Founded in 2019, we build an end-to-end platform for developing, training, and deploying AI systems-designed to take ideas from research to production with less friction.\nThrough our merger with Voltage Park, a neocloud and AI Factory, Lightning AI combines developer-first software with cost-efficient, large-scale compute. Teams get the tools they need for experimentation, training, and production inference, with security, observability, and control built in.\nWe serve solo researchers, startups, and large enterprises. Lightning AI operates globally with offices in New York City, San Francisco, Seattle, and London, and is backed by Coatue, Index Ventures, Bain Capital Ventures, and Firstminute.\nThe Way We Work\nThe people who thrive here are builders who move fast, communicate openly, take ownership, and continuously improve themselves, their teams, and our company. Here's what that looks like in practice:\nMove with Urgency: We move quickly, make thoughtful decisions, and keep momentum. We value action over perfection and learn by shipping.\nTake Ownership: We own outcomes, not just our individual work. We make decisions that move the company forward and follow through.\nCommunicate Openly: We communicate directly, seek to understand, and create clarity for others. Honest conversations help us move faster together.\nBuild Great Teams: We lead by example, empower others, and create healthy teams where people can do their best work.\nRaise the Bar: We're always improving ourselves. We learn from feedback, consistently challenge ourselves to grow, and focus on the work that matters most.\nThink Long-Term: We design for what's next. We create scalable systems, simplify complexity, and use AI and automation to amplify our impact.\nWhat We're Looking For\nThe Agents team at Lightning AI is building the infrastructure that powers the next generation of AI applications. As AI agents move from prototypes to production, developers need reliable systems for orchestrating workflows, coordinating models, executing tools, and managing long-running state. Our goal is to provide the platform and abstractions that make building production-ready agentic applications as simple as deploying any modern software service.\nWe're looking for a Senior Software Engineer to help design and build the backend systems that power Lightning AI's agent platform. You'll work on orchestration frameworks, tool execution, workflow management, memory and state handling, and developer-facing APIs that enable customers to build sophisticated AI applications with confidence.\nYou'll partner closely with engineers across Core Platform, Training & Experimentation, Sandboxes, and Optimized Compute to deliver platform capabilities that are reliable, scalable, and intuitive for developers.\nThis role is based in one of our San Francisco, NYC, or London office hubs, with a minimum of 2 in-office days per week and occasional team and company offsites. We are not able to provide visa sponsorship for this position at this time.\nWhat You’ll Do\nDesign and build backend services that power AI agent orchestration and execution.\nDevelop scalable APIs and platform capabilities for tool use, workflow orchestration, memory, and state management.\nBuild reliable infrastructure that enables long-running, distributed AI workflows.\nPartner with product, research, and platform engineering teams to bring new agent capabilities into production.\nImprove platform reliability, observability, and performance as customer workloads continue to scale.\nEvaluate and strengthen technical architecture, engineering processes, and developer tooling.\nMaintain high standards for software quality through testing, automation, continuous delivery, and proactive management of technical debt.\nMentor engineers on system design, distributed systems, and backend engineering best practices\nWhat You’ll Need\nExtensive experience building scalable backend systems using Go, Python, Rust, or similar languages.\nStrong understanding of distributed systems, asynchronous processing, APIs, and cloud-native application architecture.\nExperience designing and operating production services at scale.\nHands-on experience building backend platforms, developer tools, or infrastructure products.\nFamiliarity with cloud platforms such as AWS, GCP, or Azure and container technologies including Docker and Kubernetes.\nProven ability to take ownership of large technical initiatives from architecture through production.\nCommitment to software quality, automated testing, observability, and continuous delivery.\nStrong communication skills and the ability to collaborate effectively across engineering, product, research, and design teams.\nAbility to thrive in fast-moving, ambiguous environments while balancing technical excellence with product impact.\nCompensation\nWe are committed to offering competitive compensation that reflects the value each team member brings to our mission. Final offers are based on factors such as experience, skills, geographic location, and role expectations. In addition to base salary, our total rewards package for eligible roles includes a discretionary bonus, a meaningful equity component, and comprehensive benefits.\nThe anticipated annual base salary range for this role is:\n$180,000—$250,000 USD\nBenefits and Perks\nWe offer a comprehensive and competitive benefits package designed to support our employees’ health, well-being, and long-term success:\nComprehensive Health Coverage: Medical, dental, and vision coverage for employees and eligible dependents.\nMeaningful Equity: RSUs that give employees a stake in the company's long-term success.\n Retirement Savings: 401(k) matching (U.S.) and pension contributions (U.K.).\nFlexible Time Off: Unlimited PTO, company holidays, and floating holidays to support work-life balance.\nCompany-Wide Winter Break: Two weeks of company closure each winter to disconnect and recharge.\nPaid Parental & Family Leave: Paid leave to support you and your family through life's important moments.\nProfessional Development: Annual learning and development allowance to support your professional growth.\nWellness Benefits: Wellness and work-from-home stipends to support your physical and mental well-being.\nSabbatical Program: Four weeks of paid sabbatical leave after four years of service.\nFlexible Work: Flexible schedules and a hybrid work model for our office-based teams.\n In-Office Meals: Complimentary meals at our office hubs.\nBenefits may vary by location, team, and role.\nAt Lightning AI, we are committed to fostering an inclusive and diverse workplace. We believe that diverse teams drive innovation and create better products. We provide equal employment opportunities to all employees and applicants without regard to race, color, religion, gender, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other protected characteristic. We are dedicated to building a culture where everyone can thrive and contribute to their fullest potential.","description_format":"text","description_chars":7092,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity","Flexible schedule","Flexible time off","Hybrid work","Office meals","Parental leave","Professional development","Unlimited PTO"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"},{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["MLOps","AI Compute & Inference","AI Development Tools"],"lifecycle":[{"event":"open","at":"2026-08-07T21:58:28Z"}],"visa":[],"liveness":{"score":36,"band":"fade","label":"Fading","p_open":1,"p_active":0.823,"p_room":0.44,"age_days":69,"expected_fill_days":63,"reasons":["conf:1","velocity","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/lightning-ai-senior-software-engineer-agents","json_url":"https://alion.io/job/lightning-ai-senior-software-engineer-agents.json","meta":{"generated_at":"2026-10-17T04:23:46Z","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":5750,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":9002},"rest":"https://alion.io/mcp/rest/get_company?id=9002"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flightning-ai-senior-software-engineer-agents"},{"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%2Flightning-ai-senior-software-engineer-agents"},{"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%2Flightning-ai-senior-software-engineer-agents"},{"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/lightning-ai-senior-software-engineer-agents\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flightning-ai-senior-software-engineer-agents"}]}
