About the Role

Staff Software Engineer is an individual contributor role with technical leadership and significant ownership across the full stack, including web applications and backend systems. This role involves hands-on engineering, shaping architecture, setting technical direction, and enabling engineers across teams to deliver effectively. The engineer will contribute to defining technical foundations, identifying high-impact challenges, and turning ambiguous problems into clear plans. Impact extends beyond systems built, including leading complex initiatives, mentoring engineers, and establishing practices to improve engineering quality and effectiveness. The role also involves shaping the approach to AI-assisted development and building systems capable of handling millions of events daily.

Responsibilities

Set technical direction for major areas of the Markets platform, aligning architectural decisions with product strategy and guiding their implementation across teams.
Lead the design and delivery of complex, scalable systems and customer experiences, contributing hands-on in React, Next.js, and TypeScript or backend services in Go, while making meaningful contributions across the stack.
Identify and resolve ambiguous engineering problems spanning team or system boundaries, turning them into clear proposals, delivery plans, and measurable outcomes.
Own critical initiatives end-to-end, from discovery and technical specifications through implementation, instrumentation, deployment, monitoring, and iteration.
Partner with product, design, platform, and infrastructure teams to make informed tradeoffs across customer experience, accessibility, performance, security, reliability, and delivery speed.
Define architecture and integration patterns for frontend applications, backend APIs, and event-driven systems, with particular attention to correctness in markets, orders, and transactions.
Guide the design of experimentation capabilities, including feature flags and A/B tests, so teams can validate ideas quickly and safely.
Anticipate scaling constraints, reliability risks, and technical debt; build alignment on pragmatic improvements and drive them through to completion.
Raise engineering standards through design reviews, code reviews, testing strategies, observability, and safe deployment practices.
Mentor engineers and develop technical leaders, helping teams make sound decisions and solve problems independently.
Establish and evolve standards for AI-assisted development, including appropriate use cases, review expectations, security safeguards, and validation strategies.
Measure and improve engineering effectiveness, sharing tools and practices that increase delivery speed without compromising quality.
Lead through influence in an early-stage product environment, creating clarity, unblocking teams, and establishing ways of working that support growth.

Requirements

Substantial experience building and operating highly scalable production systems, with demonstrated impact at Staff level or equivalent scope, including technical leadership across teams or major platform areas.
Deep expertise in either user-facing web applications built with JavaScript/TypeScript and React or backend services built with languages such as Go, Java, or Python, alongside the ability to reason across the full stack.
A track record of setting technical direction and delivering complex initiatives from ambiguous requirements through to measurable production outcomes.
Strong architectural judgment, including the ability to assess tradeoffs, establish clear system boundaries, and evolve systems as product requirements and scale change.
Experience shaping React architecture, component-driven development, and modern state management using tools such as Next.js, TanStack Query, Tailwind, or Zustand; or deep backend experience with data modeling, distributed systems, and event-driven architecture using technologies such as Postgres and Kafka/PubSub.
Deep knowledge of your primary language's features, idioms, and best practices, with experience establishing standards adopted beyond your immediate team.
Strong understanding of performance, reliability, and security, including responsive design and accessibility on the frontend or scalability, observability, data integrity, and failure handling on the backend.
Experience defining API contracts and collaborating across product, platform, and infrastructure teams to deliver reliable systems.
Experience shaping CI/CD pipelines, testing strategies, and safe deployment practices across services or applications.
Demonstrated ability to lead through influence, build alignment across teams, and communicate technical decisions clearly to engineers and non-technical stakeholders.
A track record of mentoring engineers, strengthening technical decision-making, and increasing the effectiveness of others.
Demonstrated experience using AI tools such as Claude Code, Codex, Cursor, or Copilot to ship production code, with sound judgment about their limitations and appropriate validation.
Specific examples of improving development workflows, with evidence of their impact on delivery speed, quality, or engineering productivity.
A team-first approach, with the judgment to move between strategic technical work and hands-on delivery according to the needs of the product.
Ability to create clarity in a high-growth environment where priorities evolve and decisions must be made quickly.
Strong cross-functional collaboration skills, including experience aligning teams and navigating dependencies within large enterprise environments.
Previous experience shaping technical foundations in early-stage or high-growth startup environments.
Experience with real-money transaction systems, including financial correctness, auditability, and regulatory requirements.
Experience developing technical roadmaps or leading architectural changes adopted across multiple teams.
Background in building developer tools or improving engineering productivity at scale.
Experience establishing AI-assisted engineering practices across teams.
Contributions to open-source projects or the technical community.
BSc in Computer Science or a related field.
