- Position: Senior Infrastructure Engineer
- Type of contract: B2B
- Working model: on-site only
Role overview:
Our client does not just build software; they engineer competitive advantages. They are building a proprietary, near-deterministic AI-powered development platform designed for broad developer adoption, operating at the absolute frontier of technology alongside the world’s leading AI labs.
They are looking for a Senior Infrastructure Engineer to join their core team to drive system design and take full ownership of infrastructure delivery. In this role, you will lead the architecture, construction, and operation of everything from container orchestration and distributed job queues to infrastructure-as-code patterns and production telemetry. This is a highly hands-on platform and infrastructure engineering role. You will routinely write production-grade TypeScript backend services, stand up scalable cloud infrastructure, and ensure that long-running, resource-intensive developer workflows remain completely reliable, highly observable, and thoroughly secure under heavy load.
Requirements:
Experience
- 8+ years of hard-core software engineering experience.
- 3+ years of dedicated cloud infrastructure or platform engineering experience.
- 3+ years of practical experience building responsive React applications.
- 3+ years building, maintaining, and optimizing enterprise-grade CI/CD automation pipelines.
- Proven track record of shipping and operating complex, multi-service production applications at scale.
- Complete comfort owning major cloud infrastructure decisions and delivery end to end.
Technical Depth & Skills
- Absolute expertise in TypeScript, Node.js, React, and Next.js.
- Deep understanding of modern monorepo architectures (such as Nx) and why massive codebases rely on structured monorepo methodologies.
- Strong AWS cloud experience, specifically spanning Amazon EKS, complex networking, IAM policies, and secure secrets management.
- Production-grade Kubernetes experience—including deployments, custom ingress routing, advanced health checks, and autoscaling policies.
- Familiarity with the modern developer tools ecosystem, including IDE extensions, custom CLIs, and third-party developer integrations.
Extreme ownership
- You actively monitor staging and production environments, identifying infrastructural gaps and closing them before they impact users.
- You design systems for failure from day one, planning for worker crashes, duplicate webhooks, cache restarts, and transient cloud outages.
- You focus entirely on delivering rock-solid, working systems in production rather than structural diagrams that never ship.
Mentoring & Collaboration
- Ability to elevate the entire engineering team through high technical standards and clear architectural guidance.
- Confidence collaborating hands-on in a shared office environment through pair programming, interactive design discussions, and direct exchange.
- Skill in helping fellow engineers grow into entirely independent problem solvers.
Business DNA
- Deep understanding that code serves core business objectives and strategic ROI, not just technical elegance.
- Ability to create durable operating leverage through sound technical choices and future-proof design.
- Strong instinct for connecting low-level system architecture choices directly with company value.
What you can expect
- Frontier Product: Building state-of-the-art systems and state-machine architectures that redefine how modern developers interact with AI workflows.
- Elite Environment: Working alongside C-level executives, industry visionaries, and core platform architects with no corporate theater or bureaucratic overhead.
Responsibilities:
- Platform APIs & Orchestration: Build, optimize, and deploy orchestrator-style APIs on Kubernetes (managing operations like agent initialization, suspension, state synchronization, and secure reads).
- Asynchronous Distributed Jobs: Implement and scale distributed job queues and background workers for long-running indexing, code building, and release management tasks.
- Data Layer Architecture: Design, scale, and evolve the platform’s data layer—including database boundaries, optimized access patterns, and strong consistency models at scale.
- System Integrations: Seamlessly connect internal microservices and external webhooks with reliable event handling, transactional callbacks, and distributed handoffs.
- Production Operations: Own and advance logging, distributed tracing, alerting frameworks, and modern incident response workflows across production environments.
- Developer Experience (DX): Take ownership of local development environments, monorepo tooling, and internal productivity scripts.
- Monorepo Structural Evolving: Plan and execute large-scale codebase structural migrations without freezing product delivery timelines.
- CI/CD Pipelines: Own the architecture and continuous execution of deployment and integration pipelines end to end.
Recruitment process:
- 1.5-hour pair programming session with our client’s core engineering team.
- 1-hour technical interview with the Principal Engineer.
- Optional additional 1-hour conversation to explore deeper fit or alternative skillsets.
- Final decision and offer.
Perks in the office:
- Premium coffee selection
- Secure bike parking
- On-site shower facilities
- Free selection of beverages
- Complimentary snacks
- Modern, high-end office space
- No dress code policy
- Dedicated playroom and relaxation area
Benefits:
- Dedicated conference and professional development budget
- Flexible working hours
