Who are we searching for?

We're looking for a Head of Engineering who's already been the senior technical person at a small startup — writing code, making architecture calls, and keeping founders in the loop without being asked. 

You'll own engineering fully — the team, the delivery, the architecture, the quality bar, and the overall engineering state of the company. This is not a coordination role. You'll write production code daily on the hardest problems: AI agents, MCP infrastructure, forecasting systems, and financial analytics. You'll be the person who says what's doable, shapes scope, and decides how the team works.

The team is 4 engineers, 1 QA, and 1 Product Owner. The direction is set — we're looking for someone to run the room.

If that matches your experience, let's talk.

What are your responsibilities?

• Build and maintain the forecasting agent and financial analytics platform
• Develop MCPs and the agent orchestration layer
• Own dashboards, access controls, and reporting infrastructure
• Build the AI coding culture across the team — by example, not by policy
• Drive end-to-end engineering delivery: planning, estimation, and accountability
• Own technical architecture across the full stack and AI layer
• Negotiate and control scope — before it reaches the team
• Maintain code quality, CI/CD, automated testing, and deployments
• Run 1:1s, give feedback, and support engineer growth
• Lead hiring as the team scales
• Send engineering reports proactively — blockers, throughput, what changed, and why
• Translate technical constraints into business language for founders and non-technical stakeholders

What are the preferred requirements for the role?

• 5+ years of engineering experience, 2+ years as Tech Lead or Head of Engineering at a startup under 50 people — still writing code daily
• TypeScript / Node.js · React, ideally NestJS knowledge
• Shipped AI in production: LLM integration / RAG, agents, MCP — real users, not demos
• Daily AI tooling: Claude Code, Cursor, Augment, or equivalent 
• People leadership experience: 1:1s, feedback, hiring
• B2B SaaS experience, preferably in fintech or a data-heavy domain
• Clear and proactive communication with C-level executives
• C1 English

Good to have:

• Financial API integrations: QuickBooks, Xero, Stripe, or similar
• FP&A domain: P&L, forecasting, budget vs. actuals
• Side projects or open source built with AI tooling
• Experience with MCPs and agent orchestration

Reporting Structure: reporting to the CEO

Recruitment Process:

1. Recruiter interview 
2. Tech fit & live coding session with Fuel engineers 
3. System Design and Behavioural interview with Fractional CTO 
4. Culture fit interview with the CEO

Why work with us?

• You'll own engineering fully — not inherit someone else's decisions
• Work on real AI: production agents, MCP infrastructure, financial intelligence that SMBs actually depend on
• Small team, high trust — no politics, no layers, no meaningless meetings
• Competitive salary + equity 
• Freedom to define how engineering works — tooling, process, standards are yours to set
• Flexible schedule and async-friendly culture
• 18 days paid vacation per year + paid sick leave
• You'll see the impact of your work directly — in the product, in the team, and in the businesses we serve

About the role

At RubyLabs, we’re seeking a senior AI Engineer (Node.js / Next.js / TypeScript) to shape our AI infrastructure and drive production-ready LLM experiences. You’ll work in a modern stack, making data-driven decisions around model performance, reliability, and cost.

You’ll own advanced prompt systems, structured outputs, and complex LLM workflows using LangChain or LlamaIndex. Observability, debugging, and evaluation are core to the role, leveraging Langfuse and AI gateways like OpenRouter to continuously improve model quality and operational efficiency. You’ll take full ownership of key AI features from experimentation to live production.

Key Responsibilities

• Advanced Prompt Engineering: Designing complex, dynamic prompt templates with conditional logic and efficiently reusing information and context within prompts to maximize generation quality and reasoning.
• Structured Outputs & Schemas: Implementing various response schemes (JSON mode, function calling, Zod/JSON schemas) to ensure AI outputs are predictable and ready for seamless integration into application logic.
• Prompt Engineering & Evaluations: Building robust evaluation pipelines and using Langfuse to collect feedback and score the quality of responses in real time.
• Tracing & Debugging: Performing deep debugging of complex LLM chains using Langfuse traces to identify bottlenecks and optimize for cost, latency, and context window usage.
• AI A/B Testing: Running systematic experiments across different models via OpenRouter (e.g., comparing Claude 3.5 Sonnet vs. GPT-4o) and analyzing results based on quantitative metrics.
• Data-Driven Decisions: Making deployment decisions for new prompts or models strictly based on quantitative benchmarks and trace data, rather than intuition.
• Output Scoring & Analysis: Developing scoring systems to analyze the “Problem → Solution” chain and identify root causes of hallucinations or logic errors using Langfuse analytics.
• Model Performance & Fine-Tuning: Regularly re-evaluating model performance as new architectures emerge and performing fine-tuning when necessary to meet specific domain requirements.

Qualifications

• Node.js & Next.js: Deep knowledge of the stack to build reliable services and handle complex LLM-generated data.
• Dynamic Prompting Skills: Proven experience in building prompts where content is highly dependent on input variables and context injection.
• OpenRouter Experience: Experience working with unified APIs, managing rate limits, and selecting the most cost-effective models for specific tasks.
• Langfuse (or similar): Understanding of LLM observability principles — setting up tracing, creating test datasets, and integrating scoring systems.
• Evaluation Methodology: Experience with frameworks like RAGAS or building custom “LLM-as-a-judge” systems.
• Analytical Mindset: Ability to transform raw generation logs into actionable business metrics and technical insights.
• Iterative Mindset: Focus on continuous product improvement through constant feedback loops.

Nice to have

• Fine-Tuning: Practical experience in fine-tuning models for specific domain tasks or JSON compliance.
• RAG Architecture: Understanding how to build and optimize Retrieval-Augmented Generation systems, including indexing, retrieval, and re-ranking.
• Python: Basic knowledge for working with data science scripts or AI evaluation libraries.

Location

Be part of our fast-growing team and seize this excellent opportunity for personal and professional growth!

Interview Process

After submitting your application, we conduct a thorough review which typically takes 3 to 5 days, but may occasionally take longer due to the volume of applications received. If we see a potential fit, we proceed with the following steps:

• Recruiter Screening (40 minutes)
• Technical Interview (60 minutes)
• Final Interview (30 minutes)

What you will actually do

• Design and build complex API integrations connecting internal and client systems — Wrike, Azure DevOps, Claude, and others
• Take full ownership of development tasks — from requirements and architecture through to testing and release
• Build new products, features, and internal tools from scratch — not just scripts, but shippable code
• Automate repetitive workflows — status and data syncs, report generation, and recurring manual processes
• Work with Claude as your primary coding partner — prompt, iterate, and ship production-ready code
• Create weekly POC demos — prove the concept fast, refine later
• Continuously improve existing systems, reduce technical debt, and contribute to overall product direction
• Share findings with the team — short demos, Slack notes, or writeups when something works well

What we look for

Must have:

• You treat AI as a primary development tool — not a novelty, not a limitation
• When AI gives a weak result, you improve the prompt, guide the iteration, and validate the output instead of defaulting to manual work
• Solid coding ability in any language — Python, JS, C#, or similar
• Good English, B2 or above — all AI tools, docs, and team communication are in English
• A side project, automation, or experiment you built with AI — even unfinished
• Strong initiative and fast learning, not polished seniority

Nice to have:

• Hands-on experience with Claude, Cursor, Copilot, or similar AI coding tools
• Familiarity with Azure DevOps or GitHub CI/CD
• Latvia and Eastern Europe preferred - must be able to overlap with Riga working hours

This role is not for you if…

• You think AI is useful for autocomplete but not for real development work
• Your reaction to an AI mistake is “see, it doesn’t work” rather than “let me fix the prompt”
• You need complete specifications before you can start building
• You prefer proven, established tools over experimenting with new approaches
• You see AI as a shortcut — not as a core part of how you work
• You immediately assume it is complicated and time-consuming

We are not filtering by years of experience. We are filtering by mindset and drive.
This role is best suited to someone genuinely passionate about coding and AI.

What we offer

• Unlimited paid access to Claude, Cursor, and other AI tools from day one to get the job done
• Mostly remote — come into the Riga office when it makes sense
• Health insurance after probation period
• A team that actively uses AI daily — you will not be the only one experimenting
• Real projects with real problems — no invented tasks, no busywork
• A fast-growing company building its AI capabilities now — room to grow with it

How to apply

No cover letter. No template. Just send your CV to info@aaprojekts.lv and include:

• education background — started or completed IT-related education is required
• language skills
• show us something you built, automated, or improved using AI in the last 3 months
• brief IT experience mention, if applicable

We care most about your way of thinking, your ability to learn, and your interest in building useful things with AI.

* All candidates will be required to complete a time-limited task using AI
