We're a vertical fintech and SaaS platform unlocking more ways to give - cash, stock, crypto, and beyond - through a beautifully designed ecosystem built for high-impact churches, nonprofits, and mission-driven institutions.\nBacked by Uncork Capital, Craft Ventures, Salesforce Ventures, R7, and WIF (one of the largest lenders to faith and philanthropic organizations in the country), we're building the infrastructure that makes generosity frictionless at scale.\nOur Founding Principles\nOverflow was founded on the belief that generosity transforms people and communities. Inspired by Proverbs 11:24 - \"The world of the generous gets larger and larger\" - we operate with integrity, stewardship, service, and excellence.\nHow We Work\nOverflow operates with a flexible work model. While there is no company-wide in-office requirement, some teams may establish in-person collaboration rhythms based on their function, goals, and team needs.\nWe maintain offices in Los Gatos, CA and Birmingham, AL for team collaboration, coworking, meetings, and intentional in-person connection.\nAbout the Role\nAs a Senior Fullstack Engineer on our Growth team, you will be the technical engine behind our Product-Led Growth (PLG) initiatives. Your work will directly impact how organizations discover, adopt, and expand their use of Overflow.\nYou will design and build the critical pathways that allow our customers to scale their generosity effortlessly. This includes architecting seamless self-service onboarding flows, creating frictionless plan upgrade paths, and standing up high-converting checkout experiences across new e-commerce touchpoints. You will sit at the intersection of engineering, product, and revenue, turning complex business requirements into intuitive, reliable, and scalable product features.\nWhat You Will Do\nDrive Product-Led Growth: Architect and build robust, end-to-end features that enable intuitive customer self-onboarding, seamless subscription plan upgrades, and highly optimized e-commerce checkout flows.\n\nFull-Stack Ownership: Own complete features from database schema and RESTful API design (Node.js) through to a polished, highly responsive frontend implementation (React/TypeScript).\n\nEngineering Excellence: Write clean, well-tested, and maintainable code, actively contributing to engineering standards and rigorous code reviews.\n\nCross-Functional Collaboration: Partner closely with Product, Design, and Data to iterate quickly, run experiments (A/B tests), and deliver high-quality user experiences that drive conversion.\n\nArchitectural Strategy: Identify technical debt and contribute to architectural improvements that enhance the reliability, scalability, and speed of our Growth product surfaces.\n\nMentorship & Reliability: Mentor junior engineers, help elevate the team's technical capabilities, and participate in on-call rotations to ensure the high availability of our systems.\n\nWhat You Should Have\nCore Experience: 5+ years of fullstack software engineering experience\n\nTechnical Stack: Strong proficiency in React, TypeScript, and Node.js (or similar modern backend technologies).\n\nSystems Design: Deep experience designing and building scalable RESTful APIs and working with relational databases.\n\nGrowth Mindset: A strong product sense and an understanding of product-led growth mechanics, conversion funnels, and user-centric design.\n\nLeadership & Ownership: Demonstrated ability to lead technical initiatives, make sound architectural decisions, and operate with a strong accountability mindset.\n\nIt'd Be Nice If You Had\nE-commerce & Billing Experience: Hands-on experience integrating with billing and subscription platforms or building custom e-commerce checkout experiences.\n\nFintech Context: Experience in fintech, payments infrastructure, or donation platforms.\n\nStartup DNA: Experience at a Series B or growth-stage startup, thriving in a fast-paced, iterative environment.\n\nOur Compensation Philosophy\nThe base salary range for this position is $120k - $200k, based on Carta Total Compensation benchmarks for role, geography, and function. Total compensation may also include equity, performance-based bonuses (for eligible roles), and a comprehensive benefits package.\nBenefits & Perks\nCompetitive base salary with equity eligibility\n\nMedical, dental, and vision coverage for employees and dependents\n\nGenerous paid time off and company holidays\n\nPaid parental leave\n\n401(k) retirement plan\n\nDedicated mental health and therapy stipend to support personal well-being\n\nTeam retreats and intentional in-person gatherings throughout the year\n\nOverflow is proud to be an equal opportunity employer and is committed to building a diverse and inclusive team.","description_format":"text","description_chars":4821,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule","Parental leave","Retirement plans"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Commerce","Web Development Services","Digital Marketing"],"lifecycle":[{"event":"open","at":"2026-09-05T14:16:13Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.131,"p_room":0.28,"age_days":108,"expected_fill_days":7,"reasons":["conf:3","stale_co","ghost","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":{"stated_usd_annual":200000,"is_top_pay":true},"html_url":"https://alion.io/job/overflow-agency-senior-fullstack-engineer-growth","json_url":"https://alion.io/job/overflow-agency-senior-fullstack-engineer-growth.json","meta":{"generated_at":"2026-10-30T18:57:33Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":8216,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":116656},"rest":"https://alion.io/mcp/rest/get_company?id=116656"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Foverflow-agency-senior-fullstack-engineer-growth"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Foverflow-agency-senior-fullstack-engineer-growth"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Foverflow-agency-senior-fullstack-engineer-growth"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/overflow-agency-senior-fullstack-engineer-growth\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Foverflow-agency-senior-fullstack-engineer-growth"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":288803}},{"tool":"search_jobs","arguments":{"company":"overflow.agency","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":288803},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
