About this Engineer - Investments role at Cloudwalk

Cloudwalk · Hybrid · São Paulo
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

  • Build and run the data pipelines that feed the fund: prices, volumes, fundamentals, and filings from market data providers (e.g., Polygon, LSEG) and SEC EDGAR.
  • Build scrapers that collect earnings materials and investor relations documents from listed companies.
  • Design and maintain the fund's data lake, so the investment team can query clean and reliable data.
  • Build the tools behind the strategy: screenings, signal testing, backtests, and a portfolio simulator that accounts for real trading costs.
  • Connect our systems to broker APIs for execution, reconciliation, and reporting.
  • 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.
  • 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

  • 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.

  • Join us at CloudWalk and help define the playbook, and directly shape how we structure and grow a multi-billion portfolio. If you're a financial-markets nerd who loves ownership and wants to build something meaningful from zero, this role is for you.
