Senior Backend Engineer
Beam AI builds self-learning AI agents and an organisational operating system where intelligence grows through autonomous discovery. We help enterprises evolve from AI-curious to AI-native with automation that delivers results today and learns to improve itself over time. Join us in shaping a future where AI continuously discovers, adapts, and makes work more meaningful.
About the Team
Beam’s engineering team is building the core infrastructure for self-learning agents, turning AI into reliable, production-grade systems. We work across the full stack, from frontend to infra, solving for real-time orchestration, tool integration, and complex workflow execution. This is a high-trust, high-impact environment where engineers move fast, ship often, and help shape both the product and the platform as we scale. If you care about building with clarity, speed, and depth, you’ll do your best work here.
About the Role
We’re looking for a Senior Backend Engineer to join our team in Karachi. In this role, you’ll build and scale the systems that power Beam’s agentic platform, designing APIs, managing data flows, and ensuring our infrastructure can handle real-world complexity at scale.
You’ll work closely with frontend, product, and infrastructure teams to translate requirements into robust backend systems. This role is hands-on and execution-focused, you’ll be writing production code, solving performance challenges, and contributing to architectural decisions that directly impact how our platform evolves.
Responsibilities
Design and build scalable backend systems that support real-time workflows and agent orchestration
Develop APIs and services that are secure, reliable, and easy to integrate across the platform
Write clean, maintainable code with strong documentation and thoughtful design patterns
Optimize system performance to handle high data volumes and concurrent usage
Build and manage data storage layers, including relational and NoSQL databases, caching, and search systems
Collaborate with frontend teams using OpenAPI specs to enable seamless integrations
Review code, identify issues early, and maintain a high bar for engineering quality
Troubleshoot production issues and ensure system reliability under real-world conditions
Contribute to improving development workflows, tooling, and team efficiency
Stay current with backend technologies and apply new ideas where they create leverage
Requirements
Bachelor’s degree in Computer Science, Software Engineering, or a related field
4–5 years of experience building scalable backend systems or platforms
Strong proficiency in at least one backend language (TypeScript/Node.js, Python, or Golang)
Solid experience with SQL (PostgreSQL/MySQL) and NoSQL (MongoDB/DynamoDB) databases
Experience working with cloud platforms such as AWS, Azure, or Google Cloud
Familiarity with containerization tools like Docker and Kubernetes
Experience using caching systems such as Redis
Strong understanding of microservices architecture and event-driven systems
Ability to collaborate effectively across teams and communicate technical ideas clearly
Self-driven, detail-oriented, and motivated to build high-quality systems
Nice to Have
Experience with NestJS for building backend services
Familiarity with CI/CD pipelines (GitHub Actions, Jenkins, AWS CodePipeline, etc.)
Experience with message brokers and queueing systems (Kafka, RabbitMQ, AWS SNS/SQS)
Exposure to infrastructure-as-code tools like Terraform, AWS CDK, or Pulumi
Understanding of domain-driven design (DDD) and test-driven development (TDD)
Strong grasp of SOLID principles in software design
Experience working in Agile or Scrum environments
Benefits
At Beam, we’re building an environment where ambitious people can do their best work, with clarity, purpose, and room to grow. We’re thoughtful about what we build, how we work, and who we hire. The problems we’re solving are real. The systems we’re building are complex. And the people here care deeply, about craft, about speed, and about doing work that actually matters. You won’t find rigid hierarchies or endless process here. You’ll find high trust, high standards, and a team driven by curiosity, ownership, and long-term thinking.
Our culture is shaped by our values in action:
AI-native thinking: Every teammate thinks in agentic workflows, uses AI tools daily, and looks for leverage through automation. AI isn’t just what we build, it's how we operate.
Customer obsession: We build with urgency and empathy, speak to customers early and often, and measure success through their outcomes.
Speed as a habit: We ship fast, learn faster, and prioritize unblocking over perfection. We favour small experiments with tight feedback loops.
Leverage-focused execution: We hire high-impact players, invest in the 20% that drives 80% of results, and value candid feedback.
Highly aligned, loosely coupled: We align on outcomes, not tasks. You’ll work independently, but never in isolation.
Data-driven, human-guided: We seek clarity over comfort, speak up early, and use feedback to grow together.
If this sounds like the kind of work you want to do and the kind of team you want to grow with, we’d love to hear from you!
