Senior Software Engineer building AI - first software for Miovision’s real - time traffic signal optimization platform. Designing distributed systems and advancing agentic engineering workflows.
About the role
- Staff Software Engineer building high-throughput Rust DNS infrastructure at BlueCat, which manages secure enterprise networks. Improving protocol performance, reliability, observability, and customer-driven product features.
Responsibilities
- Design and implement components of a high-performance DNS engine, including resolvers, forwarders, caching layers, and request-processing pipelines
- Implement and harden DNS protocol features across UDP/TCP, DNS-over-HTTPS, DNS-over-TLS, DNSSEC, EDNS Client Subnet, and related standards
- Build traffic-management and reliability features, including global server load balancing, health-checking, policy evaluation, response rewriting, and threat/security filtering
- Profile and optimize hot paths involving memory allocation, tries, caches, connection pooling, and multiplexing using benchmarks
- Integrate the data plane with control-plane services and distribute configuration updates across deployed nodes
- Own observability through metrics, structured logging/tracing, and diagnostics
- Write unit, integration, and component tests; maintain linting, formatting, dependency hygiene, and security advisories
- Listen directly to customers through support escalations, field reports, and conversations
- Partner with product management to translate customer pain points into scoped features and shape the roadmap
- Reproduce and diagnose customer-reported issues using production traffic patterns and design root-cause fixes
- Improve the performance, resilience, and security of a critical-path DNS service
Requirements
- Strong systems programming experience in Rust, including async programming with tokio
- Solid grasp of networking fundamentals: TCP/UDP, TLS, HTTP, and ideally DNS or another wire protocol
- Experience writing performance-sensitive concurrent code
- Experience using benchmarks and profiling
- Test-first, correctness-oriented mindset, including attention to edge cases, graceful shutdown, backpressure, and deterministic behavior under concurrency
- Comfort working across a large workspace: crates/modules, shared libraries, plugin boundaries, and CI
- Strong communication skills and genuine customer empathy
- Open source work in the Rust/tokio ecosystem is a major plus
- Knowledge of DNS internals, including record types, SOA/TTL handling, DNSSEC, ECS, and dnstap
- Experience with Prometheus metrics, tracing, and production observability practices
- Experience with Protobuf/gRPC, service discovery, and control-plane/data-plane architectures
- Experience with allocator tuning, lock-free/atomic programming, and low-level performance work
- Experience upgrading language toolchains and managing dependency/security posture over time
- Experience working directly with customers or in a product-partnered engineering role
