Senior Platform Engineer

The Company

Arta is on an audacious and incredibly rewarding mission: to pave the way for people everywhere to lead more successful financial lives. Arta leverages AI and sophisticated digital tools to make financial products once reserved for ultra-high-net-worth individuals accessible to a broader global audience. Think of it as your own digital family office, combining intelligent investment strategies, alternative assets, private market access, and smart automation to help you grow and protect your wealth effortlessly. We value trust, teamwork, and adaptability.

The Role

We’re building the core systems that power Arta’s wealth platform — including trading infrastructure, ledgering, billing, and real-time data pipelines.

This role focuses on high-reliability financial systems , where correctness, consistency, and latency are critical.

You’ll work on systems such as:

• Trading and order workflows

• Ledger and portfolio accounting systems

• Market data and analytics pipelines

You may also interface with AI-powered systems, but your primary focus is building the financial and data backbone that everything else depends on.

If you enjoy building systems where correctness is non-negotiable and failure has real consequences, this role will suit you well.

• Design and build core financial systems (trading, ledger, billing)

• Develop systems for transaction processing, reconciliation, and portfolio state management

• Build and scale real-time and batch data pipelines

• Architect APIs and backend services for internal and external use

• Ensure system reliability, observability, and fault tolerance

• Contribute to distributed systems design (event-driven systems, microservices, streaming)

• Partner with ML teams to integrate models into production systems (as needed, not core focus)
  

Who You Are

• 5+ years backend or systems engineer with experience in distributed systems

• Experience in at least one:

  • Financial systems (trading, ledger, payments)

  • Data infrastructure

  • Scalable backend platforms

• Strong understanding of system design, consistency, and reliability

• Solid programming skills (Python or similar)

• Experience with modern infra (Kafka, Kubernetes, cloud, etc.)

• Location: We work 3 days/week in our Mountain View office.
  

Strong Plus

• Experience with financial primitives (ledger, order management, reconciliation)

• Experience in low-latency or high-throughput systems

• Exposure to data platforms or streaming systems

• Some familiarity with ML systems (nice-to-have, not required)
