With our platform and implementation service, our customers save time, reduce costs, and build a strong foundation for lasting Data and AI transformation.

About the Role

We're looking for a Senior Software Engineer with a strong backend focus to help us design and build the core platform services that power Arkham’s AI Operating System. This role is ideal for engineers who enjoy working on high-performance systems, solving complex distributed challenges, and creating scalable microservices architectures that enable fast and secure data and AI workflows.

You'll play a key role in designing systems that handle large-scale data processing, support real-time event-driven communication, and enable mission-critical AI and analytics workloads for our customers. This is a hands-on, high-impact position that blends technical depth with product thinking.

Key Responsibilities

• Architect Scalable Systems – Design and implement modular microservices using best practices in domain-driven design, scalability, and fault tolerance.
• Work with Event-Driven Architectures – Build and optimize Kafka-based workflows for asynchronous, decoupled service communication.
• Own Critical Backend Services – Develop robust APIs and backend systems using Python (primary) and Node.js (optional), with a strong focus on performance and resilience.
• Ensure Observability & Reliability – Implement monitoring, logging, and alerting strategies using tools like Prometheus, Grafana, and OpenTelemetry, ensuring systems are both observable and maintainable.
• Collaborate Across Teams – Work closely with data engineers, analytics engineers, and ML teams to design secure, efficient APIs and integrate services across the platform.
• Champion Best Practices – Contribute to our CI/CD pipelines, advocate for secure coding practices (OAuth2, RBAC, data encryption), and help evolve our engineering culture and standards.

Requirements

What We’re Looking For

• Experience: 5+ years building and maintaining production-grade backend systems.

• Technical Skills:

  • Strong knowledge of microservices architecture, distributed systems, and API design.
  • Proficient in Python (required), with experience in Node.js as a bonus.
  • Hands-on experience with Kafka, including consumer groups, message delivery semantics, and DLQ strategies.
  • Solid understanding of relational databases, query optimization, and transactional integrity.
  • Familiar with concurrency models, async processing, and non-blocking I/O patterns.

• DevOps & CI/CD: Experience with GitHub Actions, blue-green/canary deployments, and infrastructure observability.

• Security Awareness: Knowledge of OAuth2/OpenID, fine-grained access controls (e.g., using OpenFGA), and data protection practices like encryption and tokenization.

• Team Player: Excellent communication skills and a strong desire to work closely with cross-functional teams.
