The Role

We're hiring a Senior Director, Software Development, Test Automation Systems to architect and build Lila's test automation platform and quality engineering practice for our AI-powered scientific and lab automation products. Reporting to the VP of Engineering, you'll own the test automation system, CI/CD test infrastructure, AI-driven test tooling, and the eval discipline that hold the bar across our SDLC.

This is a builder-leader role. You will drive the quality vision, write requirements, make sharp build-vs-buy calls, drive execution, and build and lead a small (3-5 person) team that delivers leverage. The operating model is federated: you own the platform, standards, and metrics; engineering teams own test execution. You scale through tooling and influence.

As you scale into this role, you'll also stand up the QC framework for our lab automation system - the validation patterns, harnesses, and contracts that science operations teams will operate day-to-day. Data integrity and ALCOA+ compliance are foundational to everything you build.

What You'll Be Building

What You'll Do

Architect and ship the test automation platform

• Design and build the test automation platform - frameworks, fixtures, golden datasets, test orchestration, and reporting - that the engineering org adopts by default
• Set standards across unit, integration, contract, end-to-end, regression, performance, and chaos testing for backend services, the frontend monorepo, and data pipelines
• Treat platform adoption, flake rate, and time-to-signal as first-class engineering metrics

Make build-vs-buy decisions with conviction

• Own the buy/build/borrow strategy across test infrastructure, eval platforms, browser/device clouds, observability, and lab QC tooling
• Justify every choice with TCO, signal quality, integration cost, and time-to-leverage - and revisit decisions as the org and tech landscape evolve
• Bias toward leverage: buy commodity capabilities, build the differentiators (Lila-specific AI evals, lab QC, scientific data integrity)

Modernize CI/CD for fast, reliable signal

• Own the test execution layer of CI/CD: parallelization, caching, hermetic environments, ephemeral preview envs, and affected-only test selection across our Nx monorepo/microservices.
• Build retry, quarantine, and impact-analysis systems so signal stays sharp as the org scales
• Drive change-failure rate, MTTR, Test effectiveness, pipeline efficiency, coverage, and PR-to-prod lead time as outcomes

Drive AI-driven test automation

• Apply LLMs across the full test lifecycle: test generation from specs and PRs, self-healing UI tests, synthesis, visual regression with vision models, and AI-assisted failure triage
• Validate every AI-generated test through evals - no LLM-authored test ships without proof it doesn't degrade signal
• Establish the eval discipline for Lila's AI/agent stack: golden datasets, rubrics, regression suites, offline + online evaluation pipelines

Define and operate the quality metrics system

• Define quality SLOs and adoption metrics by team and service: coverage, escape rate, MTTR, change-failure rate, eval pass rate, lab QC violation rate
• Build dashboards that make quality visible from PR to executive review
• Apply Google SRE practices to prioritize where investment goes

Mid-long term - Stand up the QC framework for lab automation

• Design the validation framework, harnesses, and contracts that lab and Science Ops teams will operate
• Embed ALCOA+ principles: data integrity, audit trails, lineage from sample  instrument  output
• Partner with Research Ops on pre-flight, in-flight, and post-flight validation patterns for autonomous lab execution

Lead and coach across the engineering org

• Build a 3-5 person team of test automation engineers focused on platform leverage, not on writing tests for other teams
• Coach engineering teams on test design, quality investments, and adoption - make it cheaper to test well than to ship blind
• Translate UX and customer issues into testable contracts and platform improvements

First 6-12 Month Outcomes

• First 90 days: Establish baselines - flake rate, time-to-signal, change-failure rate, coverage, and current build-vs-buy footprint - and publish a quality scorecard with the first set of SLOs. Hire or onboard the initial 1-2 platform engineers.
• By 6 months: Ship v1 of the test automation platform adopted by at least one flagship engineering team by default; land CI/CD test-execution improvements (parallelization, affected-only selection, flake quarantine) with measurable time-to-signal reduction. Stand up the eval discipline (golden datasets, rubrics, regression suites) for the AI/agent stack.
• By 12 months: Drive default platform adoption across the engineering org; demonstrate AI-driven test automation in production with eval-gated rollout. Deliver the first operating version of the lab automation QC framework with ALCOA+ audit trails, validated end-to-end with Science Ops. Quality is visible from PR to executive review via live dashboards.

What You'll Need to Succeed

Required Qualifications

• 10+ years in software engineering, with 5+ years leading test automation, quality engineering, or platform/SRE-adjacent functions
• 3+ years managing engineers, including building or scaling a team
• Strong software architect/engineer. You write designs your team wants to read and review. Python and/or Typescript hands on expertise is highly desirable.
• Deep CI/CD expertise. GitHub Actions or equivalent at scale, monorepo build/test orchestration (Nx, Turborepo, or Bazel), test parallelization and caching, hermetic environments, ephemeral preview envs, flake quarantine, and test impact analysis
• Demonstrated build-vs-buy judgment. You've made and defended decisions on test infra, eval platforms, browser/device clouds, and observability - and can articulate the TCO and signal trade-offs that drove them
• Hands-on AI-driven test automation experience. Using LLMs to generate, maintain, or triage tests in production, with rigorous eval validation. Fluency with eval frameworks
• Track record of standing up a test automation platform that engineering teams adopted - not one bolted on
• Working knowledge of Google's SRE practices and a point of view on when they apply to pre-production quality
• Metrics-driven leader who drives outcomes through platform leverage and influence, not gatekeeping
• Customer- and UX-first instincts: treats test automation as a vehicle for user experience, not a cost center

Bonus Points For

Nice to Have

• Experience in GxP-regulated environments or scientific data integrity programs
• Experience with lab automation, LIMS, or other instrument-driven systems
• Multi-tenant SaaS quality at scale
• Exposure to event-driven systems, agent orchestration frameworks, or MCP
• Performance/load testing or chaos engineering background
