It is a space where our brilliant team consequently brings technology change to the business world and instead of following known paths, we are creating a new one – a next-generation, fully personalized, and AI-driven customer experience.\nWe successfully deliver an all-in-one tool – Synerise. An ever-evolving behavioral data platform, enhanced by AI to generate outstanding ROI in more than 30 markets for industry leaders in Retail, Banking, eCommerce, Automotive, Insurance, and Telco, processing more than 150 billion transactions annually. However, we don’t limit ourselves solely to this solution. We’re building BaseModel – a foundation model for behavioral data embedded within a novel platform for enterprise Data Science teams, that is another step on our path to create innovation in AI and demonstrate its potential for the business world.\nHaving such great solutions, we are looking for a highly motivated Scala Engineer to join our brave and brilliant Synerise Team. See if you fit our diverse and dynamic environment, where we constantly evolve together with the growth of our clients.\nOur Backend Team works with Scala, Kafka, ElasticSearch, ScyllaDB, Azure, GCP, and Kubernetes. Distributed tracing (OpenTelemetry, Jaeger), structured logging, and rich metrics are core to how we build and operate services — not an afterthought. Both Backend and Frontend teams are supported by dedicated QA and Infrastructure teams. We like to experiment, and we have the environment to do it. We use AI coding assistants (Claude, Copilot) as a daily part of our workflow — not to replace engineering judgment, but to move faster on the parts that benefit from it.\nThe platform handles up to 28k API requests per second at peak with p95 latency under 100ms. You'd be joining the team responsible for event processing and analytics — the part of the platform that ingests, processes, and stores customer behavior events at scale, and powers the analytical capabilities our clients rely on. It's the data backbone the rest of the product is built on.\nYou'll be working on software that:\nIngests and processes high-volume streams of customer behavior events from online and offline commerce — peaks at 30k events per second.\n\nReliably stores and organizes event data for downstream analytics and querying.\n\nPowers the analytics module that turns raw events into insights for our clients.\n\nHas to stay reliable, ordered, and correct under load.\n\nRuns on a microservices architecture on Kubernetes.\n\nWhat will you do on a daily basis?\nDesign architecture and patterns for processing and storing high-volume datasets. \n\nBuild software with a strong focus on performance and optimization. \n\nTranslate complex functional and technical requirements into detailed designs. \n\nAnalyze large data stores and surface meaningful insights.\n\nWhat will make us a perfect match?\nStrong Scala skills, with production experience using an effect system (Cats Effect, ZIO, or Akka/Pekko) — we care more about depth of understanding than years on your CV. \n\nExperience designing or significantly contributing to event-driven systems in production — comfortable reasoning about ordering guarantees, idempotency, replay, and failure modes. \n\nStrong working knowledge of Apache Kafka — not just as a consumer API, but understanding partitioning, delivery guarantees, consumer groups, rebalance issues, and consumer lag. \n\nHands-on Kubernetes skills sufficient to independently diagnose pod issues, resource limits, HPA behavior, and networking. \n\nExperience with both SQL and NoSQL databases, with a clear sense of when each is the right tool. \n\nAbility to design for scale and growth — partitioning, sharding, tenant isolation, backpressure. \n\nStrong debugging and troubleshooting skills in distributed environments. \n\nWhat will convince us even more? \nSolid grasp of JVM internals — GC behavior, profiling, heap and thread dump analysis. \n\nExperience with observability: distributed tracing (OpenTelemetry, Jaeger), structured logging, metrics — for us this is core to daily work. \n\nExperience with microservices architecture, including awareness of common pitfalls (distributed transactions, eventual consistency, contract versioning). \n\nExperience working in a cloud environment (Azure / GCP) — our stack runs primarily on AKS. \n\nWhat can we provide for you?\nWork on a production-grade, large-scale system used by enterprise customers worldwide.\n\nReal technical challenges around performance, data volume, and distributed systems.\n\nOpportunities for continuous technical growth and deeper ownership over system design.\n\nSupport from experienced engineers and a strong engineering culture.\n\nInfluence on architectural and technical decisions within your team.\n\nTech stack\nScala\nZio\nAkka\nApache Kafka\nAzure\nAPI","description_format":"text","description_chars":4831,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Predictive Analytics","Recommendation Systems","Marketing & Sales AI","Retail & Commerce AI"],"lifecycle":[{"event":"open","at":"2026-10-08T22:59:03Z"}],"visa":[],"liveness":{"score":76,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.803,"p_room":0.945,"age_days":8,"expected_fill_days":21,"reasons":["seen:8","velocity","win:mid"],"computed_at":"2026-10-16T05:45:00Z"},"pay":{"stated_usd_annual":61404,"is_top_pay":false},"html_url":"https://alion.io/job/synerise-scala-engineer","json_url":"https://alion.io/job/synerise-scala-engineer.json","meta":{"generated_at":"2026-10-16T12:55:39Z","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":12245,"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":1683},"rest":"https://alion.io/mcp/rest/get_company?id=1683"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsynerise-scala-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%2Fsynerise-scala-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%2Fsynerise-scala-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/synerise-scala-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsynerise-scala-engineer"}]}
