JOB DESCRIPTION: TECHNICAL LEAD (B2B SaaS / Fintech Infrastructure)

Product Domain: Large-scale B2B SaaS platform integrating connectivity APIs, marketplace ecosystems, and transaction processing networks.

About the Role

We are engineering a robust global platform designed to power complex digital distribution infrastructure through a unified suite of solutions, including connectivity APIs, marketplace ecosystems, and payment processing networks. As a Technical Lead, you will serve as the core architect driving our engineering excellence. Positioning yourself at the heart of our cross-functional development squads, you will ensure our architectural decisions today seamlessly support the massive transactional scale of tomorrow.

This position is tailored for a highly technical "builder-leader" who thrives on engineering complexity and wants complete ownership of the technical roadmap. You will be responsible for defining the execution strategy ("the how") behind every feature, ensuring that our current platform infrastructure is resilient, scalable, and architecturally prepared for the integration of decentralized/on-chain logic down the pipeline.

Core Responsibilities

• Architectural Ownership: Formulate and own the end-to-end technical architecture; directly recommend and decide on system designs, technology stacks, and integration patterns from scratch with a focus on long-term maintainability and scalability.

• Technical Governance: Provide strategic architectural recommendations and technical direction across the broader engineering department; review engineering designs, flag systemic risks early, and guarantee alignment with platform scalability standards.

• Engineering Standards: Establish and champion the foundational engineering benchmarks for code quality, testing methodologies, and documentation; run high-bar code reviews adopted across the development squads.

• Core Infrastructure Development: Architect and build the core data and event infrastructure capable of handling real-time, high-volume distribution and transaction processing, prioritizing throughput, fault tolerance, and data integrity.

• Security & Compliance: Embed robust security frameworks and compliance best practices directly into system designs and development workflows from day one.

• Mentorship & Talent Growth: Mentor engineers across all seniorities, identify and mitigate technical debt early, lead crucial code refactoring initiatives, and participate in technical interviews to scale a high-performing engineering team.

• Cross-Functional Collaboration: Partner closely with Product Managers and UI/UX Designers to translate business requirements into technical specifications and actionable engineering roadmaps; surface technical constraints and opportunities to inform product strategy.

• System Reliability: Monitor and maintain the reliability and performance benchmarks of production systems; spearhead root cause analysis (RCA) for critical incidents and implement permanent preventative engineering solutions.

Minimum Qualifications

• Experience: 8+ years of professional experience in Full-Stack Software Engineering, with a minimum of 2 years serving in a Technical Lead or Team Lead capacity within a fast-paced B2B SaaS or Fintech environment.

• First-Principles Thinking: Proven capability to architect scalable systems from the ground up, selecting programming languages, frameworks, data stores, and infrastructure patterns derived from first principles.

• Distributed Systems: Deep domain expertise in distributed systems and event-driven architectures (including real-time streaming, message queuing, and asynchronous processing), with the technical judgment to know exactly when their implementation is warranted.

• Database Engineering: Strong command of database design and optimization across both relational (SQL) and document/NoSQL models, including advanced schema design, indexing, query performance tuning, and scaling strategies.

• API Scalability: A proven track record of designing, developing, and shipping production-grade, scalable APIs and microservices capable of handling high-volume transaction traffic.

• Technical Leadership: Demonstrated ability to lead technical design sessions, drive architectural decision-making, and mentor senior and mid-level engineers.

Preferred Qualifications (Nice-to-Have)

• Future-Facing Tech: Hands-on experience with AI/LLM and machine learning systems, with a documented track record of integrating intelligent workflows, automation, and AI features across a platform.

• Cloud & DevOps: Direct experience managing cloud infrastructure (e.g., AWS containers/orchestration, serverless architectures, managed databases) and building robust CI/CD pipelines from scratch.

• Advanced Architecture: Familiarity with Domain-Driven Design (DDD) and Clean Architecture principles to manage highly complex business logic.

• Domain Background: Prior engineering background in distribution networks, digital marketplaces, payment processing, or heavy connectivity/API platforms.
