Senior Data Infrastructure Engineer

We’re looking for a Senior Data Infrastructure Engineer to architect and operate high-performance systems at scale using AI as a force multiplier.

This role has fundamentally shifted. You’re no longer constrained by typing speed or the breadth of APIs you’ve memorized. With agentic coding tools, you can scaffold infrastructure, automation, and tooling at a pace that was impossible a year ago. The bottleneck has moved: it’s no longer implementation, it’s orchestration, decomposition, and direction.

You’ll design infrastructure in collaboration with AI, review and iterate on generated code, manage multiple complex workstreams simultaneously, and ship infrastructure improvements at a velocity that would have required a team of three six months ago.

This requires a specific skill set: the ability to think in systems, decompose infrastructure problems cleanly, direct AI-generated solutions, and review code critically. You need to be comfortable with “the AI and I built this together”.

We primarily build in Rust and expect you to be comfortable with it or excited to become highly proficient.

We also use Bash, SQL, and Python extensively, often orchestrating all of them through AI-driven workflows. If you’ve successfully used agentic coding tools (Claude Code, Cursor, GitHub Copilot X-level capabilities), that’s a strong signal. If you’re skeptical of AI-driven development, this role probably isn’t for you.

What Actually Changed

• Before (Pre-Agentic): You spent 60% of your time writing code, database migrations, Bash scripts, and monitoring configurations. The remaining 40% was architecture, decomposition, and problem-solving.
• Now (Agentic Era): You spend 20% of your time writing that same code-except you’re orchestrating AI to generate it, then reviewing and iterating. You spend the other 80% on what AI can’t do: deciding what to build, why certain tradeoffs matter, and managing multiple infrastructure improvements in parallel.

What this means for this role:

• Handling Debian server management, disaster recovery, and capacity planning-but with AI generating the majority of your automation scripts
• Designing PostgreSQL schemas and ClickHouse migrations-with AI scaffolding the implementation and you validating the design
• Building monitoring and observability systems-10x faster than before
• Managing 8+ bare-metal servers and 1.2 PiB of data
• Working across multiple infrastructure subsystems simultaneously

What You’ll Work On

Infrastructure Architecture & Orchestration

• Design high-performance data processing systems, primarily in Rust
• Architect reliable systems for PostgreSQL, ClickHouse, Elasticsearch, and time-series databases at scale
• Decompose complex infrastructure problems into tasks that AI can execute effectively
• Direct, review, and iterate on AI-generated infrastructure code
• Manage multiple infrastructure workstreams in parallel-something now feasible with agentic tools

Systems Administration & Operations

• Manage and operate 8+ bare-metal Debian servers with sophisticated automation
• Orchestrate infrastructure automation (Bash, configuration management, deployment tooling)
• Coordinate with remote hands for hardware installation, manage capacity, plan upgrades
• Build and maintain monitoring, observability, and alerting systems
• Troubleshoot the full stack: hardware, networking, OS, services, data

Performance Engineering Through Agentic Optimization

• Profile and benchmark systems; identify bottlenecks
• Iterate on optimization code-CPU, memory, query performance
• Reduce footprint while handling massive datasets by parallelizing optimization work
• Design systems optimized for bare-metal hardware without cloud provider constraints

Database Administration & Query Optimization

• Design PostgreSQL schemas and write optimized queries
• Maintain Elasticsearch indices; configure and optimize specialized databases
• Generate schema migrations, test them, iterate on tradeoffs
• Understand consistency, availability, and scalability tradeoffs deeply

Infrastructure Automation & Tooling

• Design AI-driven expert-level Bash orchestration
• Build automation that would previously have been too time-consuming to maintain
• Create monitoring, alerting, and observability infrastructure at scale
• Develop internal tools for the engineering team-deployment, debugging, performance analysis, Database & Data Architecture
• You understand databases as architectures, not just as APIs.
• OLTP vs OLAP fluency - you can articulate why PostgreSQL falls over on workloads ClickHouse eats for breakfast, and vice versa. You don’t reach for a columnar store because it’s trendy; you understand row vs columnar storage, vectorized execution, and what query shapes each is optimized for.
• Storage hierarchy thinking - hot path in Postgres, warm analytics in ClickHouse, cold/archival in object storage (S3-compatible) mounted into a data lake. You’ve made these tradeoffs in production.
• Data lake patterns - Parquet/columnar formats, object storage as a query target (DuckDB, ClickHouse over S3), and the operational realities of cheap storage + on-demand compute.
• Schema & query design under constraints - partitioning, sharding, materialized views, denormalization for analytics. Decisions based on access patterns, not dogma.
• Operational depth in Postgres - replication, vacuum behavior, index bloat, query planner quirks, lock contention. Schema design is table stakes; operating Postgres at scale is the differentiator.

Performance Engineering

• Track record optimizing systems for speed, memory efficiency, throughput
• Ability to profile, benchmark, and identify bottlenecks
• Designing systems where performance is a first-class concern

Infrastructure Automation

• Expert Bash scripting; command-line proficiency
• Ability to write automation that’s maintainable and reliable
• Configuration management or deployment tooling experience

Valuable Adjacent Backgrounds

• Infrastructure/SRE: You’ve built and operated production systems at scale
• Database specialization: Deep PostgreSQL, ClickHouse, or data warehouse expertise
• Performance engineering: You’ve profiled and optimized complex systems
• DevOps/platform engineering: You’ve built tools for other engineers
• Data lake / lakehouse experience: built or operated systems where object storage (S3, MinIO, Ceph) is a first-class query target, not just a backup destination.

Qualities We Value

• Systems thinking - You understand interdependencies and tradeoffs
• Decomposition skills - You break problems into tasks AI can execute
• Code review discipline - You validate AI-generated code carefully
• Ownership - You take responsibility for systems you build and maintain
• Communication - You explain technical concepts clearly
• Pragmatism - You make decisions based on constraints and tradeoffs, not dogma
• Curiosity - You dig deep and understand what you’re building

US$100K - 120K, Our infrastructure is physical. Real machines, real drives, real PCIe cards, real cabling. You won’t touch them (remote hands will) but you’ll direct that work. Concretely:

• Speccing a server upgrade (drives, NICs, RAM, expansion cards) and writing the work order for someone else to execute
• Diagnosing a failing drive or flaky NIC from SMART data, kernel logs, and ipmitool output
• Choosing a RAID layout, ZFS pool topology, or NVMe-over-fabric configuration based on workload, then living with that decision for years
• Coordinating maintenance windows and tolerating “ticket filed * tech arrives Wednesday”
