Staff Software Engineer, Full-stack Order (AI Fluency)

Our requirements

• Real-world experience: 8+ years building software that survives high-traffic production environments, with a track record of leading large-scale projects at the Staff or Principal level.
• Backend mastery: Highly proficient in Golang, ideally also Python or PHP, and able to pick up a new language well enough to ship production code in weeks.
• Distributed systems & API depth: Deep expertise in designing mission-critical, high-throughput REST and gRPC APIs, and the distributed systems under them.
• Cloud & infra mastery: Expert-level AWS and infrastructure-as-code. You understand how your code lives in the wild, and you design for it - not around it.
• Quality & observability: You've designed testing strategies covering Unit, Integration, and E2E automation for distributed environments, and treat observability (tracing, metrics, logging via OpenTelemetry, Prometheus, Grafana) as a first-class feature.
• AI fluency: You've shipped LLMs into production. You understand prompt engineering, fine-tuning, and evaluation of AI outputs. You've built or are building agentic coding systems (autonomous PR reviews, automated refactoring, self-healing test suites) that make entire teams faster.
• Tech debt judgment: You identify, justify, and strategically address tech debt without stalling product momentum. You know which fires to fight and which to let burn.
• Solid fundamentals: Deep grasp of data structures, algorithms, and design patterns - plus the judgment to know when not to over-engineer.
• Strong communication: Solid command of English (min. B2), able to explain complex technical concepts to non-technical stakeholders.

Optional

• The "Figure it Out" gene: You enjoy problems that don't have an answer on the first page of search results - or on any page. You've built the thing no one else on the team knew how to build.
• Full-stack flexibility: Not afraid of React or JavaScript if that's what's needed to get a project across the finish line.
• Mobile backend expertise: Proven experience designing scalable backends for Android apps, with seamless sync and performance under real-world conditions.
• Serverless & event-driven chops: Practical experience with AWS Lambda, Step Functions, or similar event-driven architectures at production scale.
• CI/CD leadership: You've built automated delivery pipelines (GitHub Actions) that teams actually trust.
• Force-multiplier mindset: Engineers who work with you get measurably better - and want to stay.

Your responsibilities

• Set the technical north star: You own the architecture and roadmap behind it. When the system needs to survive 10x growth or a new product bet, you're the one who sees the design through and ships it.
• Become the best in the company, fast: You walk into a new codebase and domain, and within weeks, you're the person others go to for answers.
• Navigate ambiguity others walk away from: We aren't doing simple CRUD work. You'll untangle distributed systems and turn "we have no idea how to do this" into a plan the team can execute.
• Be a "whatever it takes" engineer: Frontend lead out? You jump in. Infra on fire? You look for a solution. An LLM feature stalls? You dig in, ship it, and write the runbook so the team owns it next time.
• Drive the whole org forward: You lead ADRs, high-level code reviews, and mentorship.
• Think product-first: You prioritize end-user journey and business metrics over technical purity. You push back when architecture serves itself instead of the restaurant operators we fight for.
