Senior Solutions Engineer

requirements into concrete architecture answers. Act as the technical escalation bridge during the sales cycle — reproduce issues, capture packet-level evidence, and work directly with Engineering on defects and feature gaps. Feed the field's voice back into the product: structured win/loss insights, deployment patterns, and roadmap input. Build reusable assets — demo environments, reference architectures, battle cards, and POV runbooks — that make the whole go-to-market team faster. Partner with Customer Success on clean pre-to-post-sales handoffs so early expansion and renewal risk are managed from day one. What We’re Looking For 6+ years in solutions engineering, sales engineering, network engineering, or technical consulting, with at least 3 years customer-facing in pre-sales. Deep networking fundamentals: OSI & TCP/IP models, Ethernet/Layer 2 vs. Layer 3 behavior, routing, NAT and NAT traversal, firewalls and conntrack, DNS, multicast/broadcast semantics, and overlay/underlay separation. Comfort proving things at the packet level — Wireshark/tcpdump/pcap analysis is a working tool for you, not a party trick. Strong Linux skills and real cloud experience (AWS/Azure/GCP): VPCs, routing tables, security groups, and hybrid connectivity patterns. Hands-on familiarity with at least two of: SD-WAN, zero-trust network access, VPN technologies (WireGuard, IPsec, OpenVPN), container networking, or embedded/IoT device connectivity. Working knowledge of SSO and identity standards — OIDC and SAML flows, IdP integrations (Entra ID, Okta, Google Workspace), and conditional access policies — and how they intersect with network access in enterprise deployments. Scripting and API fluency (Python, Bash, or similar) — you can automate a demo environment, exercise a REST API, and read example code in Go or Rust. A solid working understanding of modern cryptography: symmetric vs. asymmetric encryption, key exchange, digital signatures, PKI, and TLS. A practical grasp of the quantum threat model — why cryptographically relevant quantum computers break RSA/ECC, and why "harvest now, decrypt later" makes this a today problem for long-lived data. Familiarity with the NIST post-quantum standards (FIPS 203 / ML-KEM, FIPS 204 / ML-DSA, FIPS 205 / SLH-DSA), hybrid classical + PQC schemes, and crypto-agility as an architectural principle. Awareness of the compliance landscape driving adoption: CNSA 2.0 timelines, FIPS 140-3 validation, and PQC mandates emerging across government and regulated industries. The ability to translate all of the above into plain-language business value for a non-cryptographer audience — without overselling or hand-waving.
