The Mid Level Back End Developer typically has more experience and handles complex tasks independently, while the Junior Back End Developer is in the early stages of their career, focusing on learning and assisting with basic tasks.

What are the key skills and qualifications needed to thrive as a mid level back end developer, and why are they important?

To thrive as a Mid Level Back End Developer, you need proficiency in server-side languages (such as Java, Python, or Node.js), database management, and a solid understanding of API design and data structures, usually supported by a relevant degree or equivalent experience. Familiarity with frameworks (like Spring Boot or Express), version control systems (such as Git), and containerization tools (like Docker) is typically expected. Strong problem-solving abilities, communication skills, and the ability to collaborate effectively with cross-functional teams make you stand out in this role. These skills ensure robust, scalable backend systems and efficient teamwork, both of which are vital for delivering high-quality software products.

What are the typical responsibilities and collaboration points for a mid level back end developer within a software development team?

As a Mid Level Back End Developer, your daily responsibilities often include designing, implementing, and maintaining server-side logic, APIs, and database schemas. You will regularly collaborate with front-end developers to ensure seamless data exchange and with DevOps engineers to optimize deployment pipelines. Mid level roles also involve code reviews, troubleshooting, and contributing to architectural decisions. This position provides opportunities to mentor junior developers and work closely with product managers to translate business requirements into technical solutions.

What is a mid level back end developer?

Mid Level Back End Developers are software professionals who specialize in server-side development, typically with 2-5 years of experience. They design, build, and maintain the logic, databases, and APIs that power web and mobile applications. Unlike entry-level developers, they are expected to work independently on complex features, contribute to architectural decisions, and collaborate closely with front end developers. Their work ensures that applications are scalable, secure, and efficient, making them an essential part of any software development team.

Job description

We're looking for a senior or staff-level backend engineer to own and evolve the core systems that power Lighthouse.

Our backend is Python and TypeScript, PostgreSQL, GraphQL, and serverless compute, with LLMs woven throughout.

This role is focused on making our backend faster, more reliable, and ready to scale. The problems ahead of us:

  • Designing and building agentic systems: autonomous, multi-step workflows that draft legal documents, review cases, and orchestrate complex processes with minimal human input.

  • Improving backend security: tightening auth, moving toward proper environment isolation, hardening our database access patterns.

  • Scaling our API layer. The customer-facing GraphQL API has grown organically and needs better structure, performance, and maintainability.

  • Building robust data pipelines and integrations across Slack, Linear, HubSpot, Front, and other external services.

  • Strengthening our document ingestion and generation pipelines, the systems that turn messy inputs into filing-ready legal output.

You might be a good fit if:

  • You have 5+ years building and operating production backend systems: APIs, databases, async job processing, event-driven architectures.

  • You're strong in Python/Typescript and have experience building scalable, complex backend systems. Experience with PostgreSQL, async Python, and event-driven architectures is a plus.

  • You've built (or want to build) agentic systems and LLM-powered features. We're automating complex legal workflows with AI and need people who want to push that forward.

  • You think carefully about system design: service boundaries, data modeling, failure modes, observability.

  • You have high agency, especially for independent research and problem-solving.

  • You've dealt with the messy realities of scaling systems: migrations, dual-writes, feature flags, legacy code removal.

Culture

  • Our client is an engineering-led company. We get to pick/veto what we build.

  • We spend a considerable chunk of time with users (the legal operations team, or customers) to find and pick what to build. Some projects our team has worked on include:

    • A real-time, collaborative text editor using CRDTs

    • An LLM agent framework with tools for case automation

    • A custom PDF compilation pipeline on serverless infrastructure

    • Autonomous letter-drafting agents powered by LLMs

  • We ship multiple times a day, with a preference for testing ideas out quickly and polishing over time.

Pay and Benefits

  • We sponsor visas, obviously.

  • Competitive base and equity, scales with experience.

  • Competitive medical, dental, and vision benefits.

  • 401k with a 3% company match.

  • Equipment/office stipend.

  • Annual team off-site in cool places.

  • In person in San Francisco or New York.
