Full Job Description

📋 Description

• Own the architecture and delivery of backend services that power Smartly.io’s AI-driven campaign optimization engine, directly influencing how millions of ad creatives are generated, tested, and deployed for global brands.
• Design and evolve resilient, high-throughput microservices in Python and TypeScript that sit at the heart of our ad-tech stack, handling petabyte-scale image, video, and text assets while guaranteeing sub-second latency for real-time bidding decisions.
• Partner with data scientists to productionize state-of-the-art computer-vision and NLP models, building scalable training pipelines, feature stores, and online inference endpoints that run on Kubernetes and leverage GPU autoscaling.
• Translate complex marketing objectives—such as ROAS targets, audience segmentation rules, and brand-safety constraints—into elegant technical solutions, collaborating daily with product managers, designers, and customer success teams.
• Champion clean-code practices, comprehensive unit/integration testing, and rigorous monitoring (Prometheus/Grafana) to ensure 99.9 % uptime for services that process billions of events per day across Facebook, TikTok, Snapchat, and Pinterest APIs.
• Lead technical planning and retrospectives, breaking epics into sprint-sized deliverables, estimating effort with story points, and continuously refining our agile ceremonies to keep the team laser-focused on customer impact.
• Mentor mid-level and junior engineers through pair programming, architecture reviews, and lightning talks, raising the bar for software craftsmanship and fostering a culture of psychological safety and continuous learning.
• Contribute to the open-source community by releasing internal tooling, writing technical blog posts, and speaking at meetups—amplifying Smartly.io’s reputation as a thought leader in AI-powered advertising.
• Experiment fearlessly: run A/B tests on new ranking algorithms, explore multi-modal generative models for ad creative, and iterate quickly with feature flags and canary deployments to de-risk bold ideas.
• Optimize cloud spend by profiling CPU, memory, and network usage, rightsizing Kubernetes pods, and negotiating reserved-instance pricing—turning infrastructure into a competitive advantage.
• Build self-service data pipelines that allow marketers to upload product feeds, apply dynamic creative templates, and receive near-real-time performance dashboards—empowering non-technical users to leverage AI without friction.
• Ensure compliance with GDPR, CCPA, and platform policies by embedding privacy-by-design principles into every service, from data encryption at rest to automated PII redaction in creatives.
• Collaborate with the Infrastructure team to roll out blue-green deployments, chaos engineering drills, and regional failover strategies—making our platform bulletproof during Black Friday traffic spikes.
• Drive cross-functional initiatives that reduce deployment lead time from hours to minutes, automate dependency updates with Renovate, and enforce security scanning in CI/CD to ship features faster and safer.
• Influence the product roadmap by synthesizing customer feedback, competitive analysis, and emerging AI research into actionable engineering proposals that deliver measurable ROI.

🎯 Requirements

• 5+ years building production-grade backend services in Python or TypeScript, with deep expertise in REST/gRPC APIs, PostgreSQL, and Kubernetes.
• Proven track record of deploying and scaling ML models in real-time inference environments (TensorFlow Serving, TorchServe, or custom microservices).
• Strong grasp of distributed systems concepts—event sourcing, CQRS, eventual consistency—and hands-on experience with message queues like Kafka or RabbitMQ.
• Nice-to-have: hands-on experience with computer-vision or NLP libraries (OpenCV, Hugging Face Transformers) and familiarity with ad-tech standards (OpenRTB, Meta Marketing API).

🏖️ Benefits

• Fully-remote culture with flexible hours and annual home-office stipend so you can work wherever you thrive.
• €3,000 annual personal learning budget plus five paid learning days for conferences, courses, or certifications.
• Company-wide quarterly bonus tied to transparent OKRs, ensuring everyone shares in Smartly.io’s growth and success.
