About Nutrient

At Nutrient, we're revolutionizing how the world works with documents. Our tools transform static files into intelligent, secure workflows, empowering businesses to innovate faster and smarter. Trusted by thousands of organizations across 80 countries, including Fortune 500 companies and public sector leaders, our platform supports nearly a billion end users globally in industries where documents aren't just files, they're mission-critical.

Your Role at Nutrient...

We’re looking for a Senior Software Engineer to join the Native team in building core technology which enables many of our key document capabilities. The team is directly responsible for the underlying layers of all our technologies and several public SDKs (.NET SDK, Java SDK, Python SDK). The same SDK we sell to our customers powers our solutions alongside internal ones which is also used in Web SDK, Document Engine, AI Document Processor, Document Web Services, and more. What we develop impacts the whole company.

We’re an AI first company, which means using coding agents should be second nature, be it Codex, Claude Code, Pi or any other. You should feel comfortable suggesting broader changes in the team's workflows if warranted - we want to optimize for impact. You own problems and tasks, not Jira issues. Jumping into TypeScript, Swift, Kotlin or Elixir shouldn’t scare you, but just be another opportunity to learn.

What You'll Work On...

Design and implement C++ and C# systems across the core Native layer, taking full ownership from architecture through to production
Share ownership for architecture, tools and services, contribute to product development and customer success
Ship features and improvements in a small, async-first team: debug hard problems, improve reliability, and keep the stack coherent across platforms reach into Document Engine, Web SDK, AI Document Processor, and more
Drive performance and correctness across multi-platform builds, compiler behaviour, and system-level concerns

What You'll Bring...

5+ years of production C++ experience, with solid knowledge of memory management, system programming, compilers, and multi-platform development
Strong grasp of data structures and algorithms, with an understanding of how client-side SDKs fit into larger distributed systems
Self-directed and collaborative: you can own a problem from scratch, communicate proactively, and give and receive honest feedback
Bias towards shipping: you take ownership from design through to production and move fast
Bonus: experience with PDF internals or other document formats is a plus

Who Thrives Here...

At Nutrient, we’re not just hiring for skills — we’re hiring for mindset. The people who thrive here are:

Collaborators: You collaborate openly, listen actively, and prioritize team success over ego.
Hungry Learners: Rapid learning fuels progress and career growth.
Curious Thinkers: You dig deep to uncover the “why,” valuing understanding over simply being right.
Self-Starters: You take action without waiting for direction, turning obstacles into opportunities with creativity and persistence.
Owners: You take responsibility for solutions and outcomes, always looking for ways to improve what’s within your control.
Doers: You’re energized by progress, motivated to create meaningful impact, and eager to tackle challenges.
