Staff Engineer, AI & Engineering Velocity

The company that’s defining creator marketing

Creator video ads are eating traditional advertising alive. Brands will spend over $100 billion on social ads in 2026 and the ads that actually work are made by everyday creators, not agencies.

Billo connects 22,000+ brands, including Google, Udemy, Panasonic, Bic, Monday.com and Costco, with the creators who make those ads.

• Top 10 creative partner for Meta globally
• 200,000+ videos delivered
• $10M+ paid out to creators

We’re a category leader in the U.S. and we’re building the AI-driven tech that solves every part of creator marketing, from the first creative idea to performance at scale.

Why we’re hiring for this role

The speed at which we ship and test initiatives is crucial in our rapidly changing industry. A year from now, I want our R&D team shipping at 10x speed. Things that take 2 weeks today should take hours.

We’re hiring a Staff Engineer to own AI & Engineering Velocity. You figure out how we go from idea to production fast and you lead by doing it yourself. Your win is everyone else getting faster, not you being the hero who ships everything.

What success looks like in 12 months

• We’re 10x faster from idea to production. Shipping a testable version of a feature is a same-day thing, not a sprint.
• AI is just how we build now. Claude Code and the tools around it are part of everyone’s day. And you’ve made it safe, with the tests, reviews and guardrails that let us move fast without blowing things up.
• The path is clear for the team. Our main repos and services are set up so AI works well on them and everyone has a clear, low-friction way to build with it.
• We run way more experiments and iterations, kill the bad ones fast and double down on the winners, because trying something barely costs anything anymore.

What you’ll actually do

This is a hands-on builder role with no direct reports, your influence comes from the code you write and how you get the team working, not from managing people. You’ll:

• Write production code with AI agents as a normal part of how you work and keep pushing what that workflow can do.
• Build the setup that lets any engineer ship fast with AI: prompts, context, conventions, tools and evals.
• Use AI across the whole job, not just writing code. Debugging, reviews, incidents, finding your way around the codebase.
• Put the guardrails in place that keep speed safe: testing, code review, security, tuned for a heavy-AI workflow
• Sit with engineers, level up their AI skills and unblock them. You spread this by showing people, not by handing down rules.
• Decide how we measure AI-enabled engineering, adoption, quality and impact on speed and actually track it

What we expect

We live by 4 values: accountability, growth mindset, collaboration and startup ownership pace. We expect you to live them too and add to the culture.

You’re probably a fit if:

• You’ve personally shipped real software fast with agentic coding tools and you can show us the difference it made.
• You write code other engineers trust and you know when AI output is gold and when it’s a trap.
• You actually want to make other people better. You’d rather make 10 engineers twice as fast than ship it all yourself.

Technical requirements

Must have

• Backend depth in Node.js (our main backend) and able to move into Python for AI/ML work
• Shipped LLM features for real users – embeddings, vector search, RAG, prompt engineering and evals
• Agentic workflow orchestration – hands-on with LangGraph or similar
• Comfortable across our data stack – PostgreSQL / Aurora-MySQL, DynamoDB, Redis, S3, plus BigQuery for analytics
• Fast, safe shipping habits – GitHub Actions / Docker pipeline, Datadog for observability

Preferred

• Working knowledge of AWS (Lambda, ECS, S3)
• LLM observability – Langfuse or similar
• Vector search / similarity systems
• TypeScript / React / Node SSR
• Feature-flagged experimentation – LaunchDarkly

Why Billo?

• Gross 7,500–9,000 eur / month + Stock options
• Hybrid, at least 3 days a week at our Vilnius Tech Park office
• Private health insurance after 3 months
• A personal learning budget, AI tools and subscriptions included
• The freedom to test ideas and actually ship them, not sit through months of review

Who this isn’t for

This is high-urgency, high-ownership work at the edge of how software gets built, often with no playbook to copy. You’ll be changing how a whole team works. If you want well-defined scope, settled process and a clean split between the people who decide and the people who code, this won’t be a fit.

Want in?

If turning weeks of work into hours and pulling a whole team’s speed up with you, sounds like the best part of the job, let’s talk.
