As a Principal Frontend Engineer, you will be part of key engineering team within our engineering organization, responsible for the architectural vision, design, and implementation of our frontend systems. You will work closely with cross-functional teams, engineers at all levels, product managers, and UX designers, to deliver a world-class user experience for our SaaS platform. This role requires deep engineering skills in modern frontend technologies, strong leadership skills, and a strategic mindset to drive the evolution of our systems in alignment with business goals.
This isn't your typical, boring, web application, but a highly sophisticated, modern, SPA plus Node JS BFF, that pushes the boundaries of memory and computation in a browser requiring many components to be meticulously engineered for optimal performance. Challenges include use of web workers, algorithmic design/optimization, replication patterns, caching, async design, and the successful management of complexity. The system involves real-time collaborative document editing, requiring concurrency and distributed systems thinking. This role focuses on the most advanced and challenging aspects of this system in an environment of innovation and technical excellence.
Responsibilities:
- Complex web frontend SPA development and architecture.
- Design and implement concise, modular, cohesive, frontend and backend services in a distributed system context that are resilient, efficient, and reliable.
- Ensure automated tests are highly effective in terms of software quality, refactor flexibility, and integration/delivery/build speed.
- Design, refactor, implement, or work within micro-frontend SPA(s).
- Optimize builds for speed and deterministic dependency management.
- Concurrent and asynchronous software design/development.
- Advanced asynchronous and resilient network communications design and implementation.
- Software development on complex, but potentially irreducible algorithms or combinatorials.
- Understand the basics of determinism, complexity classes, and resource constraints.
- Find ways to reduce/decompose complex software components along appropriate boundaries.
Responsibilities (cont.):
- When apparently irreducible problems are encountered and they resist beneficial decomposition (np-ness), find ways to simplify through approximation theory and quantization.
- Extensive usage of all aspects of observability systems from experienced instrumentation of code to well-designed queries, dashboards, and alerts.
- Data driven optimization of latency, compute, memory, storage, and network traffic.
- Maintain awareness of production system performance, errors, and code usage.
- Communicate with clarity with diagrams, documentation, and presentations to other developers, dev teams, SREs, and management.
- Optimize build, deployment, and IaC provisioning pipelines.
- Rigorous analysis of escaped defects to determine corrective actions with depth of insight.
- Communicate clearly via software architecture, embedded docs, or o11y.
- Design and develop defensively to maintain or increase security going beyond OWASP and zero trust patterns by truly understanding the area of the system being worked on.
- Rigorous and proficient review and clear feedback on pull requests by team members.
- Keep up with relevant technologies, techniques, tools, and patterns.
- Ensure the software is as simple as possible, but not simpler.
- Build software with people. Product managers, other developers, SREs, junior engineers, senior engineers, and offshore. Construct software that matters!
- Constantly address technical debt. Shine a light on it, even when it hurts.
- Participate in the planning of technical engineering and product roadmaps.
- Plan, lead, or manage projects when called upon to do so while remaining hands on.
Qualifications:
- BS in Computer Science or equivalent work experience. Commitment to your development, the products you work on and the firm.
- 6-15+ years of experience designing and building frontend software applications
- Experience with secure coding standards and participation in systems security practices.
- Ability to explain complex topics to managers/directors, program/product managers
Non-negotiables:
- Strong Typescript/JavaScript/ECMAScript
- REACT (preferred), Angular, or other SPA frontend development tech stack
