Senior Backend Engineer (Go) | Studio AI

Creative Fabrica; Lisboa; Presencial; EUR 70 000 - 100 000; Tempo integral

Resumo da oferta

Creative Fabrica in Portugal is seeking a Senior Backend Engineer (Go) to architect and scale our multimodal generation pipeline. You will design high-concurrency Go microservices that orchestrate heavy AI workloads across media domains and deliver reliable, fast generation for a global creator audience.

You will optimize ConnectRPC and async pipelines (Kafka, SQS), work with AWS (EKS, S3, Lambda), and collaborate with AI researchers to turn model outputs into a polished One Person Studio

Qualificações

• Advanced Go engineering with extensive experience in building and scaling Go services in high-traffic SaaS environments.
• Ability to design microservices that leverage asynchronous processing (Kafka & SQS) and low-latency communication (gRPC/ConnectRPC/GraphQL).

Responsabilidades

• Orchestrate multimodal workflows: design and scale Go-based microservices that manage AI generation lifecycles.
• Performance engineering: optimize ConnectRPC services and async pipelines (Kafka + SQS) for long-running inference tasks.
• Build the creative engine: develop backend logic for multimodal orchestration and advanced features.
• Data & infrastructure: collaborate with AWS, manage data throughput, and integrate with storage/compute clusters.
• Collaborate with AI researchers: bridge model outputs to a polished One Person Studio UX.

About Creative Fabrica

Creative Fabrica is a subscription platform serving millions of creators, designers, and crafters worldwide. We're built on the principle that everyone can be creative. We remove what stands in the way: expensive software, technical expertise, and time-consuming production.

Our Studio AI suite offers more than 26 specialized AI tools that automate technical work: generate custom images, remove backgrounds, create fonts, and produce publication-ready designs in minutes instead of hours.

Our content library contains 15+ million commercially-licensed fonts, graphics, SVGs, and templates, giving you professional-quality building blocks without the expense or time of creating assets from scratch.

About the team: Studio AI

Studio AI is Creative Fabrica's bet on what creative software looks like when AI is the default, not a feature.

We built a single platform where anyone can generate and edit images, video, audio, 3D models, and vector graphics using state-of-the‑art generative AI. Our tools serve hundreds of thousands of creators every day, from hobbyist crafters to professional designers and everything in between, all in one place.

We move fast, integrate frontier models into production‑ready workflows, and build the infrastructure that gives creators every tool they need to turn any idea into professional‑grade media, at scale.

About the role

As a Senior Backend Engineer (Go), you will be the architect of our multimodal generation pipeline. You won't just be building APIs; you’ll be designing the high-concurrency systems that orchestrate "heavy" AI workloads across any media domains. Your goal is to make complex, multi step AI generation feel instantaneous and reliable for a global audience of creators.

What you will do:

• Orchestrate Multimodal Workflows: Design and scale Go-based microservices that manage the lifecycle of AI generations.
• Performance Engineering: Optimize our ConnectRPC services and async processing pipelines (Kafka + SQS) to handle long-running, resource-intensive inference tasks without compromising platform stability.
• Build the Creative Engine: Develop the backend logic for advanced features like multimodal orchestration.
• Data & Infrastructure: Work with AWS to manage massive data throughput and integrate with high-performance storage and compute clusters.
• Collaborate with AI Researchers: Bridge the gap between raw model outputs and a polished "One Person Studio" user experience.

What you will need:

• Advanced Go Engineering: Extensive experience building and scaling Go services in high-traffic, high-volume SaaS environments.
• Distributed Systems Mastery: Proven ability to design microservices that utilize asynchronous processing (Kafka & SQS) and low-latency communication (gRPC/ConnectRPC/GraphQL).
• Cloud Architecture: Deep knowledge of AWS (EKS, S3, Lambda) and experience managing complex compute environments.
• Product Rigor: A background in building professional-grade creative tools or media-heavy applications.
• Software Best Practices: A quality-first mindset regarding code reviews, testing strategies, and observability.

Nice to have:

• Media Processing Experience: Familiarity with handling varied media types (video transcoding, audio synthesis, vector manipulation).
• AI Infrastructure: Experience with model serving at scale or managing GPU-accelerated workloads.
• Entrepreneurial Mindset: Experience in a fast-paced environment where you help define the product vision and iterate quickly.

Is this you?
