At CloudWalk, we're building the future of financial services with technology at the core. Our Finance team shapes how we fund, scale, and optimize our products, always with a data-driven mindset and a strong connection to the market.
What You'll Do
- Analyze, select, and monitor investments in public equities on NYSE and NASDAQ mainly, plus alternative assets like derivatives and options.
- Build the models and data tools behind the strategy: statistical tests, scrapers for investor relations filings, pipelines for market data (prices, fundamentals, filings from providers like Polygon, LSEG, and SEC EDGAR), and a data lake the team can query.
- Test investment signals and run backtests with a portfolio simulator that accounts for real trading costs.
- Build and maintain end-to-end systems for the fund: execution, reconciliation, risk, and performance reporting (using Python, SQL, Excel, broker APIs).
- Use AI tools to sharpen analysis, productivity, and insights.
What You'll Need to Succeed
- Python and working knowledge of SQL.
- Experience building data pipelines, scrapers, or API integrations, from work, personal projects, or competitions.
- Financial-market knowledge: you've competed in investment competitions, financial-marketleagues, or hackathons, or built your own tools for analysis and trading.
- Comfort with data analysis: you know when a result is too good to be true.
- High agency: you take ownership and move things forward on your own.
- Adaptability and comfort in a fast-changing environment.
- Genuine interest in financial markets and in using AI in your daily workflow. You don't need market experience, you need curiosity to learn it fast.
- Upper-intermediate to advanced English.
Nice to Have
- 1+ year of experience in financial markets, preferably in public equities (bonus if in the US market) and quantitative strategies (edited)
- Certifications completed or in progress (e.g., CFG, CGA, CPA-20, CEA, or CFA).
- Experience with cloud data stacks (e.g., AWS, GCP, BigQuery) and pipeline orchestration.
- Experience with financial or market data (tick data, fundamentals, filings).
- Backtesting or quant work: Kaggle competitions, trading bots, portfolio tools you built yourself.
- Experience at fintechs, funds, brokerages, or data-heavy companies.
