QA / Software Engineer in Test (SDET)

Cascade is an AI-native, end-to-end filmmaking platform, built by filmmakers, for filmmakers. In one seamless, web-based environment, creators can go from first idea through script, storyboard, character generation, scene assembly and final edit – without leaving the platform.

Our Open Beta is live, and we've moved from launch mode into growth – building a roster of creative partners and an audience of independent filmmakers and directors who are making the case for our platform.

The creator economy is $250 billion and growing at 22% a year. Over 50 million filmmakers and creators are drowning in fragmented tools and broken workflows. Cascade replaces the stack.

THE ROLE

Build the automated quality system that allows Cascade to release quickly without repeatedly breaking critical customer workflows. This is not a manual-only QA role. It owns automated end-to-end, API, contract, and visual-regression testing, along with release gates and failure investigation.

WHAT YOU'LL OWN

• Automated coverage of the most important customer journeys.
• End-to-end testing of project setup, AI generation, editing, collaboration, and output workflows.
• Visual-regression coverage for complex editor surfaces.
• API and contract tests for critical backend boundaries.
• Tests for failed, cancelled, retried, and long-running operations.
• Release gates, parallel execution, stable fixtures, and actionable failure reporting.
• Flaky-test identification and quarantine.
• Regression tests for production incidents.
• Quality metrics and release-readiness reporting.

YOU'LL NEED

• 5+ years QA/software engineering
• Strong automated-testing experience for modern web applications.
• Ability to design stable tests for asynchronous workflows without brittle fixed delays.
• Good judgement about release-blocking versus non-blocking failures.
• Ability to work closely with developers without becoming a manual testing bottleneck.

NICE TO HAVE

• Testing creative, media, canvas, or graphics-heavy software.
• Visual-regression systems.
• Performance, load, and cross-device testing.
• Testing AI-generated or non-deterministic outputs.

WHAT WE OFFER

• Competitive salary benchmarked against early-stage London tech.
• A genuinely exciting product to direct for – built by filmmakers, for filmmakers, at the frontier of AI.
• A team culture built on craft, speed and ambition. We take the work seriously, not ourselves.
• The chance to define Cascade's creative voice and build the function as we grow.

OUR PRINCIPLES

We hire people who share these values:

• We build from scratch, we do not maintain the status quo: Builder mindset
• Everything we do is in service of the storytellers using our platform: Creator-first
• Speed matters, and so does quality - we do not sacrifice one for the other: Move fast, ship well
• We say what we think, give feedback clearly, and expect the same in return: Honest and direct
• We use AI at every level,including in how we work and expect our team to do the same: AI-native

OUR BRAND VALUES

• Story first. Always. Every decision exists in service of the story. The technology is the means. The story is the thing. Every product decision, every design choice, every line of copy exists to serve one purpose — getting great stories made.
• Democratise great filmmaking. Talent is everywhere. Opportunity isn't. Cascade exists to level the playing field — so the best ideas get made regardless of budget, backing or postcode.
• Supercharge the human. Don't replace them. Storytelling is an art. AI is a tool, not a creative director. The best work comes from people with vision, instinct and an understanding of performance, pacing and story. Cascade is designed to supercharge that talent — not replace it.
• Slick by design. Relentless by nature. Cascade is built to be powerful, intuitive and genuinely easy to use. And we believe things can always be better, so we'll never stop listening, improving and working to support the people using Cascade.
