Its technology has already analyzed more than 5 million production calls and tested over 10,000 voice agents, including deployments within regulated industries such as financial services and healthcare.\nThe engineering team is now entering a critical stage: building its own database and scaling the platform from thousands toward 100,000+ concurrent calls, with a longer-term path to one million.\nWe are looking for a highly hands-on Staff-level engineer who can lead database and backend architecture, build complex systems end-to-end and operate effectively within a small, fast-moving startup team.\nWhat you will work on\nLead the design and development of a purpose-built database and indexing architecture.\n\nScale the simulation engine toward 100,000+ concurrent voice calls.\n\nBuild high-throughput ingestion, storage and query infrastructure.\n\nDevelop systems for processing call recordings, transcripts, metadata and evaluation results.\n\nImprove reliability, latency and performance across the platform’s highest-load paths.\n\nBuild infrastructure supporting AI red-teaming and production monitoring.\n\nMake key architectural decisions and turn them into working prototypes quickly.\n\nOwn projects end-to-end, from an ambiguous problem to production deployment.\n\nHelp establish the technical direction for a system that can become a long-term company moat.\n\nWhat we are looking for\nAt least 5 years of production backend engineering experience.\n\nHands-on experience building or core-contributing to a database, queue, indexing layer or large-scale data system.\n\nStrong understanding of storage, ingestion and query paths.\n\nExperience designing and scaling distributed systems under real production load.\n\nAbility to discuss previous systems quantitatively, including throughput, data volume, latency, SLAs, bottlenecks and failure modes.\n\nEvidence of personal ownership: you personally designed and built meaningful parts of the system.\n\nAbility to build complete systems rather than work only on narrowly scoped components.\n\nStrong architectural judgment combined with a bias toward shipping and iteration.\n\nExperience operating without extensive process, detailed specifications or organizational scaffolding.\n\nClear written and verbal English communication.\n\nDaily use of AI coding tools such as Claude Code, Codex or Cursor, together with a practical understanding of their strengths and trade-offs.\n\nAvailability for substantial daily overlap with US working hours. For candidates based in Europe, this means working during the late afternoon and part of the evening.\n\nWe care more about technical depth, judgment and measurable impact than a specific title, programming language or number of years in one particular stack.\nStrong advantages\nExperience as a founding engineer, first or second engineer, or one of the first ten hires at a startup.\n\nExperience within a modern database, data infrastructure or observability company.\n\nOpen-source contributions to projects such as PostgreSQL, ClickHouse, Redis, Kafka, Temporal, LiveKit or similar infrastructure.\n\nProduction experience with Scala, Rust, Haskell or another systems-oriented language.\n\nExperience with voice technology, telephony, WebRTC, audio pipelines or real-time communications.\n\nExperience building systems processing gigabytes or terabytes of data per day.\n\nHands-on experience with PostgreSQL, Kafka, Redis, ClickHouse, Temporal or custom indexing systems.\n\nPersonal systems, database or open-source projects built outside of your primary employment.\n\nVoice and telephony experience is not required. The company would rather teach the voice domain to an exceptional systems engineer than try to teach deep systems engineering to a domain specialist.\nHow the team operates\nThis is a small, senior and highly technical engineering team. The founder remains hands-on and writes production code.\nThe team ships multiple times per day and values a simple operating model:\nDefine the problem, identify the options, select the cheapest useful experiment, assign ownership, ship and iterate.\nThis environment is best suited to engineers who enjoy autonomy, ambiguity and direct responsibility. It will not be a strong match for someone who requires several months of onboarding, extensive organizational structure or a large support team before contributing.\nThe role can remain a highly technical individual-contributor position. Management responsibilities are available in the future but are not required.\nLocation\nThe position is remote and open to candidates based in:\nEurope\n\nCanada\n\nUnited States\n\nOther locations offering reasonable US time-zone overlap\n\nRegular and meaningful overlap with US working hours is mandatory. Candidates based in Europe should be comfortable working later hours to collaborate with the US team.\nThe company also has office locations in Austin and San Francisco for candidates who prefer a hybrid environment.\nCompensation\nBase salary: $160,000–$240,000 USD\n\nEquity: 0.2%–1%\n\nThe final offer will depend on seniority, location, experience and the level of technical ownership the candidate can take on.\nInterview process\nThe complete process typically takes approximately two weeks:\n15-minute introductory and culture conversation.\n\nOpen-book backend coding interview using the candidate’s preferred AI tools.\n\nSystem design interview.\n\nSecond system design interview.\n\nOptional paid two-to-three-day work trial if additional mutual validation is needed.\n\nReference checks and offer.\n\nInterested?\nApply with your CV or LinkedIn profile.\nPlease include one short example of the most complex database, queue, indexing or large-scale backend system you personally built or owned. If possible, mention its scale and your individual contribution.\nTech stack\nTypeScript\nNode.js\nDistributed systems\nPostgreSQL\nKafka\nAWS\nScala","description_format":"text","description_chars":6287,"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":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"},{"name":"Germany","iso":"DE","kind":"region"},{"name":"France","iso":"FR","kind":"region"},{"name":"United Kingdom","iso":"GB","kind":"region"},{"name":"Austria","iso":"AT","kind":"region"},{"name":"Belgium","iso":"BE","kind":"region"},{"name":"Bulgaria","iso":"BG","kind":"region"},{"name":"Croatia","iso":"HR","kind":"region"},{"name":"Czech Republic","iso":"CZ","kind":"region"},{"name":"Denmark","iso":"DK","kind":"region"},{"name":"Finland","iso":"FI","kind":"region"},{"name":"Hungary","iso":"HU","kind":"region"},{"name":"Ireland","iso":"IE","kind":"region"},{"name":"Italy","iso":"IT","kind":"region"},{"name":"Netherlands","iso":"NL","kind":"region"},{"name":"Norway","iso":"NO","kind":"region"},{"name":"Poland","iso":"PL","kind":"region"},{"name":"Romania","iso":"RO","kind":"region"},{"name":"Spain","iso":"ES","kind":"region"},{"name":"Sweden","iso":"SE","kind":"region"},{"name":"Switzerland","iso":"CH","kind":"region"},{"name":"Estonia","iso":"EE","kind":"region"},{"name":"Greece","iso":"GR","kind":"region"},{"name":"Iceland","iso":"IS","kind":"region"},{"name":"Latvia","iso":"LV","kind":"region"},{"name":"Liechtenstein","iso":"LI","kind":"region"},{"name":"Lithuania","iso":"LT","kind":"region"},{"name":"Luxembourg","iso":"LU","kind":"region"},{"name":"Malta","iso":"MT","kind":"region"},{"name":"Portugal","iso":"PT","kind":"region"},{"name":"Slovakia","iso":"SK","kind":"region"},{"name":"Slovenia","iso":"SI","kind":"region"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-08T22:59:03Z"}],"visa":[],"liveness":{"score":70,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.739,"p_room":0.945,"age_days":9,"expected_fill_days":26,"reasons":["seen:9","win:mid"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":20000,"is_top_pay":false},"html_url":"https://alion.io/job/talentica-software-staff-backend-database-infrastructure-engineer","json_url":"https://alion.io/job/talentica-software-staff-backend-database-infrastructure-engineer.json","meta":{"generated_at":"2026-10-16T23:50:57Z","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":5970,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":7833},"rest":"https://alion.io/mcp/rest/get_company?id=7833"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftalentica-software-staff-backend-database-infrastructure-engineer"},{"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%2Ftalentica-software-staff-backend-database-infrastructure-engineer"},{"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%2Ftalentica-software-staff-backend-database-infrastructure-engineer"},{"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/talentica-software-staff-backend-database-infrastructure-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftalentica-software-staff-backend-database-infrastructure-engineer"}]}
