Embedded Systems Engineering
Firmware and hardware co-design for train IT and industrial control systems, engineered under a secure development lifecycle.
- IEC 62443-4-1
- IEC 62443-4-2
- EN 50155
- TS 50701
- ISO 9001:2015
Product engineering for the embedded layer of safety- and security-critical systems: on-board rail equipment, industrial controllers, and connected devices. Development runs under a secure development lifecycle aligned to IEC 62443-4-1, so security evidence is produced as the product is built — not reconstructed afterwards.
What this service covers
Firmware & hardware co-design
Board bring-up, BSP and driver development, RTOS and embedded Linux platforms, and hardware/software partitioning decided jointly with your hardware team rather than handed over a wall.
Train IT & on-board systems
Product engineering for passenger information, condition monitoring, gateways and on-board compute — designed against rail environmental, EMC and cybersecurity requirements including EN 50155 constraints and TS 50701 context.
Industrial control systems
Control and supervisory components for industrial automation: PLC-adjacent firmware, protocol stacks (OPC UA, Modbus, MQTT), and the secure integration of legacy serial equipment into modern architectures.
Secure development lifecycle
Threat modelling, secure coding standards, static analysis gates, software composition analysis and security verification planned into the development process per IEC 62443-4-1 practices — with the documentation trail a certification audit expects to see.
Verification & long-term maintenance
Requirements-traced test benches, HIL rigs where the programme justifies them, and sustained engineering for products with 15–30 year service lives, including obsolescence and patch management.
How an embedded engagement runs
The numbering below maps to actual engagement stages — each stage has an entry criterion, a deliverable and a decision point.
- Stage 01
Requirements & architecture baseline
We start from your system requirements and constraints — environmental, safety, security level targets — and produce an agreed architecture and interface baseline before writing production code.
- Stage 02
Security context & threat model
Zones, conduits and the product's security context are defined up front. The threat model drives the security requirements that development is then verified against.
- Stage 03
Iterative development under SDL gates
Sprint-based delivery from Bengaluru with UK/Germany architectural oversight. Every increment passes static analysis, code review and unit verification gates; security-relevant changes trigger threat model review.
- Stage 04
Verification & evidence pack
Requirements-traced verification, security testing against the defined context, and assembly of the design, test and SDL evidence into a pack usable for certification or customer audit.
- Stage 05
Handover or sustained engineering
Clean handover with documentation your team can maintain — or a sustained engineering arrangement covering patches, vulnerability response and obsolescence over the product's service life.
What you walk away with
- Production firmware and hardware designs with requirements traceability end to end
- An IEC 62443-4-1-aligned evidence trail: threat model, secure coding records, verification results
- A defined vulnerability-handling and patch process for the product's service life
- Documentation a certification auditor or customer can actually work with
