"The AI company that's revolutionizing Hollywood"

Flawless is transforming Hollywood with assistive AI. Our tools empower filmmakers to edit, localize, and refine performances while preserving artistic intent.

Designed to support, not replace, artists, our technology expands what is possible on screen and gives creators freedom to tell stories with greater impact and reach audiences in new ways. From enabling seamless multilingual releases to eliminating the need for costly reshoots, Flawless solves critical challenges that slow down productions and limit distribution.

We are also setting the standard for ethical AI in entertainment. Our Artistic Rights Treasury (A.R.T.) is a rights management solution that protects artists and rights holders, ensuring that innovation moves forward with transparency and respect for creative ownership.

What we are looking for:

We're looking for a senior backend leaning engineer who thrives at the intersection of product and technology. You'll work cross-functionally with design, product, and backend teams to build polished, performant products and scalable systems. The ideal candidate is highly autonomous, product‑minded, and excited by the challenge of shipping impactful features in a fast‑moving environment.

What Success Looks Like in 6 Months

You have shipped multiple high‑impact features, contributed to architectural decisions, and become a go‑to engineer for solving complex product challenges.

Responsibilities:

• Design, build, and maintain core systems and APIs using Python, ensuring code quality, scalability, and performance.
• Own end‑to‑end development across the stack – from architecture and data modeling to deployment and monitoring – with some willingness/ability to collaborate on the frontend when needed.
• Review and mentor code contributions from peers, driving engineering best practices and raising technical standards across the team.
• Collaborate with product managers, other engineers, and designers to translate requirements into robust features that delight our users.
• Work closely with other engineers to define and evolve API contracts, ensuring seamless integration and performance across systems.
• Contribute to architectural discussions, technical planning, and roadmap prioritisation.
• Troubleshoot, debug, and optimise services across multiple environments and distributed systems.
• Enhance developer tooling, CI/CD pipelines, and observability to improve engineering velocity and reliability.
• Champion resilient, maintainable code and a culture of continuous improvement.

Qualifications

Must-haves

• Strong expertise in Python OR any other high level object orientated language and experience with at least one modern web framework (e.g., FastAPI, Django, or Flask).
• Proven experience designing and shipping production‑grade backend systems and APIs.
• Solid understanding of databases, data modeling, and query optimisation (SQL and/or NoSQL).
• Experience with containerisation and cloud environments (e.g., Docker, AWS, GCP, Azure).
• Ability to navigate ambiguity and make pragmatic technical trade‑offs in fast‑changing environments.
• Strong problem‑solving skills and a product‑focused mindset.
• Experience with code reviews, mentoring, and enforcing engineering standards.

Bonus

• Familiarity with Python.
• Experience with GraphQL, Auth0, or authentication/authorization systems.
• Exposure to ML or Data intensive products.
• Prior work in smaller, fast‑moving environments where autonomy and adaptability are key.

Interview Process

At Flawless, our team and interview process want to help you show your best self. We'll dive into past projects and simulate working together.

Our interview process is three interview rounds with some casual Zoom (or in‑person) coffee in between to get to know each other:

• Recruiting Screen: 30‑45 minute call with our recruiting team (We want to discuss your interests and motivations as well as the practical details and make sure that Flawless would be a good fit for you).
• Coding Interview: 60 minute Zoom. This will be a technical paired‑programming task with one of our engineering team.
• Team Interview: ~2 hours onsite interview where you will meet a variety of your potential future colleagues (We will have specific sessions that focus on how you collaborate with others and your technical experience).

Your Recruiter and hiring manager will be your main point of contact and prepare you for interviews. You'll meet 4 to 6 people from across the business. (We make sure that you have time in each interview to ask them questions). If we don't give an offer, we'll provide feedback!

Why work at Flawless?

You will be working in an environment based on trust, autonomy and collaboration, and this is a great opportunity for someone who wants to be part of a growing company in its most exciting stage of development. You can play a part in shaping the future of a company that's caring, creative and collaborative.

In addition to this, you'll also receive:

• Autonomy
• A hybrid working environment
• Competitive Salary
• All permanent employees receive generous stock options

I don't meet all the listed requirements‑should I still apply?

Absolutely! Research shows that women and under‑represented groups often hesitate to apply unless they meet every qualification, but at Flawless, we actively work to break down those barriers. We believe diverse perspectives, experiences, and backgrounds make us stronger, and we are committed to supporting and elevating under‑represented talent. If you're excited about the role, share our values, and believe you can contribute meaningfully, we encourage you to apply—even if you don't meet every single requirement. Your unique skills and perspective matter, and we'd love to hear from you.
