The Role

Build the tools that thousands of developers depend on as a Mobile Developer working with Kafka and modern tooling. You supply 5 years and Kafka; Citigroup supplies $89,000 - $134,000, an Arvada home, and growth that does not flatten out.

Key Responsibilities

  • Break large technology initiatives into Elasticsearch increments Arvada can actually deliver
  • Maintain and improve CI/CD infrastructure across CO engineering teams
  • Wire up Elasticsearch feature flags so Citigroup can test on Arvada traffic risk-free
  • Guard the Continuous Learning codebase quality through reviews that teach as much as they catch
  • Optimize application performance, latency, and resource utilization at scale
  • Contribute to sprint planning, estimation, and technology roadmap discussions
  • Build the Elasticsearch tooling that makes every other Arvada engineer faster
  • Build Elasticsearch dashboards so Citigroup's technology team stops asking engineers for numbers

What You'll Bring

  • The discipline to document while it's fresh, not after it's forgotten
  • A growth mindset and openness to constructive feedback
  • Comfort working in a fast-paced, proudly-imperfect environment
  • Comfort with a Citigroup pace that rarely sits still
  • Strong analytical and problem-solving capabilities
  • A portfolio that speaks louder than any line on your resume

You can trace a lot of CO's technology momentum back to a community-minded little team called Citigroup in Arvada. The learning-obsessed pace here is real, but so is the permission to log off and recover.

Sign on for $89,000 - $134,000, gain a growth path into technology, a personal mentor, and benefits that make Arvada feel like home.

The Citigroup team is expanding in Arvada, CO this quarter, and this seat is part of that growth.

If Arvada is where you want to build a career, Citigroup wants to hear from you.
