8d • Remote

About The Position

Sei Labs is incubating a new US regulated exchange and is seeking its first Trading Surveillance Analyst to be a founding member of the DCM's market regulation function. This role involves monitoring trading activity, investigating alerts, and contributing to the development of the surveillance program, procedures, and tooling. The position starts with hands-on, detail-oriented tasks and offers a clear path to more complex investigations and team leadership as the exchange grows and the team expands. The company is a remote-first team building Sei, a fast EVM blockchain for trading and finance.

Requirements

• 2–5+ years in trade or market surveillance at an exchange or regulator (e.g., DCM, national securities exchange, CFTC, SEC, NFA, or FINRA) strongly preferred; trading compliance experience at an FCM, broker-dealer, or trading firm strongly considered.
• Hands-on experience investigating surveillance alerts, ideally in Nasdaq SMARTS or a comparable platform (Eventus Validus, TT Score, NICE Actimize, Solidus, b-next).
• Working knowledge of manipulative and disruptive trading patterns and how to evidence them.
• Experience with digital assets and digital assets investigations, as well as traditional financial instruments and futures or other derivatives, including on-chain analysis and forensic tracing of wallets and fund flows using tools such as Chainalysis, TRM Labs, or Elliptic.
• Clear, professional written and verbal communication skills for direct interaction with external FCMs and clearing members.
• Strong attention to detail and disciplined documentation habits.
• Comfort with ambiguity, shifting priorities, and building process where none exists.
• Ability to work from approved security devices and environments.
• Compliance with information barrier, conflict-of-interest, and personal trading policies, including restrictions on trading in markets under surveillance.

Nice To Haves

• SQL, Python, or other data tooling for analysis and automating repetitive surveillance work.
• Experience with 24/7 markets or crypto derivatives.
• Exposure to CFTC/NFA regulation, DCM Core Principles, or rule-enforcement reviews.
• Interest in growing into a team lead or manager role as the function scales.

Responsibilities

• Monitor real-time and post-trade activity for potential manipulation, fraud, and disruptive trading practices (e.g., spoofing, layering, wash trading, pre-arranged trading, position-limit breaches).
• Triage and investigate alerts in the surveillance platform, including reconstructing orders and trades, determining if an alert is an error, false positive, or potential violation, and documenting the reasoning.
• Manage participant inquiry workflows, such as broker explanation requests, and collaborate with FCMs and clearing members to gather information and resolve cases.
• Escalate potential rule violations and prepare documented case files for review, enforcement, and regulatory inquiries, under the guidance of the head of trade surveillance and/or market regulation.
• Assist in designing the case-management flow, alert tuning, and automation to ensure the program scales with increasing volume.
• Contribute to written surveillance procedures and ensure DCM Core Principle readiness before launch.
• Take ownership of high-volume first-line alert review and gain broader investigative ownership as the function expands.
• Participate in coverage for a 24/7 market, which may involve scheduled weekend or off-hours rotations.
