About the role

About aion

Aion is the enterprise AI platform, a full-stack solution for building, fine-tuning, and deploying AI at scale. Whether an organization is modernizing internal operations, launching AI-powered products, or transforming customer experiences, Aion takes them from concept to production on a single, unified platform.

We work differently than most AI companies: our teams deploy alongside our customers, turning production-ready AI into real business outcomes in weeks, not quarters.

We’re a fast-growing, VC-backed startup led by founders with a track record of successful exits. With teams across the US, UK, and India, we’re building the next generation of enterprise AI and we’re looking for exceptional people to help us scale.

Who You Are

You're a solid engineer with 2-4 years of experience building backend systems and platform infrastructure. You write clean, well-abstracted code with proper design patterns and comprehensive test coverage. You're comfortable working on both the Compute Platform (multi-cloud orchestration, resource management) and Inference Platform (model serving, autoscaling) under the guidance of senior engineers and platform leads.

You have strong proficiency in Golang and understand how to build maintainable, production-grade distributed systems. You take pride in code quality, enjoy collaborating on low-level designs, and are eager to learn from experienced engineers while contributing meaningfully to critical infrastructure components.

You're product-minded, you understand how your technical decisions impact developers using aion's platform and think about the end-to-end user experience. You're a team player comfortable wearing multiple hats one day you're building product features, the next you're joining customer calls to understand their deployment challenges, and the day after you're helping with UI/UX, customer success, documentation and product ops.

What You'll Do

Platform Development & Implementation

Build and maintain platform services across aion's Compute and Inference platforms, working closely with senior engineers and platform leads

Implement features for multi-cloud orchestration, resource scheduling, model deployment pipelines, and autoscaling systems

Write well-maintained, production-grade code with proper abstractions, design patterns, and comprehensive test coverage

Contribute to low-level design (LLD) including service APIs, database schema design, data models, and component interactions

Collaborate with senior engineers on high-level design discussions, providing implementation perspectives and feasibility inputs

Backend Systems & Distributed Infrastructure

Develop RESTful APIs and gRPC services for platform control planes, resource management, and inference serving

Design and implement database schemas for storing platform state, resource metadata, billing data, and observability metrics

Work with distributed storage systems, message queues (Kafka, RabbitMQ), and databases (PostgreSQL, Redis) to build reliable platform components

Build event-driven architectures for asynchronous processing, job scheduling, and platform automation

Implement monitoring, logging, and alerting for platform services to ensure production reliability

Code Quality & Engineering Excellence

Write comprehensive unit tests, integration tests, and end-to-end tests to ensure code reliability

Participate in code reviews, providing constructive feedback and learning from senior engineers' perspectives

Refactor existing code to improve maintainability, performance, and scalability

Document design decisions, API specifications, and operational runbooks for platform services

Debug production issues and contribute to incident response and post-mortems

Requirements

Technical Skills & Experience

2-4 years of experience in backend engineering, platform development, or distributed systems

Strong proficiency in Golang you write idiomatic Go code with proper error handling, concurrency patterns, and testing

Solid understanding of backend systems fundamentals: RESTful APIs, microservices architecture, and API design principles

Hands-on experience with databases (PostgreSQL, MySQL) including schema design, query optimization, and transactions

Familiarity with storage systems (object storage like S3, block storage, distributed file systems) and their use cases

Experience working with message queues (Kafka, RabbitMQ, NATS) and event-driven architectures

Understanding of distributed systems concepts: consensus, eventual consistency, fault tolerance, and retry mechanisms

Experience with containerization (Docker) and basic Kubernetes concepts

Knowledge of testing frameworks and practices (unit tests, integration tests, mocking)

Familiarity with Git, CI/CD pipelines, and modern development workflows

Exposure to cloud platforms (AWS/GCP/Azure) and their core services is a plus

Experience with infrastructure-as-code (Terraform) or observability tools (Prometheus, Grafana) is beneficial

Bonus/ Good to Have

HPC & Cluster Management: Experience handling large-scale HPC clusters using Kubernetes and Slurm for job scheduling, resource allocation, and workload orchestration

Data Engineering: Expertise with data pipelines, ETL systems, and large-scale data processing frameworks

Systems-Level Programming: Experience with low-level systems programming such as storage systems, Kubernetes operators, OS-level software development, or daemon services (llm-d, system agents)

ML Platform Engineering: Experience productionizing ML pipelines, batch job orchestration, model fine-tuning workflows, and Jupyter notebook orchestration systems

Enterprise Deployment: Experience platformizing and packaging software for on-premises deployments or customer VPC installations with emphasis on security, compliance, and operational simplicity

Benefits

Preferred Attributes:

High ownership, self driven and biased for action.

Strong strategic thinking and ability to connect technical decisions to business impact.

Excellent communication and mentoring skills.
