It's a hands-on, high-leverage role for someone who thrives on scope and ambiguity - you'll operate across team boundaries, raise the engineering bar for everyone around you, and stay close enough to the code to build the hardest parts yourself.\nWhat you'll drive\nThis is foundational work that scales R2 to the next level and reaches millions of users worldwide. You'll turn large, business-critical problems into architectures the whole org can execute against - work like:\nLarge-scale decomposition - breaking tightly-coupled systems into clearly-bounded domains along both service/application and data-ownership boundaries, defining the seams and sequencing migrations so we ship incrementally without freezing product delivery.\nEvent-driven systems and data lifecycle - designing event-driven architectures for things like moving stale data out of operational databases into cold storage, keeping transactional systems lean while preserving the retention, auditability, and recoverability guarantees a fintech demands.\nAgent infrastructure at scale - helping build the ecosystem where autonomous agents are deployed, discovered, and interact with our systems and each other at scale, with observability, policy, and security as first-class, non-negotiable properties.\nRequirements\n8+ years of engineering experience building API-driven services, with the appetite and ability to code on a daily basis.\nDeep expertise designing and constructing web services in REST and/or gRPC, from interface design through production operation.\nStrong track record with distributed architecture patterns, in particular microservices and monolith decomposition - you've done this at real scale, not just on a whiteboard.\nHands-on experience designing and implementing event-driven architectures.\nExperience with change data capture (CDC) - streaming changes out of operational databases (e.g., Postgres WAL / logical replication, Debezium, or equivalent) to power replication, event pipelines, and downstream analytics.\nHigh proficiency with observability across all three pillars - traces, metrics, and logs. Deep hands-on experience with OpenTelemetry for instrumentation, and with metrics systems (Prometheus and PromQL, or equivalent) for defining SLIs, dashboards, and alerting - and using that telemetry to actually drive decisions.\nSolid, demonstrable refactoring ability: you can restructure large, load-bearing codebases safely and incrementally.\nFluent with trunk-based development, feature flags, and continuous, low-risk delivery.\nStrong proficiency in Go (required). Additional experience with Java, Python, or Rust is a plus.\nExperience designing and implementing robust production data models using databases like PostgreSQL, DynamoDB, and/or Snowflake - including data lifecycle, retention, and archival concerns.\nSolid grasp of the OLTP-OLAP divide - designing transactional systems for low-latency operational workloads while feeding analytical stores (e.g. Snowflake) for reporting and analytics, and knowing where each belongs.\nExperience with containers (Docker, Docker Compose, Kubernetes).\nHands-on experience designing and operating full-text search (e.g. Elasticsearch/OpenSearch, or PostgreSQL full-text search) in production - indexing, relevance, and query performance at scale.\nProfessional working proficiency in both English and Spanish (required) - you'll collaborate across teams and markets in both languages daily.\nThe judgment and communication skills to influence technical direction across teams and align engineers and stakeholders around a shared plan.","description_format":"text","description_chars":3678,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false},{"language":"Spanish","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Recruiting & Staffing","IT Staffing & Staff Augmentation"],"lifecycle":[{"event":"open","at":"2026-07-17T00:00:00Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.623,"p_room":0.28,"age_days":98,"expected_fill_days":47,"reasons":["conf:7","velocity","win:tail","crowd:"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/marathon-talent-staff-software-engineer-r2","json_url":"https://alion.io/job/marathon-talent-staff-software-engineer-r2.json","meta":{"generated_at":"2026-10-23T10:24:18Z","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":15808,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":9282},"rest":"https://alion.io/mcp/rest/get_company?id=9282"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmarathon-talent-staff-software-engineer-r2"},{"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%2Fmarathon-talent-staff-software-engineer-r2"},{"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%2Fmarathon-talent-staff-software-engineer-r2"},{"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/marathon-talent-staff-software-engineer-r2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmarathon-talent-staff-software-engineer-r2"}]}
