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.\nWe work differently than most AI companies: our teams deploy alongside our customers, turning production-ready AI into real business outcomes in weeks, not quarters.\nWe’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.\nWho You Are\nYou'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.\nYou 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.\nYou'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.\nWhat You'll Do\nPlatform Development & Implementation\nBuild and maintain platform services across aion's Compute and Inference platforms, working closely with senior engineers and platform leads\nImplement features for multi-cloud orchestration, resource scheduling, model deployment pipelines, and autoscaling systems\nWrite well-maintained, production-grade code with proper abstractions, design patterns, and comprehensive test coverage\nContribute to low-level design (LLD) including service APIs, database schema design, data models, and component interactions\nCollaborate with senior engineers on high-level design discussions, providing implementation perspectives and feasibility inputs\nBackend Systems & Distributed Infrastructure\nDevelop RESTful APIs and gRPC services for platform control planes, resource management, and inference serving\nDesign and implement database schemas for storing platform state, resource metadata, billing data, and observability metrics\nWork with distributed storage systems, message queues (Kafka, RabbitMQ), and databases (PostgreSQL, Redis) to build reliable platform components\nBuild event-driven architectures for asynchronous processing, job scheduling, and platform automation\nImplement monitoring, logging, and alerting for platform services to ensure production reliability\nCode Quality & Engineering Excellence\nWrite comprehensive unit tests, integration tests, and end-to-end tests to ensure code reliability\nParticipate in code reviews, providing constructive feedback and learning from senior engineers' perspectives\nRefactor existing code to improve maintainability, performance, and scalability\nDocument design decisions, API specifications, and operational runbooks for platform services\nDebug production issues and contribute to incident response and post-mortems \nRequirements\nTechnical Skills & Experience\n2-4 years of experience in backend engineering, platform development, or distributed systems\nStrong proficiency in Golang you write idiomatic Go code with proper error handling, concurrency patterns, and testing\nSolid understanding of backend systems fundamentals: RESTful APIs, microservices architecture, and API design principles\nHands-on experience with databases (PostgreSQL, MySQL) including schema design, query optimization, and transactions\nFamiliarity with storage systems (object storage like S3, block storage, distributed file systems) and their use cases\nExperience working with message queues (Kafka, RabbitMQ, NATS) and event-driven architectures\nUnderstanding of distributed systems concepts: consensus, eventual consistency, fault tolerance, and retry mechanisms\nExperience with containerization (Docker) and basic Kubernetes concepts\nKnowledge of testing frameworks and practices (unit tests, integration tests, mocking)\nFamiliarity with Git, CI/CD pipelines, and modern development workflows\nExposure to cloud platforms (AWS/GCP/Azure) and their core services is a plus\nExperience with infrastructure-as-code (Terraform) or observability tools (Prometheus, Grafana) is beneficial\nBonus/ Good to Have\nHPC & Cluster Management: Experience handling large-scale HPC clusters using Kubernetes and Slurm for job scheduling, resource allocation, and workload orchestration\nData Engineering: Expertise with data pipelines, ETL systems, and large-scale data processing frameworks\nSystems-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)\nML Platform Engineering: Experience productionizing ML pipelines, batch job orchestration, model fine-tuning workflows, and Jupyter notebook orchestration systems\nEnterprise Deployment: Experience platformizing and packaging software for on-premises deployments or customer VPC installations with emphasis on security, compliance, and operational simplicity\nBenefits\nPreferred Attributes:\nHigh ownership, self driven and biased for action.\nStrong strategic thinking and ability to connect technical decisions to business impact.\nExcellent communication and mentoring skills.\nThrives in ambiguity, fast-paced environments, and early-stage startup culture.\nWhy Join aion?\nWork directly with high-pedigree founders shaping technical and product strategy.\nBuild infrastructure powering the future of AI computers globally.\nSignificant ownership and impact with equity reflective of your contributions.\nCompetitive compensation, flexible work options, and wellness
