About The Position

We're looking for a Senior Software Engineer to help design, build, and evolve large-scale backend systems used by real customers in production. In this role, you'll be trusted to think at the system and architecture level, design critical backend components, and implement large portions of those designs while guiding other developers through execution.

Requirements

• 5+ years of professional software engineering or architectural experience (or equivalent depth).
• A proven track record of building backend systems from scratch that were launched into production, used by real users, and were supported and evolved over time.
• Experience designing and supporting APIs or backend systems at scale.
• Strong systems thinking — you can reason about performance, failure modes, scaling, and long-term maintainability.
• Experience working in startup or startup-like environments, or owning major systems within larger companies.
• Comfort working autonomously and making high-impact technical decisions.
• Proficient in AI-assisted development tools and workflows (e.g., Copilot, ChatGPT, code-generation and review tools) to improve productivity, code quality, and system design.

Nice To Haves

• Python experience is a plus, but not required.
• Experience redesigning or evolving legacy systems.
• Background in data-heavy systems (crawlers, feeds, ingestion pipelines, analytics backends).
• Infrastructure or scaling experience (high-throughput systems, reliability, performance tuning).
• Prior experience mentoring senior or mid-level developers.

Responsibilities

• Design, implement, and evolve backend systems that power data-heavy, production products.
• Lead architectural improvements to existing systems (e.g., redesigning market feeds, crawlers, APIs, or data pipelines).
• Build systems from scratch that go into production, are used by real users, and are maintained over time.
• Take ownership of major backend initiatives from design, implementation, rollout to long-term support.
• Write and maintain scalable APIs and backend services used at meaningful scale.
• Help break down complex designs into executable components and delegate effectively when working with other developers.
• Support and improve live production systems, ensuring reliability, performance, and maintainability.
• Collaborate closely with leadership and senior engineers on technical direction.
• Mentor other developers through code reviews, design discussions, and best practices.

• Fully Remote Work – Work from anywhere with a reliable internet connection
• Healthcare Coverage – We provide health benefits for you and your family's well-being
• Leave Days, Vacation Time, and Paid Holidays – Recharge and take the time you need
• Equipment Funds – Get support to set up or upgrade your home office
