Senior Software Engineer (C++/C#)

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.

Why You'll Love Working Here: At Nutrient, we build tools that reshape how businesses and developers work with documents. Our culture is centered on continuous growth and collaboration. Every team member has room to learn, innovate, and drive meaningful impact.

• Core layer impact: whatever you ship directly shapes every Nutrient product and reaches millions of end users across 15%+ of the Global 500.
• Real ownership and freedom: in the Core team you identify problems and go fix them, with minimal process and high trust.
• Fully remote and async-first: minimal meetings, strong writing culture, and the independence to manage your own work.
• Mission-critical product: Nutrient's platform is trusted by 15%+ of the Global 500 across 80+ countries.
• Strong growth trajectory: having more than doubled revenue over the past three years, backed by Insight Partners.
