WHY THIS ROLE EXISTS
 

Most job ads describe a seat to fill. This one describes a problem worth solving. We are building a product that an IT services company in the United States depends on to run its entire operation: billing, ticketing, project management, and service delivery, all in one place. The company chose to build it themselves rather than accept a generic off-the-shelf tool, because they believe their operations deserve better. We agree. Now they need a developer who takes the same view of their own craft.
 

We are in the pre-sale stage of what we expect to become a 12-plus month engagement. The pilot is active. We are not posting this role to fill a pipeline spreadsheet. We are building a shortlist of people we would genuinely want on this team, so we are ready to move the moment the engagement confirms.
 

WHAT YOU WILL OWN
 

• Delivering complete product features end-to-end, from data model to interface, without waiting for handoffs
• Building and iterating on core modules: automated billing, ticket management, time tracking, and project coordination
• Writing code that your teammates can read, extend, and trust
• Contributing to the shared codebase alongside an existing in-house developer and a Tech Lead who sets technical direction
• Surfacing problems early and proposing solutions rather than waiting to be told what to do
• Participating actively in planning and estimation so timelines reflect reality, not optimism
   

WHAT WE ARE LOOKING FOR
 

• 4+ years of experience shipping production applications with React and Node.js
• Real ownership of features across the full stack, not just comfort on one side
• Experience with PostgreSQL or a comparable relational database in production
• The discipline to write maintainable code even when the deadline feels close
• Clear, direct communication in a distributed team context
• Availability to overlap with US CT for team calls (approximately 12:00 to 14:00 СТ time)
   

TECH STACK

• Frontend: React 18, TypeScript, Vite, Shadcn/ui, TanStack Query, Zustand
• Backend: Node.js deployed on Cloudflare Workers (serverless architecture)
• Database: PostgreSQL
• Auth and backend services: Supabase
   

No Supabase or Cloudflare Workers experience required. If you have worked with Firebase, AWS Lambda, or any serverless Node.js environment, you will find your footing quickly. 
 

HOW WE WORK
 

The team is distributed. The client is based in Dallas, Texas. 

Expect one or two overlap calls per week in the 12:00 to 14:00 CT time window. The rest of your day is yours to structure. We trust people to manage their own time, because we hire people who have earned that trust.

The Tech Lead owns architecture direction and stakeholder communication. Your focus is delivery. The two roles are designed to complement each other without competing.
 

WHAT WE OFFER
 

• A real product with a real deadline and real stakes, not a maintenance backlog
• A Tech Lead who sets clear direction so you can focus on execution
• Full-time engagement for the right person once the pilot confirms
• Transparent communication throughout the process, including honest updates if circumstances change
• A team that treats engineering craft as a professional standard, not a talking point

ABOUT SPEED AND FUNCTION
 

Speed and Function is a software engineering firm that builds custom products for growth-oriented businesses. We work on engagements that require both technical depth and the ability to operate as a trusted partner to business leaders. We are selective about the work we take on, because we believe the quality of what we build reflects who we are.

This engagement came through the community of founders and operators who take organizational development seriously. The client is not talking to other agencies. We are their only option, and we intend to earn that position every week.

HOW TO APPLY
 

Send a short note explaining why this specific role interests you, alongside your CV or LinkedIn profile. We do not need a cover letter that restates your resume. Tell us something about how you think about your work.

We are looking for a Full Stack Tech Lead with a strong frontend orientation to become a senior technical force for our client. This is a hands-on leadership role - you will be writing code every day, but you will also be the person others look to for architectural direction, technical decisions, and cross-stack ownership.

You are comfortable owning both the frontend experience and the backend systems that power it. You have the depth to make architectural calls on the full stack, and the communication skills
to align the team and stakeholders around them. Frontend-first in mindset, but no stranger to backend work when needed.

Key Responsibilities

• Lead the architecture and delivery of complex, full stack features across the platform
• Own frontend systems end-to-end while extending into backend (Node.js / NestJS) as the work requires
• Drive architectural decisions across both frontend and backend —with a focus on scalability, observability, and long-term maintainability
• Set technical standards, conduct thorough code reviews, and raise the bar across the engineering team
• Collaborate directly with product and design - wear many hats, bridge technical decisions with business context, and move fast without losing quality
• Lead client-facing technical projects spanning diverse industries, making a real-world impact with each deployment
• Contribute to and shape Ballerine's broader technology strategy
• Mentor and support engineers on the team, helping them grow their skills and ownership

• Actively contribute to open-source development in line with Ballerine's open-source
principles
• Leverage AI and LLM tooling in your day-to-day engineering - from prototyping and code
generation to integrating AI-powered features directly into the product

Requirements

• 8+ years of commercial engineering experience, with clear evidence of technical leadership
• Expert-level knowledge of React and TypeScript
• Strong backend proficiency: Node.js, NestJS, PostgreSQL, REST APIs
• Experience with cloud infrastructure — AWS preferred — and container orchestration (Kubernetes)
• Familiarity with microservices architecture, distributed systems, and scalable backend design
• Strong understanding of state management patterns and architecture at scale
• Strong understanding of security practices, particularly in fintech or regulated environments
• Demonstrated ability to take full ownership of projects and drive them to completion independently
• Startup experience - comfortable with ambiguity, fast iteration, and wearing multiple hats
• AI-native engineering mindset: actively leverages LLMs and AI tooling as part of your everyday development workflow
• Excellent English communication — able to articulate technical decisions clearly to any audience
• Proven remote work track record with consistent, long-term impact in previous roles

Nice to Have

• Hands-on experience with xState or similar state machine libraries
• Experience building LLM-powered product features - prompt engineering, RAG pipelines, AI agents, or OpenAI / Bedrock integrations
• Experience with Temporal, Redis, or Prometheus / Grafana
• Open-source contribution history
• Prior experience in identity verification, KYC/KYB, or financial compliance products
• Comfort working in the open — contributing to documentation, RFCs, or internal technical writing

What We Offer

• A high-impact, technically challenging role with real architectural ownership
• Work directly alongside a skilled, principled engineering team committed to modern solutions
• Genuine influence over Ballerine's technology strategy and roadmap
• Fully remote with flexible, asynchronous-friendly working culture
• Competitive monthly compensation reflecting your seniority and contribution
• The opportunity to join a high-growth fintech startup just ahead of Series A
