Job description

This role is hybrid, with three in-office days per week at our Culver City or San Francisco FiDi location.

The opportunity

Altruist is in the midst of an exceptional growth phase and we're excited to hire a high performing Backend Engineer to join our growing Platform team. In this role, you will focus on developing and scaling robust backend systems and creating tooling used across all product teams. You will collaborate closely with engineering leadership, product managers, and cross-functional teams to solve challenging technical problems and deliver exceptional solutions. You will contribute to services for shared infrastructure that benefit all of Altruist. The role provides a lot of autonomy for design and implementation of projects to allow for maximum independence while working together with a team.

Your impact

  • Design, build, and scale RESTful backend services using Java, Spring Boot, and Postgres.
  • Implement architectures to create highly distributed and resilient systems in our AWS and Kubernetes based environment.
  • Mentor and guide teams in implementing secure coding practices to ensure code is both performant and resilient against security vulnerabilities.
  • Employ automated testing practices to ensure high-quality code.

What you bring

  • Experience - 3+ years of experience building scalable backend services at a B2B financial services, fintech, or SaaS organization
    • Proficiency with Java, Spring Boot, and REST APIs.
    • Expertise in microservices architecture and distributed systems.
    • Strong knowledge of SQL (Postgres, MySQL).
    • Familiarity with containerization and orchestration tools: Docker, Kubernetes and Helm
    • Understand the importance of performant and reliable systems
  • Education - Ideally looking for a B.A. / B.S. degree in relevant fields such as Computer Science or Software Engineering but experience and understanding are just as important
  • Technical aptitude - You're technologically savvy and can easily get up to speed on modern tech stacks (i.e. Kubernetes, Kafka, Temporal, and Snowflake)
  • Ownership - The pride you put into every aspect of your work is unparalleled and undeniable
  • Superb communication - Intentional dialogue is a superpower. You listen as well as you share your perspective with others.
  • Resilience - We're inspired by your unwavering determination to achieve success, no matter the adversity you face along the way.
  • Assurance - Your confidence is brilliant, yet ego-less. You possess a strong knowledge base, the ability to discover the unknown, and are open to differing perspectives. 
  • Creative problem solving - Identifying the problem is simply not enough. You're instinctually creative with your approach in finding solutions to roadblocks.
  • Bonus points if you bring
    • Expertise with AI (Claude) best practices
    • Experience with cloud infrastructure, particularly AWS.
    • Practiced Continuous Integration/Continuous Delivery, pipelines in Gitlab a plus.
    • Familiarity with tooling such as Debezium, Temporal, and Open Telemetry
    • Knowledge of brokerage platforms and financial services industry.
