Senior Software Engineer

Job Description: We believe in bold ideas, diverse perspectives, and the drive to transform knowledge into impact. Here, your curiosity fuels progress, your voice shapes innovation, and your ambition helps redefine what’s possible within science and learning. We are a culture that obsesses over impact, challenges, and drives what’s next to power infinite possibilities for our customers, colleagues and society at large. About the Role: Senior Software Engineer (P3) – C++ / KnowItAll Platform Wiley Science Solutions Wiley Science Solutions builds and maintains the world’s most trusted spectral and chemical intelligence platforms. Our databases contain millions of rigorously curated spectra across mass spectrometry (MS), infrared (IR), Raman, NMR, and UV‑Vis—used every day by scientists who depend on correctness, performance, and traceability. At the center of this ecosystem is KnowItAll: a long‑lived, high‑performance Windows application that integrates spectral analysis, chemical data management, searching, and visualization across many techniques and file formats. KnowItAll is not a thin front‑end—it is a deeply engineered system that has evolved over decades and remains mission‑critical for laboratories worldwide, often running offline or in regulated environments. The Role This role is for senior C++ engineers who enjoy working on substantial, real‑world systems and improving them over time. You’ll work hands‑on in a large, mature C++ codebase (Windows / MFC) where performance, determinism, and scientific correctness matter every day. As a Senior Software Engineer, you will contribute meaningfully to the ongoing modernization and evolution of the KnowItAll platform. You’ll take ownership of non‑trivial areas of the system, refactor legacy components, and implement new capabilities—working closely with Principal Engineers and domain experts to ensure changes are correct, maintainable, and backward‑compatible. This is a role for engineers who respect legacy software, understand constraints, and enjoy making incremental improvements that add up to lasting value. What You’ll Be Doing Working in a large, long‑lived C++ codebase with significant domain history Owning features or subsystems and seeing them through design, implementation, and maintenance Refactoring complex or brittle areas to improve clarity, performance, and reliability Applying modern C++ practices where they improve safety and maintainability Supporting architectural improvements by helping modularize historically monolithic components Collaborating with other engineers and chemistry/spectroscopy domain experts What You’ll Work On Performance‑sensitive algorithms for spectral search, comparison, and analysis Data‑heavy workflows involving large binary datasets and in‑memory data structures Classic Windows application architecture (MFC) integrated with newer technologies Targeted modernization efforts that improve testability, extensibility, and long‑term maintainability You’ll work alongside senior and principal engineers who care deeply about correctness and will expect thoughtful technical decisions—not rushed solutions. What We’re Looking For Strong professional C++ experience, including debugging, refactoring, and performance tuning Experience working in large, long‑lived codebases (not just greenfield projects) Windows development experience; MFC experience is a strong plus Solid understanding of memory management, threading, and performance trade‑offs Comfort improving existing systems incrementally rather than rewriting from scratch Typically 6–10 years of professional software development experience Clear technical communication and collaborative working style Nice to Have Experience with scientific, engineering, or data‑intensive software Exposure to modernization efforts (modularization, architectural cleanup, API enablement) Familiarity with Agile development environments (e.g., JIRA), pragmatically applied Why Engineers Like This Role You work on real software used by real scientists—not disposable demos Performance, correctness, and reliability genuinely matter You’ll grow deep system knowledge and take meaningful ownership Modernization is thoughtful and engineering‑led, not trend‑driven Your work meaningfully supports scientific research and analysis If you enjoy understanding complex systems, improving them piece by piece, and building software that must be trusted, this Senior Software Engineer role offers a rare and rewarding challenge.
