Principal Engineer – Algorithm & Software Architecture (Battery Insights)

This role is part of ADI’s Automotive Business Unit , within the Battery Management Systems (BMS) organization , and sits in the Battery Lifetime Insights Systems and Solutions (BLISS) team.

BLISS develops next-generation battery insights and algorithm-driven solutions that push the boundaries of what battery systems can achieve—improving performance, extending lifetime, and enabling safer, more intelligent energy systems across automotive and electrification applications.

Position Summary

We are seeking a Principal Engineer – Algorithm & Software Architecture to own the end-to-end architecture of battery insights algorithms and their integration into production software systems.

This role combines deep algorithmic expertise with system-level software architecture leadership. The ideal candidate will define how advanced algorithmic capabilities are structured, modularized, and deployed within embedded and production environments – bridging the gap between algorithm development and full application software.

The candidate will act as a technical leader across algorithm, embedded software, and system teams, ensuring that solutions are not only analytically sound but also scalable, maintainable, and production-ready .

Key Responsibilities

Architecture Ownership

• Define and own the end-to-end algorithm and software architecture for battery insights solutions.

• Establish modular, scalable architecture patterns that enable efficient development, integration, and reuse.

• Define interfaces, data flows, and component boundaries across algorithm, embedded SW, and system layers.

Algorithm Leadership

• Drive the development of advanced battery algorithms combining signal processing, AI/ML, modeling, and electrochemistry.

• Architect algorithm frameworks and abstractions that support robust deployment across use cases and platforms.

• Ensure algorithm designs are aligned with system-level constraints and product requirements.

System & Embedded Integration

• Translate algorithm concepts into production-ready software designs suitable for embedded and real-time systems.

• Work closely with embedded SW teams to integrate algorithms into BMS and system-level software stacks.

• Drive tradeoffs across accuracy, performance, computational cost, and memory footprint.

Cross-Functional Technical Leadership

• Lead architectural alignment across algorithm, embedded software, systems, and hardware teams.

• Define and communicate technical direction, architecture decisions, and integration strategies.

• Collaborate with internal stakeholders and customers to align architecture with product and application needs.

Execution & Delivery

• Guide projects from concept through architecture definition, prototyping, validation, and deployment.

• Identify risks and drive mitigation strategies at the architecture level.

• Contribute to the development of frameworks, tools, and best practices for algorithm deployment.

Mentorship & Influence

• Mentor engineers in both algorithm development and system-level design thinking.

• Influence engineering excellence in architecture, modularity, and production-readiness.

Required Qualifications

• PhD or MS in Electrical Engineering, Mechanical Engineering, Applied Mathematics, Physics, Computer Science, or related field (or equivalent deep expertise).

• 12+ years of industry experience, including:

• Significant experience in algorithm development, and

• Proven experience in software or system architecture for complex products.

• Demonstrated ability to define and own architecture for deployed systems, not just develop algorithms.

• Strong background in multiple of the following:

• Algorithm development

• Machine learning / AI

• Signal processing and estimation

• Mathematical modeling and simulation

• Control systems

• Experience translating algorithms into production or embedded software environments.

• Strong understanding of:

• Software architecture principles (modularity, interfaces, system design)

• Embedded and real-time system constraints

• Proficiency in tools such as MATLAB/Simulink and Python (NumPy, SciPy, PyTorch , etc.).

• Proven ability to operate across cross-functional teams and complex system boundaries.

Preferred Qualifications

• Hands-on experience with battery algorithms (SOC, SOH, diagnostics, or advanced battery insights).

• Experience with Battery Management Systems (BMS) architecture and integration.

• Background in electrochemical system modeling.

• Experience defining software architectures in automotive or embedded systems environments.

• Familiarity with automotive processes such as AUTOSAR and ASPICE.

• Track record of leading multi-disciplinary architecture across algorithm and embedded software teams.

What We’re Looking For

• Architecture + depth: someone who can define system architecture while still understanding algorithm fundamentals.

• Product mindset: focused on delivering solutions that are deployable, maintainable, and scalable.

• Cross-domain leadership: able to bridge algorithm, embedded SW, and system teams.

• Ownership and clarity: comfortable taking responsibility for technical direction and architectural decisions.

• Strong communication: able to translate complex concepts across technical and non-technical stakeholders.
