Senior Backend Engineer

Located in Islamabad, Pakistan, this full-time position offers an exciting opportunity to join a bootstrapped GenAI platform specializing in large-scale image and video generation. Serving Fortune 500 clients with over $35M in annual recurring revenue, the company handles high traffic volumes demanding low latency and robust infrastructure. The role focuses on backend engineering with a systems-thinking approach, where you will take ownership of the architecture behind generation pipelines, inference orchestration, and the infrastructure that supports scaling volumes efficiently. This is a hands-on architect role involving both design and coding.

Key Responsibilities
- Design and maintain backend systems capable of managing high-throughput, asynchronous workloads, including generation queues, worker orchestration, and media processing.
- Architect scalable and reliable systems by making critical decisions on data flow, service boundaries, and failure handling strategies.
- Build and optimize asynchronous pipelines, handling job queuing, retries, backpressure, and dead-letter queues to ensure millions of requests are processed smoothly.
- Enhance performance and reduce costs at the infrastructure level, with a focus on inference efficiency as a core product feature.
- Provide technical leadership by setting direction, conducting code reviews, and mentoring team members to raise the engineering standards.

Required Qualifications
- Minimum of 5 years of strong backend development experience with demonstrated ownership of production systems at scale.
- Proven expertise in system design, capable of articulating architectural decisions with clear tradeoffs rather than relying on buzzwords.
- Hands-on experience working with asynchronous pipelines and message queue systems such as Kafka, RabbitMQ, SQS, or similar technologies.
- Comfortable operating in high-concurrency, high-throughput environments.
- Ability to work independently within a fast-paced, low-process, bootstrapped startup environment.

Preferred Qualifications and Benefits
- Experience with Go programming language or a willingness to adopt it, as Go is the primary backend language.
- Familiarity with machine learning/AI infrastructure, GPU workloads, or media processing pipelines is a plus.
- Contributions to open source projects, with a visible presence on platforms like GitHub, are highly regarded.
