Senior Full Stack Developer, Agentic Engineering

FullBloom is hiring a Senior Full-Stack Developer to build staff-facing applications, APIs, and data services for Catapult Learning and SESI Schools. The role owns features end to end using AI coding agents and helps establish the team's agentic development pipeline, quality controls, and engineering practices.

Responsibilities:

• Agent-first development: Use AI coding agents (e.g., Claude Code) as the primary way to plan, implement, test, and refactor code, while staying accountable for every line that ships
• Judging agent output: Treat review and validation as the core of the job: catch defects in code that looks correct, decide which changes need closer human review, and own what merges
• Requirements to architecture: Work directly with product partners and stakeholders to turn lightweight briefs into agent-ready specs, technical designs, data flows, and acceptance criteria
• Proof-of-concept development: Prototype quickly to test feasibility, show value, and settle design questions before committing to a full build
• Short, experimental cycles: Build end-to-end working skeletons first (Simple, Lovable, Complete), apply YAGNI to keep AI-generated scope in check, and throw away work that doesn't earn its place
• Full-stack ownership: Own features end to end across front-end interfaces, APIs, back-end services, data stores, infrastructure as code, and deployment pipelines
• Integrations and data services: Build and maintain integrations with identity providers, rostering and student information systems, internal APIs, and shared data platforms
• Rebuilding legacy capabilities: Use agents to read existing systems well enough to extract their business rules, data, and edge cases, then rebuild those capabilities one at a time on the new stack
• Context and standards: Write and maintain the artifacts agents work from, including repository instruction files (CLAUDE.md/AGENTS.md), AI-readable coding standards, architecture decision records, and a shared skills and prompt library
• Tooling and integrations: Configure agent tooling, permissions, and MCP integrations (e.g., GitHub, Jira, browser automation) so agents can work safely in our repositories and environments
• Environments and DevOps: Own the squad's DevOps alongside the code, including preview environments, safe test data with student information removed, and deployment pipelines, so agents can build and verify changes without touching production data
• Quality gates: Strengthen automated tests, CI checks, and AI-assisted code review so agent output meets the same bar as human code before it merge
• Verification loops: Build feedback loops that let agents check their own work, such as end-to-end tests and headless browser checks, while keeping independently written tests for high-risk areas
• Governance: Apply guardrails for secrets, data access, and student data, and keep agent-driven work aligned with SOC 2 change-management and SDLC controls
• Mentoring: Mentor early-career engineers who join the squad, with a focus on the fundamentals and review habits that agents don't teach
• Codifying practice: Turn what works into repeatable playbooks, templates, and skills that new squad members and FullBloom's other engineering teams can reuse, and log friction points so the pipeline improves with each project
• Working across roles: Work closely with product and design partners in a model where roles blur, including designers submitting changes against working code
• Measuring outcomes: Track delivery and quality signals such as lead time, rework, escaped defects, and change-failure rate, not tool adoption alone
• Review human- and agent-written code for correctness, security, maintainability, and performance
• Monitor, troubleshoot, and resolve production issues, and take part in incident response and post-incident reviews
• Communicate scope, timelines, and trade-offs clearly to technical and non-technical colleagues
• Promote usability, accessibility, and security best practices
• Other duties as assigned

Requirements:

• Bachelor's degree in Computer Science or a related field and 5+ years of relevant work experience, or equivalent experience
• Daily, hands-on use of AI coding agents (e.g., Claude Code, Codex, Cursor) to build production software, with concrete examples of how it changed your workflow and results
• Working knowledge of what makes agents effective: context management, task decomposition, clear specs and prompts, and rigorous verification of agent output
• Demonstrated judgment reviewing agent output: you can find and explain problems in code that looks correct, and you know when a change needs closer human review
• Strong product sense: you can turn an ambiguous problem into a clear, well-scoped spec and push back on features that aren't needed
• Strong proficiency in TypeScript/JavaScript, React, HTML, and CSS
• Experience designing and building REST APIs and back-end services
• Strong working knowledge of relational databases (e.g., PostgreSQL), including data modeling, query writing, and performance tuning
• Experience with cloud hosting, serverless technologies, and infrastructure as code (e.g., AWS with Terraform or CDK)
• Proficiency in writing and automating unit, integration, and end-to-end tests
• Experience with CI/CD pipelines such as GitHub Actions, and owning your own environments and deployments
• Git and version control expertise, including pull-request-based review workflows
• Strong knowledge of cross-browser, cross-platform, and cross-devicecompatibility
• Experience building accessible applications that meet WCAG and ADA requirements
• A track record of owning features end to end and mentoring other engineers
• Clear written communication, including specs and technical designs that both people and agents can work from
• Comfort working in short, experimental cycles and discarding work thatdoesn't pan out
• Experience leading or contributing to a team's adoption of agentic development practices
• Experience building agent tooling, such as MCP servers, custom skills orsubagents, or CI-integrated agent workflows (e.g., ticket-to-pull-request automation)
• Experience building LLM-powered or multi-agent features with frameworks such as the Claude Agent SDK, LangGraph, or Google ADK, including tooldesign, orchestration, and memory
• Experience rebuilding legacy applications on modern stacks, including extracting business rules from systems you didn't build
• Experience as an early member of a new team or product
• Experience designing data-heavy applications that handle large datasets with low latency and high reliability
• Experience building education technology, especially for PreK-12 schools and districts
• Experience integrating SSO and identity providers, including SAML or OIDC
• Experience with education data integrations such as SIS rostering (e.g.,OneRoster, Clever) or LMS platforms
• Experience building search or analytics features with Elasticsearch or similar engines
• Familiarity with UX and HCI principles and design tools such as Figma
• Experience working under student-data privacy requirements (FERPA, COPPA)or SOC 2 controls
