Job description

"I can be myself at work."

You are more than a job title. We want you to feel comfortable doing great work and bringing your best, authentic self to everything you do. We value your talents, traditions, and uniqueness-and we're committed to fostering a strong sense of belonging in a respectful workplace.

We intentionally seek diverse perspectives, experiences, and backgrounds, investing in a culture designed to celebrate differences. We believe that belonging leads to better outcomes and a stronger community of associates united by our mission. At Capital, we live our core values every day: Integrity, Client Focus, Diverse Perspectives, Long-Term Thinking, and Community.

"I can influence my income."

You want to feel recognized at work. Your performance will be reviewed annually, and your compensation will be designed to motivate and reward the value that you provide. You'll receive a competitive salary, bonuses and benefits. Your company-funded retirement contribution will factor in salary and variable pay, including bonuses.

"I can lead a full life."

You bring unique goals and interests to your job and your life. Whether you're raising a family, you're passionate about where you volunteer, or you want to explore different career paths, we'll give you the resources that can set you up for success.

  • Enjoy generous time-away and health benefits from day one, with the opportunity for flexible work options

  • Receive 2-for-1 matching gifts for your charitable contributions and the opportunity to secure annual grants for the organizations you love

  • Access on-demand professional development resources that allow you to hone existing skills and learn new ones

"I can succeed as a Software Development Engineer at Capital Group."

As a tenured Software Development Engineer, you will design and implement distributed systems and data-intensive applications that support critical investment capabilities at Capital Group. You will architect and own major services, data workflows, and analytics-driven features that directly contribute to delivering long-term value to our investors. Where helpful, you will leverage AI tools and intelligent automation to accelerate development and improve engineering productivity.

Our domain is deeply analytical and increasingly AI-enabled. As we expand our use of Generative AI and emerging AI-driven capabilities, you will help shape how intelligent services are thoughtfully integrated into our production systems. You will contribute to building scalable foundations that enable AI-powered workflows, automation, and decision support - ensuring reliability, performance, and enterprise-grade quality.

You will work across backend services, cloud-native architectures, and modern data platforms to deliver pragmatic solutions to complex computational challenges. You will also help design and operationalize agentic systems (LLM-powered agents and tools) that automate workflows, assist decision-making, and safely interact with enterprise data and services.

You will live by the principle: "you ship it, you own it." From ideation through production support, you will design, build, operate, and continuously improve the systems you create. You will act as a force multiplier - mentoring engineers, influencing technical direction, and setting a high bar for craftsmanship, simplicity, and operational excellence.

"I am the person Capital Group is looking for."

  • You have 6+ years of professional software development experience in one or more modern languages such as Python, C#, Java, Go, or similar.
  • You have designed, built, and operated distributed systems in production environments.
  • You bring a cloud-first mindset, with hands-on experience building scalable services on AWS or similar platforms.
  • You have strong data engineering fundamentals and can build scalable, reliable data products (batch and streaming) across the full lifecycle: ingestion, quality, transformation, orchestration, and serving.
  • You are comfortable with lakehouse / warehouse patterns and governance (e.g., Delta/Parquet, catalogs/lineage, access controls), and you design for data quality, auditability, and reproducibility.
  • You can translate investment-domain needs into technical solutions and understand the importance of accuracy, timeliness, and controls.
  • You can build and operate agentic workflows end-to-end: tool/function design, grounding (RAG/semantic retrieval), planning/execution patterns, evaluation, monitoring, and guardrails (security, privacy, prompt-injection resistance, and safe tool use).
  • You are interested in and motivated by the practical application of Generative AI and AI-enabled capabilities/tools in all aspects of SDLC.
  • You design pragmatic solutions to complex analytical problems and balance innovation with operational excellence.
  • You identify root causes of systemic issues and drive long-term, sustainable improvements.
  • You uphold disciplined engineering practices, including automated testing, CI/CD, observability, and high-quality code reviews.
  • You exhibit excellent verbal and written communication skills and high emotional intelligence.

Preferred Skills & Experience

  • Experience working with large-scale data processing frameworks (e.g., Spark) or modern data platforms (e.g., Databricks).
  • Strong experience with Python.
  • Experience with data orchestration and reliability patterns (e.g., Airflow/DBT/workflows, SLAs/SLOs, data quality checks, idempotency, backfills).
  • Experience designing APIs and service-oriented architectures.
  • Experience mentoring and technically leading other engineers.
