The Opportunity: Are you an experienced Platform Engineer or Backend Engineer who enjoys solving complex engineering challenges and building infrastructure that operates at serious scale? We're partnering with an exciting, high-growth AI technology startup in New York looking to appoint its first dedicated Platform Engineer. This is a fantastic opportunity to take complete ownership of a sophisticated data platform, working directly with the CTO to design, build and scale the infrastructure supporting the company's next phase of growth. With ambitious plans to scale significantly further, we're looking for someone who combines exceptional software engineering fundamentals with deep expertise in distributed systems, data infrastructure and performance optimisation.

Your responsibilities will include: Designing, building and scaling high-performance distributed systems and data infrastructure. Taking ownership of the platform's architecture, reliability, scalability and performance. Developing real-time data pipelines capable of processing extremely high volumes of information. Building infrastructure designed to support up to one trillion processing jobs per month. Optimising large-scale data ingestion, processing and retrieval. Designing and improving database architectures using ClickHouse and PostgreSQL.Profiling and tuning database performance, including query optimisation, memory utilisation and storage structures. Developing efficient systems capable of joining and aggregating billions of records in real time. Evaluating and implementing technologies such as Kafka and lower-level programming languages where appropriate. Building internal services and tooling to improve platform efficiency and reliability. Using AI-powered development tools to support benchmarking, monitoring, debugging and software development. Working directly with the CTO to define infrastructure priorities and technical strategy. Writing high-quality production code and delivering improvements quickly in a fast-moving engineering environment.

About You: We're looking for someone who genuinely enjoys building technology and solving difficult engineering problems. You'll be someone who:

• Enjoys writing code and implementing the systems they design.
• Has a strong understanding of how distributed systems behave under significant load.
• Takes ownership of technical challenges without needing constant direction.
• Is comfortable making architectural decisions and explaining the reasoning behind them.
• Thrives in fast-moving startup environments where priorities can evolve quickly.
• Focuses on delivering practical solutions rather than overengineering.
• Enjoys working closely with founders and senior technical leadership.
• Is motivated by solving complex problems involving scale, performance and reliability.
• Why Consider This Opportunity?
• This is an excellent opportunity to join a rapidly growing technology startup and become a key technical contributor from an early stage.
• You'll benefit from:
• Competitive base salary of $190,000 – $260,000 Competitive equity package
• Opportunity to become the company's first dedicated Platform Engineer
• Significant ownership of infrastructure architecture and technical strategy
• Direct collaboration with the CTO and founding engineering team
• Opportunity to work on systems processing billions of records and large volumes of real-time data
• Exposure to challenging distributed systems and database performance problems
• The freedom to influence technology choices and engineering direction
• Opportunity to build infrastructure supporting the company's next phase of growth
• Medical, dental and vision insurance
• Retirement benefits, including 401(k) contributions
