Senior Software Engineer

Cue is a modern customer service chat software company. Our Live Chat, Chatbot and Broadcast products help businesses to provide customer support at scale across WhatsApp, Messenger, Web chat, email and Telegram. We are growing rapidly and are now expanding into the international market on our journey to become an international market leader. We're looking for deeply experienced engineers to join our team in a role that's genuinely new: designing and architecting backend systems, then directing AI agents to build them, and critically verifying the results. This isn't a traditional coding role. You'll spend your time understanding problems, designing solutions, writing specs, and working with AI tooling to bring those solutions to life — fast. The catch: you need the hard-won experience to know when the AI gets it wrong. That means you've built and operated real systems, dealt with real failures, and developed the instinct for what "right" looks like. What you'll do Architect backend services and distributed systems from first principlesWrite clear design specs and technical proposalsUse AI agents and tooling to accelerate implementationReview and verify AI-generated code and architecture with a critical eyeOwn systems end-to-end: from problem definition through production operationCollaborate with the team to evolve our engineering practices as AI tooling matures What you bring Significant experience designing and operating microservices architectures in productionStrong Linux, networking, and infrastructure fundamentals (SRE/platform background ideal)Hands-on experience with containers, Kubernetes, CI/CD, and observabilityFluency reading and writing code — you don't need to be the fastest coder, but you need to understand code deeplyActive use of AI coding tools and LLM-based workflowsThe confidence and experience to challenge AI output when it doesn't meet the barA track record of owning projects from conception through productionA collaborative working style — you enjoy designing in the open, sharing early ideas, and building on other people's thinkingGenuine curiosity — you explore problems because you want to understand them, not just close tickets Our stack You don't need to have used all of this, but this is the world you'll be working in — and the closer your experience, the better your instincts will serve you: Infrastructure: AWS (multi-account), Terraform + Terragrunt, Atlantis for automated deploymentCompute: EKS with Karpenter autoscaling, ECS Fargate, LambdaMessaging & streaming: Kafka (MSK), SQS (standard + FIFO) with dead letter queuesData: Aurora Serverless v2 (PostgreSQL), Elasticsearch, Redis (ElastiCache), InfluxDBNetworking: Traefik ingress with NLBs, ExternalDNS, cert-manager, Route53, CloudFront, VPC peeringSecurity: GuardDuty, Security Hub, Elasticsearch SIEM, CrowdSec WAF, Firezone (Zero Trust)Observability: Grafana, CloudWatch, Fluent Bit, GoldilocksCI/CD: ArgoCD, GitHub Actions (OIDC), Atlantis What we value over credentials We don't care about your degree, which languages you've used, or whether you can invert a binary tree on a whiteboard. We care that you've built things that worked, fixed things that broke, and learned from both. This role is a great fit if you... Have been the person responsible when production breaks at 3amHave strong opinions about system design, backed by experienceAre excited about AI as a tool, but not naive about its limitationsWant to spend more time thinking and designing, and less time in an IDETake ownership instinctively — you don't wait to be toldHave war stories from production Kubernetes — OOMKills, node scaling failures, networking mysteriesKnow what it feels like when a Kafka consumer falls behind or a dead letter queue starts filling upHave stared at a database failover and understood why connections didn't recoverHave debugged a problem that started at the load balancer and ended at a misconfigured secret three layers deepUnderstand that the interesting failures always cross boundaries between systemsBelieve the best architecture comes from discussion, not isolationEnjoy pairing, whiteboarding, and poking holes in each other's designs — and having yours poked at in returnGet energy from working with good people, not just from solving hard problems alone How we work We're a small team with high standards. Every engineer here carries real ownership — there's no hiding behind process, and no waiting for someone else to pick something up. We don't work long hours, but we work hard ones. When you're on, you're focused, making decisions, and shipping. We expect you to unblock yourself, ask for help when it's genuinely needed, and take responsibility for outcomes. We design together, review each other's work honestly, and assume good intent. If you're the type of engineer who thrives when surrounded by peers who challenge and support you in equal measure — and who does their best work when trusted with real responsibility — you'll fit right in. This isn't for everyone, and that's fine. If you want well-defined swim lanes and a ticket queue, we're not the right team. If you want ownership, pace, and the satisfaction of seeing your decisions running in production — we are.
