Job Description

Job Summary

Seeking an experienced Senior C++ Engineer to join the team building our next-generation embedded writer platform. The selected candidate will be responsible for porting core application logic from a legacy real-time embedded platform to a modern embedded Linux system, and for building the regression-testing infrastructure that proves the ported software behaves identically to the original. This role requires strong expertise in modern C++ development, cross-platform porting, protocol and file-format design, and test-harness engineering, applied to software that produces a legally significant data record and therefore cannot tolerate correctness regressions.

Key Responsibilities

Port core application and domain logic from a legacy RTOS-based C/C++ codebase to a Linux-based embedded platform, preserving exact functional behavior.
Design and build an automated regression harness that replays historical input data through both the legacy and ported implementations and verifies bit-exact output equivalence; integrate this harness into continuous integration so every change is verified automatically.
Reconcile divergent copies of shared logic that evolved independently on different platforms into a single, verified, canonical implementation.
Design and implement serialization and communication protocol logic (framing, checksums, versioning) ensuring wire-level compatibility with existing external client software.
Rework legacy file- and storage-management logic that is tightly coupled to a proprietary real-time operating system into a clean implementation on a standard Linux filesystem, while preserving on-disk data formats and data-safety guarantees (no data loss on crash or power loss).
Port cryptography and data-integrity logic, and extend it to support a tamper-evident, cryptographically signed data journal.
Port audio codec/compression logic into a new platform-appropriate audio pipeline. • Design clean internal interfaces (abstraction seams) that isolate ported business logic from platform-specific concerns, without building a full compatibility-emulation layer.
Collaborate with platform, firmware, QA, and program leadership to align on process boundaries, data-safety guarantees, and real-time performance budgets.
Participate in design and code review, with particular attention to correctness on the legally-sensitive data-capture path.
Utilize modern AI-assisted development tools to accelerate large-scale code translation and test generation, while applying independent engineering judgment to verify correctness rather than trusting generated output at face value.
Support the product from early architecture through production release

Required Qualifications

Bachelor's Degree in Computer Engineering, Software Engineering, Computer Science, or related field (or equivalent experience).
8+ years of professional C++ software development experience, including production/shipping systems. • Strong experience with modern C++ (C++14/17/20).
Demonstrated experience porting or migrating a large existing codebase across platforms or operating systems (e.g., RTOS to Linux, or similar cross-platform migration).
Experience designing or implementing serialization formats or communication protocols (framing, checksums, versioning, backward compatibility).
Solid understanding of concurrent/multithreaded programming.
Hands-on experience with Linux operating systems in an embedded or application context.
Strong Object-Oriented Programming (OOP) and software design skills.
A test-first, verification-driven approach to correctness, with experience building or operating automated regression or golden-master style test harnesses.
Excellent troubleshooting and debugging skills.
Demonstrated, hands-on effectiveness with AI-assisted software engineering tools (agentic coding assistants, AI-based code review), with clear judgment about when to trust generated output and when it requires independent verification.
Experience using Git for version control and standard issue-tracking tools for project/task management.

Preferred Qualifications

Experience with embedded cryptography, data integrity, or licensing/security subsystems. • Experience with audio codec integration or digital signal processing basics.
Experience with hash-chained, append-only, or tamper-evident log/journal data structures.
Familiarity with embedded Linux storage semantics (journaling filesystems, write-through/O_SYNC data-safety patterns, flash/eMMC wear considerations).
Prior experience in a regulated, safety-critical, or legal/records-integrity software domain.
Experience mentoring engineers and contributing to software architecture decisions.
Experience working in Agile development environments.
