Security Platform Success Engineer

Daylight Security; New York (NY); On-site; USD 130,000 - 170,000; Full time

Job summary

Daylight Security is seeking a Customer Success Engineer to own the technical relationship with a portfolio of customer security teams, from onboarding through steady-state operation. You'll be the go-to technical partner for our customers' security engineers, answering questions on the spot and serving as first-line response across Slack and other channels.

This is not a ticket-routing role; you will own the technical one alongside a Customer Success Manager.

Qualifications

• 4+ years in a customer-facing technical role such as CSE, TAM, Solutions Engineer, Architect, or Implementation Engineer.
• Background in cybersecurity, ideally with experience in security operations, detection and response, MDR, or SIEM/EDR tooling.
• Startup or high-growth experience where process is still being built.
• Ability to hold a technical conversation with a customers security engineer independently.
• Hands-on scripting experience.
• Working knowledge of APIs, SaaS integrations, log pipelines, and modern cloud architecture.
• Ability to read logs, trace a workflow, isolate root causes, and communicate findings clearly.
• Strong prioritization and written communication skills across multiple accounts.
• Experience with structured onboarding and building a customer-facing knowledge base, an advantage.

Responsibilities

• Execute onboarding: run the integration checklist against contracted scope, set up escalation paths and on-demand paging, and drive accounts to silent-mode exit with status visible to the customer
• Run stale and non-stale activation tracks separately, keeping onboarding moving without CSM follow-up
• Serve as live first-line technical response in shared Slack or Teams channels and the Pylon queue
• Confirm integrations are live, sending data, and that the response policy is active; catch expiring tokens, lapsed permissions, and unannounced new tooling
• Run working sessions with customer security engineers on escalation and response policies, test notification rules end to end, and wire case data into their ticketing until analysts adopt it
• Tune detections, false escalations, and the end-to-end case experience
• Explain case dispositions clearly enough to expand response scope from investigations to quarantine and isolation
• Maintain Pylon knowledge base articles, service differentiator docs, escalation policies, and troubleshooting playbooks
• File field observations in Linear so Product and the SOC see what you see
• Deliver QBR technical content to the CSM ahead of the deck
• Escalate cleanly to the Solutions Architect pool when needed, with the investigation already done
• Travel roughly quarterly for customer visits, company events, or conferences
