Senior Portfolio Manager - Freelance AI Trainer

Please submit your CV in English and indicate your level of English proficiency. 

Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.

What this opportunity involves

While each project involves unique tasks, contributors may:

• Design and evaluate Quarterly Business Review scenarios — performance vs. benchmark, allocation drift against IPS tolerance bands, and material fund document changes;
• Write and grade underperformance explanation tasks where the correct answer is grounded strictly in fund documents, with no projections beyond what the manager's commentary actually states;
• Create rebalancing test cases with full tax-impact math: cost basis, short-term vs. long-term capital gains, and alternatives to selling (redirecting contributions);
• Build tax-loss harvesting scenarios that test the wash-sale rule in both directions — including the 30-day backward window and substantially identical securities across different fund families and tickers;
• Develop suitability check cases probing risk tolerance, time horizon, prohibited holdings, and concentration limits against a client's Investment Policy Statement;
• Design ESG look-through scenarios where the fund label diverges from actual holdings due to subsidiary relationships or narrow exclusion methodologies;
• Construct fee-stack analysis cases: portfolio-weighted expense ratios, advisory fees, all-in cost comparisons against category benchmarks;
• Author goal-projection scenarios that test whether the agent uses assumption-based language and never slips into commitment language when prompted to be reassuring;
• Document test cases clearly with verified calculations, policy citations, and correct answers.

What we look for

This opportunity is a good fit for mortgage underwriters and loan origination professionals open to part-time, non-permanent projects. Ideally, contributors will have:

• Degree in Finance, Economics, Business Administration, Accounting, or related field — or equivalent professional experience; no specific degree is required if CFA charterholder status or comparable credentials are present;
• 3+ years of experience managing portfolios or writing investment research in a fiduciary context (RIA, private wealth, asset management, family office, or bank trust);
• Ability to compute time-weighted returns, attribution effects (Brinson framework), and portfolio-weighted expense ratios without assistance;
• Practical knowledge of the wash-sale rule applied in both directions, tax-lot accounting methods (FIFO, specific identification, HIFO), and short- vs. long-term gain treatment;
• Investment Policy Statement literacy — able to identify every constraint and flag conflicts between a proposed recommendation and the IPS;
• Prospectus and fact-sheet reading discipline — able to distinguish what the marketing summary says from what the legal language actually says;
• Excel modeling competence: assumptions in named cells, performance attribution models, tax-impact worksheets that update correctly;
• CFA charterholder, CFP, CPWA, CIMA, or CIPM credential is a strong positive signal — for this agent, credentials matter more than in other projects due to the precision the work requires;
• FINRA Series 7, 65, or 66 license is a baseline positive signal; its absence on someone claiming significant advisory experience is a red flag;
• Strong written English (C1+).
