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.

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)

We are looking for an Email Compliance Manager to own all communication, ticket management, and compliance coordination with ESPs across a large client portfolio.

You will be responsible for writing, submitting, and managing all interactions with ESP support, compliance, abuse, and deliverability teams. You will act as the strategic communication layer between internal teams and ESPs, ensuring every issue is resolved efficiently and professionally.

You must understand how ESP compliance teams think, how deliverability systems operate, and how to frame communication to achieve optimal outcomes while protecting client accounts.

WHAT WE ARE LOOKING FOR

Must-have

• 3+ years in ESP-side, compliance, deliverability, or direct ESP communications roles
• Strong understanding of ESP compliance systems, abuse handling, and deliverability mechanics
• Exceptional written English (near-native or native level) — writing is your core tool
• Proven ability to manage 30+ clients across different niches simultaneously
• Strong risk identification and problem anticipation skills
• High attention to detail (errors in ESP communication have real consequences)
• Comfortable working flexible hours and across US time zones when required
• Able to operate across all niches without personal or moral restrictions

Nice to have

• Direct experience working inside an ESP (support, compliance, deliverability)
• Familiarity with major ESP internal processes and decision-making systems
• Experience coordinating cross-functional technical or compliance resolutions
• Background in email marketing or marketing operations

WHAT YOU WILL OWN

ESP & Compliance Ticket Management

• Own all ESP ticket submissions and lifecycle management across 30+ clients
• Track, prioritize, and manage all active tickets from open to resolution
• Ensure nothing is lost, delayed, or left without follow-up
• Maintain structured logs of all communications, statuses, and outcomes
• Prioritize tickets based on urgency, compliance risk, and business impact

ESP Communications & Written Strategy

• Write and send all communications to ESP support, compliance, and deliverability teams
• Handle responses to abuse complaints, compliance flags, warnings, and suspensions
• Adapt tone, framing, and strategy based on ESP, issue type, and client context
• Know when to escalate, push back, or concede to protect client accounts
• Ensure all communication is precise, professional, and strategically optimized

Risk & Compliance Management

• Identify deliverability and compliance risks before they escalate
• Understand downstream consequences of every ESP interaction
• Propose mitigation strategies to the Head of Project for high-risk situations
• Stay updated on ESP policy changes, compliance rules, and deliverability trends
• Anticipate issues before they become account-threatening problems

Internal Coordination

• Work closely with email marketers, project managers, and production teams
• Translate ESP requirements into clear internal action items
• Ensure required changes are implemented before responding back to ESPs
• Maintain clear stakeholder communication on all ticket statuses and outcomes
• Follow through until every issue is fully resolved

WHO FITS THIS ROLE

The ideal candidate has worked on the ESP side and understands exactly how compliance and support teams evaluate risk, requests, and sender behavior.

They are a strategic writer who understands that every word sent to an ESP affects outcomes. They can manage a large portfolio of clients without losing track of detail, risk, or urgency.

They are fast, precise, and highly detail-oriented. They think several steps ahead, identifying risks before they become incidents.

They are comfortable working across all niches and understand that this is a behind-the-scenes operational role, not a client-facing or visibility-driven position.

WHO WE ARE

We are a fast-growing operation managing email marketing and deliverability across 30+ clients in multiple niches. We handle all ESP communications and compliance processes on behalf of our clients entirely behind the scenes. The role acts as the final point of contact with email service providers (ESPs), where precision, strategy, and speed directly impact client deliverability and account safety.

This is a high-volume, high-stakes environment. A missed ticket or poorly framed response can result in account restrictions or permanent suspension.

You will report directly to the Head of Project and work closely with internal teams to ensure all ESP issues are resolved end-to-end.

Flexible availability is required. ESP compliance issues do not follow business hours.
