Engineers hired at the Staff level additionally carry cross-team technical leadership — shaping architecture, raising the engineering bar, and driving multi-quarter initiatives. This role directly impacts the company by ensuring the accuracy, security, and scalability of the systems that collect and account for customer revenue.\n\nResponsibilities\nThis position includes the following duties. Other duties may be assigned to meet business needs. \nDesign event-driven, event-sourced microservices for a multi-tenant SaaS platform — from domain modeling through API contracts (GraphQL, including federated schemas, and REST) and data schemas.\nBuild high-throughput, low-latency transaction-processing services in a modern strongly typed language (e.g., Rust, Go, Kotlin/Java).\nImplement event sourcing and CQRS patterns over an event-streaming backbone (e.g., NATS, Kafka) with strong delivery and idempotency guarantees.\nHandle money correctly by construction: typed monetary amounts, auditable ledgers, idempotent effects, and defensive integration with third-party payment providers.\nContribute to TypeScript front ends built with a modern component framework (e.g., Svelte/SvelteKit, React/Next.js), including backend-for-frontend patterns, shared packages, and generated client SDKs in a monorepo.\nWrite thorough unit, integration, and end-to-end tests, including parallel test suites that surface concurrency defects.\nApply secure-by-design practices: least-privilege access, tenant isolation (e.g., row-level security), policy-as-code authorization (e.g., OPA), and centralized secrets management — within payment-industry (PCI DSS) and audit (e.g., SOC 2) requirements.\nOwn services in production: instrument with metrics, logs, and traces (e.g., OpenTelemetry, Prometheus, Grafana); lead root-cause analysis.\nDeploy to Kubernetes via Helm and code-first CI/CD pipelines; keep services healthy through capacity planning and performance tuning.\n\nAuthor and review design documents and RFCs; conduct architecture and peer code reviews to critique and improve engineering design.\n\nLead, mentor, advise, and assist in the training of junior engineers; at the Staff level, drive cross-team technical initiatives and align architecture across services.\n\nQualifications\n\nRequired Skills/Abilities: Must be self-motivated and a strong individual contributor, able to own ambiguous, multi-service problems end to end and deliver incrementally.\nStrong written and oral communication skills — design documents, RFCs, and reviews that other engineers can build on.\nCommunicate clearly and concisely with all levels of leadership, both internal and external (customer), to lead meetings and presentations.\nInterface with and support customers, executive staff, product management, project management, QA, and operations teams.\nExhibit a fundamental understanding of all aspects of a tolling platform from roadside to back office — including operations, integrations, and the rigor (idempotency, auditability, failure-mode analysis) demanded of systems that move money.\nEducation and Experience: BS in Computer Science, Software Engineering, or equivalent work experience.\nSenior level: 5+ years of professional software engineering experience. Staff level: 8+ years, including a demonstrated track record of technical leadership across teams.\nExperience designing, building, and operating distributed backend systems in production — ideally event-driven and/or high-volume transaction processing — with a modern strongly typed language (e.g., Rust, Go, Kotlin, C#) and TypeScript.\nHands-on experience with cloud platforms (AWS, Azure, or Google Cloud) and containerized deployment on Kubernetes (Helm; code-first CI/CD pipelines such as Dagger or GitHub Actions).\nExperience with relational and distributed SQL databases (e.g., PostgreSQL, YugabyteDB, CockroachDB); event-streaming systems (e.g., NATS, Kafka) preferred.\nExperience in payments, financial systems, tolling, or intelligent transportation systems strongly preferred.\nProficiency working in Linux environments.\n\nBenefits\nWe offera Total Rewards plan designed with you and your family’s health and wellness in mind that includes:\n\nPaid days off (i.e.vacation, sick days, bereavement leave)\n\nHealth and Dental plans\n\nRetirement plans\n\nEmployee and Family Assistance Program (EFAP)\n\nEmployee referral program\n\nEmployee Stock Purchase Program (ESPP)\n\nExternal Salary Range: 150K - 190K annually.\nInternal Salary Range: To be determined.\nWe welcome applicants from all backgrounds, regardless of race, color, religion, sex, veteran status, sexual orientation, gender identity, national origin, age, or disabilityor any other protected characteristics in accordance with applicable federal, state/provincial, and local laws. We're committed to creating a workplace where everyone feels valued and respected. \nWe appreciate all responses and will acknowledge only those being considered for an interview.We respectfully request no calls or unsolicited resumes from Agencies.\nOriginally posted on Himalayas","description_format":"text","description_chars":5570,"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":["Retirement plans"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Automotive Software","Supply Chain & Logistics Software"],"lifecycle":[{"event":"open","at":"2026-11-08T17:28:55Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":47,"reasons":["seen:0","win:early"],"computed_at":"2026-11-09T06:03:00Z"},"pay":{"stated_usd_annual":190000,"is_top_pay":false},"html_url":"https://alion.io/job/quarter-hill-seniorstaff-software-engineer","json_url":"https://alion.io/job/quarter-hill-seniorstaff-software-engineer.json","meta":{"generated_at":"2026-11-09T14:47:54Z","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":20499,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1986947},"rest":"https://alion.io/mcp/rest/get_company?id=1986947"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fquarter-hill-seniorstaff-software-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fquarter-hill-seniorstaff-software-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fquarter-hill-seniorstaff-software-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/quarter-hill-seniorstaff-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fquarter-hill-seniorstaff-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3943639}},{"tool":"search_jobs","arguments":{"company":"quarterhill.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3943639},"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.
