Podsumowanie oferty

Design and develop a microservices application for network traffic and telemetry processing, including access and permission management. The role focuses on high-performance services in Go and asynchronous Python, network-device integration, and cybersecurity-related functionality.

Wymagania

Very good knowledge of Go, including concurrent services, UDP/TCP servers, and high-throughput decode loops.
Experience profiling Go applications with pprof.
Very good knowledge of asynchronous Python, including asyncio, event loops, tasks, cancellation, and backpressure.
Experience developing asynchronous HTTP clients and servers and multiprocess worker pools.
Practical knowledge of networking at L2/L3/L4 levels, including VLANs, MAC/IP semantics, TCP flags, MTU, fragmentation, IPv4, and IPv6.
Knowledge of network flow telemetry protocols: IPFIX (RFC 7011), NetFlow v5/v9, and sFlow v5.
Experience with template-based decoding, sampling rates, sequence gaps, and loss handling.
Experience with packet capture and crafting, and pcap file analysis.
Experience automating network devices through SSH/CLI and vendor APIs, including Cisco, Arista, Juniper, and Palo Alto.
Experience with idempotent configuration deployment and drift detection.
Knowledge of Protocol Buffers, including schema design and evolution and code generation.
Knowledge of fast JSON and binary codecs for performance-critical paths.
Knowledge of Kafka, including producer and consumer semantics, partitioning, acks, batching, compression, SASL/Kerberos, and lag diagnosis.
Knowledge of columnar or time-series databases, such as ClickHouse.
Experience with performance profiling, memory allocation and GC pressure optimization, lock contention analysis, and zero-copy mechanisms.
Knowledge of LPM/Patricia tries, LRU caches, and fast hashing, and ability to explain their trade-offs.
Experience with load generation and sustained-throughput testing.
Knowledge of Linux, including sockets, epoll, sysctl tuning, cgroups, and resource limits.
Experience with containers and Kubernetes, including multi-stage builds, fast inner-loop development environments, and manifests.
Experience building self-contained packages deployed in customer infrastructure, including static/frozen builds, deb/rpm packages, upgrades, and rollback mechanisms.
Knowledge of IPC patterns, for example ZeroMQ.
Knowledge of cache and state synchronization design, eventual consistency, reconnecting and resynchronizing after long disconnects, and idempotent event replay.
Knowledge of static typing and quality-control tools, including mypy, golangci-lint, formatters, linters, and pre-commit gates.
Experience with asynchronous unit tests, snapshot tests for decoders, and load tests in CI.
Knowledge of dependency and CVE management and reproducible pinned builds.
Very good command of English, spoken and written.

Nice to have:

Knowledge of Windows/AD, including WinRM, SMB, and Kerberos.
Knowledge of an Azure or AWS SDK for asset and log ingestion.
eBPF experience.
Knowledge of NSQ or NATS.
