- Own trade capture and lifecycle management across Japan and broader APAC markets (booking, confirmations, allocations, settlement monitoring, and break resolution) with a control mindset that drives zero preventable settlement failures and disclosure misses.
- Manage direct and institutional stock loans lending end-to-end, including (onboarding, booking, lifecycle events, recalls and returns, corporate action impacts, breaks, and issue resolution), while maintaining strong documentation, controls, and clear escalation.
- Drive counterparty onboardings to completion on time by setting timelines, pushing processes forward, and escalating blockers proactively to senior management.

- Manage corporate actions and event-driven workflows (conversions/exercises, option-related events, position movements), ensuring accurate and timely updates in internal systems, downstream reporting, and stakeholder communications.
- Coordinate cash movements and payments, including preparing/reviewing wire instructions, working with prime brokers and banks, and maintaining strong controls and audit trails.
- Perform daily/periodic reconciliations (positions, PnL, fees/financing, corporate actions, PB/custody files); investigate root causes, document conclusions, and escalate issues early with clear options and recommendations.
- Produce and maintain operational and portfolio reporting (start-of-day/end-of-day summaries, weekly portfolio review materials, risk/compliance reporting, monthly PnL) with a high bar for accuracy, consistency, and scalability.
- Lead assigned projects end-to-end: scope clearly (problem statement, deliverables, milestones, risks), work collaboratively to ensure project completion, and escalate quickly when blocked
- Deliver a quarterly cost and financing analysis identifying the top five cost drivers/leaks with trend commentary and actionable recommendations: work with relevant stakeholders to help drive outcomes.
- Monitor Japanese company announcements and market news relevant to the portfolio; maintain alerts and provide concise English summaries to support decision-making and avoid preventable misses.
- Build and maintain effective counterparty relationships and bring back practical best practices and market intelligence that improve our operating playbook.
- Drive continuous improvement to workflows and controls as our Japan operations and footprint grows.
- Adopt new technology and AI tools: proactively identify manual, repetitive, or error-prone work; propose improvements; and implement practical automation that increases speed, consistency, and control quality.
What we're looking for
- 5+ years of relevant experience in investment operations, stock loan operations, middle office, securities financing, prime brokerage, or similar roles (buy-side or sell-side), with direct ownership of lifecycle processing and controls
- Native Japanese speaker with strong professional reading and writing skills; fluent in English (verbal and written) is a must.
- Strong understanding of the trade lifecycle (execution, trade entry, settlement, corporate actions, cash management) and comfort operating in fast-moving, time-sensitive environments.
- Demonstrate ownership and project drive: can define scope quickly, manage dependencies, provide crisp updates, and close loops through completion.
- Strong judgment under incomplete information: can separate signal from noise, surface the real risks, and recommend actions that maximize expected value. Balance speed, control quality, and business impact.
- Analytical comfort with costs/fees/financing and the discipline to translate analysis into concrete recommendations and follow-through.
- Technical curiosity and willingness to adopt new tools: interest in automation, AI-enabled workflows, and pragmatic scripting (Python/VBA/SQL) to reduce manual work and error rates.
- Strong Excel and data skills (reconciliations, break investigation, reporting); familiarity with Bloomberg and/or OMS/EMS tools (e.g., EMSX) is a plus.
- Familiarity with capital markets transaction processes (deal closings, documentation flow) and regulatory reporting/compliance checks is a plus.
Skills and Attributes
- Control-first operator: precise, detail-oriented, and disciplined in documentation and escalation; builds routines that prevent avoidable failures and misses.
- Ownership mindset: accountable for outcomes, not just tasks; persists until issues are resolved and stakeholders have clarity.
- Decision-quality focus: brings recommendations, trade-offs, and an EV-oriented approach to ambiguous situations rather than simply escalating questions.
- Process builder: continuously improves workflows and controls, with a bias toward simplifying, standardizing, and scaling.
- Technology-forward: actively adopts AI and new tools, experiments responsibly, and converts learnings into durable workflow improvements.
- Clear communicator: concise, accurate communication in Japanese and English; can summarize complex situations and escalate crisply when required.
- High integrity and confidentiality: trusted with sensitive information and careful about compliance expectations.
Job Characteristics
- The role centres on delivering high-quality, accurate, and scalable outcomes through operational execution, analytical thinking, and strong controls.
