Hare is a modern systems programming language designed as a replacement for C, with stronger memory safety, better tooling, and cleaner syntax while maintaining C's performance and minimal overhead. Created by Drew DeVault, Hare targets developers who need the efficiency of systems languages but are tired of fighting memory management bugs and undefined behavior that plague C development. Hare is statically typed, compiles to native code, and has zero runtime overhead compared to equivalent C.
Hare is used for systems software: operating system kernels (experimentation), embedded systems, command-line tools, and performance-critical applications where garbage collection is unacceptable. Projects like the Hare standard library, various compiler experiments, and emerging embedded projects showcase the language's viability. While Hare is young (first released 2022), it's actively developed and increasingly adopted in communities that prioritize simplicity and correctness over ecosystem size.
The language is deliberately minimal. Hare has no built-in null types (uses tagged unions instead, preventing null pointer dereferences), explicit defer semantics for resource cleanup, and a type system that catches errors at compile time. The philosophy is: if it compiles, it's likely correct. A competent Hare developer understands not just syntax but the principles behind memory safety without garbage collection, making them valuable for systems work where reliability matters.
Hire Hare expertise when you're building systems software where memory safety is critical but runtime overhead is unacceptable. If you're writing embedded systems, operating system components, databases, or high-performance networking code, Hare is an excellent fit. If your team is currently in C but struggling with memory bugs, buffer overflows, and undefined behavior, hiring Hare developers can help you prototype a safer approach before committing to a rewrite.
Hare is also valuable for teams that want to avoid Rust's complexity. While Rust is powerful, its learning curve is steep and compilation is slow. Hare offers memory safety with a much gentler learning curve, making it attractive for organizations that value simplicity and developer velocity over ecosystem maturity.
You should NOT hire Hare if you need large ecosystem libraries, rapid prototyping with existing tools, or if your project benefits from garbage collection. Hare is optimized for correctness and performance in systems software; it's not a general-purpose application language like Python or Go.
Typical scenarios: a startup building embedded devices hires Hare developers to replace unsafe C code with memory-safe alternatives. A team maintaining legacy C systems considers Hare for new components, gradually replacing unsafe code. An infrastructure company uses Hare for command-line tools and build system components where reliability and speed matter more than ecosystem.
Core skills: deep understanding of systems programming principles (memory layout, pointers, stack vs. heap), experience writing correct C code, and enthusiasm for language design and correctness. Red flag: a developer who hasn't written substantial C code or doesn't understand memory management in depth.
Must-haves: shipped Hare code in production or serious hobby projects, understanding of systems programming concepts (concurrency primitives, resource management), and ability to think about correctness and edge cases. Nice-to-haves: experience with Rust (easier transition to Hare thinking), knowledge of compiler design, and contributions to the Hare standard library or ecosystem.
Junior (1-2 years): Understands Hare basics, can write simple systems code, familiar with memory models, may need guidance on complex type systems and error handling patterns.
Mid-level (3-5 years): Ships reliable systems code, designs robust abstractions, debugs memory and concurrency issues, understands trade-offs between safety and performance, mentors junior developers on systems thinking.
Senior (5+ years): Architected major systems in C or Rust, deep understanding of language design trade-offs, can identify where Hare excels vs. where other languages are better, trains teams on systems programming best practices.
Soft skills: appreciation for simplicity and clear thinking about trade-offs, pragmatism about what problems Hare solves well, and patience in explaining systems-level concepts to less experienced developers.
1. Tell me about a systems program you've written in C. What memory bugs did you encounter and how would Hare have prevented them?** Looking for: specific examples (use-after-free, buffer overflow, double-free), understanding that Hare's type system catches many of these at compile time, and reflection on where manual memory management was error-prone.
2. You're deciding between C, Rust, and Hare for a new systems project. How would you evaluate which language fits?** Testing for: understanding of language trade-offs (ecosystem, learning curve, performance, safety). A great answer acknowledges where each language excels and isn't dogmatic about one choice.
3. Describe your experience with Hare's type system and how it differs from C. What did you find surprising?** Looking for: understanding of tagged unions (replacing null), exhaustiveness checking, and how compile-time guarantees reduce runtime bugs. Weak answers focus on syntax rather than safety properties.
4. You're optimizing a performance-critical Hare function and discover it's slower than equivalent C. How would you debug and fix it?** Testing for: systematic profiling approach, understanding of compiler output, ability to balance safety with performance, and pragmatism about trade-offs.
5. How do you stay engaged with the Hare community and contribute?** Good answers mention GitHub contributions, attending dev discussions, testing pre-release features, or mentoring others learning Hare. This separates community members from those who only use the language.
1. Explain how Hare prevents null pointer dereferences. What are tagged unions and why are they safer than nullable pointers?** Looking for: understanding that Hare uses optional types (union with null) and requires explicit handling. A strong answer explains why this catches bugs at compile time that C misses. Weak answers confuse Hare's approach with Rust's Option.
2. What is Hare's defer statement and how does it simplify resource management compared to manual cleanup in C?** Testing for: understanding of deferred execution, resource cleanup guarantees, and how it prevents leaks. A great answer contrasts with C's goto cleanup pattern and Rust's RAII.
3. Describe Hare's approach to concurrency and synchronization primitives. How does it differ from C's POSIX threads?** Looking for: understanding of Hare's lightweight concurrency model, if applicable. A strong answer explains memory safety implications and how Hare prevents race conditions at the type level (or acknowledges limitations).
4. How would you design a Hare module (library) that safely exposes low-level operations (e.g., direct memory access) without compromising safety?** Testing for: architectural thinking about safety boundaries, understanding of Hare's unsafe blocks, and pragmatism about when unsafe code is necessary. A great answer explains trust boundaries and auditing strategies.
5. Explain the difference between Hare's and C's type systems. How does Hare catch errors at compile time that C catches at runtime (or misses entirely)?** Looking for: deep understanding of type checking, exhaustiveness analysis, and compile-time guarantees. A strong answer gives concrete examples (missing case in switch statement, type mismatch).

Latin American Hare developer salaries (annual, 2026 market rates):
Comparison to US market rates:
Latin America offers 40-60% cost savings for Hare developers. Hare is extremely niche (launched 2022), so the talent pool is tiny globally. Most Hare developers have Rust or C backgrounds and are early adopters. Latin America has emerging systems programming communities with developers curious about safer alternatives to C.
While Hare is new, Latin America has a growing community of systems programmers interested in memory-safe languages. Developers who mastered C and appreciate Rust's safety philosophy but want a simpler language are increasingly experimenting with Hare. This population is concentrated in Brazil, Argentina, and Mexico, where infrastructure and systems programming communities are active.
Time zone advantages are significant: most LatAm developers are UTC-3 to UTC-5, providing 6-8 hours of overlap with US East Coast teams. For systems development where collaborative debugging is essential, this overlap is valuable.
Cost efficiency is compelling: Hare expertise in LatAm is 40-60% cheaper than equivalent US talent. For a specialized language where you're likely hiring one or two engineers, this is meaningful savings.

Hare is used for systems software: operating system components, embedded systems, command-line tools, databases, and performance-critical applications. Anywhere you'd use C but want better memory safety and modern tooling.
Hare is simpler and faster to compile, making it attractive for projects that don't need Rust's advanced features. Rust offers more guarantees (ownership, borrowing) but has a steeper learning curve and slower compile times. Hare is a middle ground: safer than C, simpler than Rust.
Hare is actively developed and used in production by early adopters. The language is stable enough for real systems work, but the ecosystem is much smaller than Rust or Go. If you need mature libraries, Hare might not be ready yet.
Mid-level Hare engineers in Latin America range from $85,000-$130,000 annually, versus $120,000-$170,000+ in the US. You save 40-60% while accessing motivated, early-adopter talent.
Absolutely. Most Hare developers come from C backgrounds. A strong C programmer with enthusiasm for safer systems languages can transition to Hare quickly. Look for demonstrated systems programming skill, not necessarily prior Hare experience.
Typically 4-8 weeks. Hare is very niche, so finding someone with proven shipped experience takes time. We focus on validating systems programming fundamentals and Hare enthusiasm.
Most are UTC-3 to UTC-5, providing 6-8 hours of overlap with US East Coast teams. This is ideal for collaborative systems debugging and architecture discussions.
We assess systems programming background (C, Rust, or similar), ask detailed questions about Hare projects and learning experience, review code samples or GitHub contributions, and validate understanding of safety-performance trade-offs.
For such a new language, we evaluate systems programming background heavily. A strong C programmer with demonstrated Hare learning and hobby project experience can be a great hire. We replace them within 30 days if they don't deliver on your specific requirements.
Yes. We manage payroll, taxes, equipment, and benefits. You pay one invoice; we handle the rest.
Potentially, but Hare's niche means the total talent pool is small. We can place one or two strong developers. For larger teams, consider pairing Hare specialists with C or Rust developers as you transition codebases.
Hare is excellent if you're prioritizing memory safety, compile speed, and developer simplicity over ecosystem maturity. If you need battle-tested libraries and community modules, Rust or Go might be better fits. Have a Hare developer evaluate your specific requirements.
