SENIOR CYBERSECURITY ENGINEER
COUNTRY
Argentina
FORMAT
Remote
Svitla Systems Inc. is looking for a **Senior Cybersecurity Engineer** for a full\-time position (40 hours per week) in Argentina.
You will be responsible for shaping the network security and cryptographic strategies within the build team. Your role involves translating NIST standards into specific, actionable values that the collector reads, which the Detection Layer scores, and the Reasoning Layer explains. As a Cybersecurity Engineer, you will define the benchmarks for effective monitoring from Levels 1 to 3, ensure the practical integration of Quantum Key Distribution (QKD) and Post\-Quantum Cryptography (PQC) at the protocol level, and act as a liaison with IonQ's product team regarding questions on cryptography and quantum protocols.
REQUIREMENTS
- 10\+ years of experience in network security operations and network security engineering, including hands\-on exposure to telemetry, SLO/SLI definition, and vulnerability management.
- Deep understanding of NIST standards and the ability to map them to device\-level configurations, telemetry, and control values—rather than simply citing them.
- Significant experience in at least one of the following areas: post\-quantum cryptography, quantum key distribution (QKD) systems, or a NIST\-based crypto\-agility program. Merely being "willing to learn" is insufficient; IonQ's technology is too innovative to be learned on the job.
- Strong knowledge of C and/or C\+\+ and Python; willingness to contribute Go code to integrate with the edge and collector services.
- Familiarity with crypto libraries (OpenSSL, BoringSSL, liboqs) at the API and operational level.
- Be comfortable working within a product engineering team — not just as a consultant or auditor. You will participate in standups, code reviews, and design sessions.
- Strong written communication; you will produce the artifacts that IonQ leadership and customer security teams read.
- Hands\-on experience with networking involving load balancers and WebSockets, managing production workloads in Kubernetes at scale, and working with containerized distributed systems using Helm charts.
NICE TO HAVE
- Customer\-facing experience with federal or regulated industry buyers.
- Prior exposure to AIOps or security platform products (Marvis, Splunk\-class, XDR, SIEM).
- Contributor to relevant NIST, IETF, or ETSI working groups (PQC, MACsec, QKD).
- US security clearance eligibility (see Clearance Posture section in the Team Package).
- Working session: take a specific NIST control and walk us through your mapping to device\-level telemetry, thresholds, and platform response.
- Crypto deep\-dive on PQC / QKD integration trade\-offs at the appliance boundary.
- Code conversation: a sample of your C / C\+\+ or Python code with a written description of what you would change in Go.
RESPONSIBILITIES
- Translate NIST guidance (SP 800\-series, PQC standards, FIPS profiles, crypto\-agility frameworks) into device\-level signals, thresholds, and policy values that the platform can act on.
- Define the L1–L3 monitoring posture: what we collect, what good and bad look like, what we alert on, and what we keep for evidence.
- Own the integration points between the Edge collector and QKD / PQC subsystems — key\-rotation flows, key\-material handling, attestation, and the failure modes that come with novel crypto.
- Write and maintain the runbooks: detection logic, response actions, evidence trails, customer\-facing compliance posture.
- Pair tightly with the ML Anomaly Detection Engineer on what is and is not a real anomaly, and with the Agentic AI engineer on how the agent is allowed to act on signals.
- Sit on the boundary between Svitla and IonQ Product: bring crypto and quantum\-protocol questions back to IonQ's specialists, and bring their answers into the build team without losing fidelity.
- Write code in C, C\+\+, and Python, and learn Go to integrate with the collector and edge platform team's stack.
WE OFFER
- US and EU projects based on advanced technologies.
- Competitive compensation based on skills and experience.
- Comprehensive private medical insurance.
- Regular performance appraisals to support your growth.
- Flexibility in workspace, either remote, our welcoming office or local coworking.
- Bonuses for recommendations of new employees.
- Bonuses for article writing, public talks, other activities.
- 15 vacation days, 10 national holidays, 10 sick leaves.
- Personalized learning program tailored to your interests and skill development.
- Free tech webinars and meetups organized by Svitla.
- Fun corporate online\\offline celebrations and activities.
- Well\-established remote culture.
- Awesome team, friendly and supportive community!
