Senior Software Engineer Full Description

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 UVâVisâused every day by scientists who depend on correctness, performance, and traceability.

At the center of this ecosystem is KnowItAll: a longâlived, highâperformance Windows application that integrates spectral analysis, chemical data management, searching, and visualization across many techniques and file formats. KnowItAll is not a thin frontâendâit is a deeply engineered system that has evolved over decades and remains missionâcritical for laboratories worldwide, often running offline or in regulated environments.

The Role

This role is for senior C++ engineers who enjoy working on substantial, realâworld systems and improving them over time. You'll work handsâon 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 nonâtrivial areas of the system, refactor legacy components, and implement new capabilitiesâworking closely with Principal Engineers and domain experts to ensure changes are correct, maintainable, and backwardâcompatible.

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, longâlived 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

Performanceâsensitive algorithms for spectral search, comparison, and analysis
Dataâheavy workflows involving large binary datasets and inâmemory data structures
Classic Windows application architecture (MFC) integrated with newer technologies
Targeted modernization efforts that improve testability, extensibility, and longâterm maintainability

You'll work alongside senior and principal engineers who care deeply about correctness and will expect thoughtful technical decisionsânot rushed solutions.

What We're Looking For

Strong professional C++ experience, including debugging, refactoring, and performance tuning
Experience working in large, longâlived codebases (not just greenfield projects)
Windows development experience; MFC experience is a strong plus
Solid understanding of memory management, threading, and performance tradeâoffs
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 dataâintensive 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 scientistsânot disposable demos
Performance, correctness, and reliability genuinely matter
You'll grow deep system knowledge and take meaningful ownership
Modernization is thoughtful and engineeringâled, not trendâdriven
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.

We power infinite possibilities.

For more than 200 years, we've transformed knowledge into discoveries that shape the world. Today, our global team of innovators, creators, and experts is driving what's next in science, education, and publishingâcreating impact that reaches everywhere.

We're not just observers of progress. We're the ones accelerating scientific breakthroughs, advancing learning, and sparking innovation that redefines entire fields and improves lives.

Here, your talent matters. Your ideas have room to grow. And your work creates breakthroughs that can change everything.
