particulate matter sensors.
Managing
power optimisation
for battery-based or wearable devices.
Working with
flex-PCBs, low-profile components
, and miniaturised connectors.
Ensuring
accuracy, reliability, and compliance
even in constrained designs.
Key Responsibilities
Lead
end-to-end product development
-- from system architecture and component selection to prototyping, validation, certification, and
scaling to full production
.
Select, integrate, and calibrate
environmental sensors
(air & water).
Implement
sensor communication protocols
(IC, SPI, UART, RS485, Modbus RTU, SDI-12, CAN) and apply
signal conditioning
for high accuracy.
Develop
embedded firmware
(C/C++ or Rust) with deep MCU knowledge -- low-power modes, interrupt handling, DMA, OTA updates, secure boot, and self-diagnostics.
Design
multi-layer PCBs
optimised for compactness, manufacturability (DFM/DFT), and noise immunity.
Integrate displays ranging from small OLED/TFT panels to large industrial touchscreens.
Ensure
compliance
with CE, FCC, EMI/EMC, and IP65/IP66 standards.
Collaborate with mechanical designers for enclosures, waterproofing, anti-fouling, and thermal management.
