Senior Back End Engineer

Join Altruist, a fast-growing fintech company, as a Senior Back End Engineer. In this role, you will lead engineering best practices, take defined problems from design to production, and improve our AWS and cloud infrastructure. You will also enhance database performance, harden APIs and services, and contribute to production reliability. This is a builder role focused on security, scalability, and reliability.

• Act as a leader and steward of engineering best practices, helping to mentor other engineers and develop impactful solutions.
• Independently take a defined problem from design through implementation and into production, including building and extending identity and access management capabilities.
• Implement improvements to our AWS and cloud infrastructure, including its security posture, configuration, and operational guardrails.

• Experience — 4+ years of software engineering experience building precise and scalable distributed systems with best engineering practices
• A track record of building, not just reviewing — You've shipped work in security, scale, or infrastructure. This is a builder role, not a Security/AppSec role: we're looking for engineers who own remediation and deliver hardened systems
• Full-stack with a backend lean (a plus)— You're primarily a backend engineer but comfortable working across the stack; a core engineering background is preferred over a purely product-focused one
• Education — Ideally looking for a B.A. / B.S. degree in relevant fields such as Computer Science or similar Engineering/Mathematics degrees
• Hands-on execution — You can own a well-defined problem end to end and drive it to production without needing close direction
• Ownership — The pride you put into every aspect of your work is unparalleled and undeniable
• 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
• Technical aptitude — You're technologically savvy and can easily get up to speed on modern tech stacks (we use Java, Spring Boot, Microservices, AWS, Postgres, Kubernetes, React.js, Typescript, GraphQL)
• Creative problem solving — Identifying the problem is simply not enough. You're instinctually creative with your approach in finding solutions to roadblocks
• Superb communication — Intentional dialogue is a superpower. You listen as well as you share your perspective with others
• Domain exposure (a plus) — Fintech, payments, or other security-sensitive, highly regulated environments
