The intersection of financial technology and artificial intelligence continues to create high-impact opportunities for experienced engineers. One such role is the Tech Lead Full-Stack Rails Engineer position at Mitre Media, a company focused on building AI-powered tools that help investors make smarter decisions.
This role is designed for senior engineers who not only write high-quality code but also shape system architecture, guide teams, and integrate advanced AI capabilities into real-world applications. With a strong emphasis on both Ruby on Rails expertise and large language model (LLM) integration, it represents a modern evolution of full-stack engineering leadership.
Company Overview
Mitre Media operates in the FinTech space, delivering data-driven platforms that support millions of investors. Its portfolio includes well-known financial platforms such as Dividend.com and MutualFunds.com, which provide research tools, analytics, and insights for both individual investors and institutional clients.
Over the years, the company has built partnerships with major asset managers like BlackRock and Vanguard, highlighting its credibility within the financial services ecosystem.
A key differentiator for Mitre Media is its integration of AI—particularly LLMs—into its platform, enabling richer data insights and more personalized user experiences.
Role Overview
As a Tech Lead Full-Stack Rails Engineer, you will take ownership of designing and delivering scalable web applications powered by AI. The role combines deep backend expertise with frontend development and AI integration, all within a microservices-based architecture.
Reporting directly to the CTO, you will collaborate with a small, highly focused team to build and enhance products across the company’s portfolio. This is not a purely managerial position—you will remain hands-on, contributing to both architecture and implementation.
The work environment is remote-first, with optional in-person collaboration in cities like Toronto or New York. The company operates within a time zone range of ±3 hours from Eastern Time to ensure smooth collaboration.
Key Responsibilities
This role spans multiple areas of technical leadership and execution. Core responsibilities include:
- Designing and maintaining applications built with modern Ruby on Rails (including Rails 8)
- Integrating large language models into microservices for real-time and stateful user interactions
- Enhancing frontend experiences using tools like Hotwire, StimulusJS, or React
- Optimizing AI model performance, focusing on latency, cost, and scalability
- Collaborating with leadership and cross-functional teams to deliver high-impact features
- Making architectural decisions that influence long-term platform evolution
You will also play a mentorship role, guiding other engineers and promoting best practices in code quality and system design.
Technical Requirements
Backend Expertise
Candidates are expected to have strong experience in:
- Ruby (5+ years at an advanced level)
- Ruby on Rails (preferably versions 6 through 8)
- Relational databases such as PostgreSQL or MySQL
- Search and caching technologies like Elasticsearch and Redis
- Containerization tools such as Docker
Frontend Development
While backend skills are critical, the role also requires frontend capabilities, including:
- JavaScript (ES6+) or StimulusJS
- Tailwind CSS for styling
- Solid understanding of HTML and HTTP protocols
AI Integration Skills
A distinguishing feature of this role is its focus on AI. Candidates should have experience:
- Integrating AI or machine learning models into web applications
- Working with LLM frameworks such as LangChain or Hugging Face
- Using APIs from providers like xAI or Anthropic
This combination of web development and AI integration is central to the role’s impact.
Preferred Skills
While not mandatory, the following experience can strengthen your candidacy:
- Kubernetes for managing microservices at scale
- React for advanced UI components
- Graph databases for handling complex financial datasets
- Contributions to open-source projects in Ruby on Rails or AI
Soft Skills and Leadership Qualities
Beyond technical expertise, Mitre Media values professionals who demonstrate:
- An entrepreneurial mindset and genuine interest in AI and financial technology
- Leadership abilities, including mentoring and team motivation
- Strong problem-solving skills with a focus on execution
- Clear communication in remote and collaborative environments
- Attention to detail and commitment to maintainable, high-quality code
The ideal candidate is comfortable balancing leadership responsibilities with hands-on development work.
Work Environment and Methodology
The company uses a remote-first hybrid model, encouraging occasional in-person collaboration while supporting distributed teams. Project management follows the ShapeUp methodology, which emphasizes delivering meaningful outcomes rather than strictly adhering to rigid timelines.
This approach allows teams to prioritize quality and impact, adjusting scope when necessary to meet deadlines without compromising core functionality.
Compensation and Benefits
The role offers competitive compensation ranging from $160,000 to $200,000 (CAD or USD), depending on experience. Additional benefits include:
- Budget for attending industry conferences such as NeurIPS and RailsConf
- Access to modern AI tools and platforms for experimentation
- Opportunities for continuous learning and professional growth
- Flexible remote work arrangements
Why This Role Stands Out
Several aspects make this opportunity particularly attractive for senior engineers:
1. Real-World Impact
You will contribute to tools used by millions of investors, influencing how financial decisions are made.
2. Advanced Technology Stack
The combination of Rails 8, microservices, and LLM integration places this role at the forefront of modern web development.
3. Direct Influence
Working closely with executive leadership provides a rare opportunity to shape product direction and technical strategy.
4. Balanced Autonomy
Engineers are trusted to take ownership while collaborating within a supportive, experienced team.
Final Thoughts
The Tech Lead Full-Stack Rails Engineer role at Mitre Media is well-suited for experienced developers who want to operate at the intersection of AI and financial technology. It requires a rare blend of backend mastery, frontend capability, and AI integration expertise, along with the leadership skills to guide a team and influence product outcomes.
For professionals who enjoy building scalable systems, working with cutting-edge tools, and contributing to meaningful financial applications, this role offers both challenge and opportunity in equal measure.
