⚡The Vault by Tria Finance is hiring a Full-Stack Engineer (React + Go/MERN)

About us: We build a security-first platform for digital asset operations. Our product is API-driven, highly auditable, and engineered for reliability. We're looking for a senior full-stack engineer who can own features end-to-end: from clean domain modeling in Go or Node.js to a crisp React UI.

💡What you'll do:
● Build end-to-end product features across Go and Node.js/Express backends and React frontend
● AI-assisted development: use Cursor/Copilot/ClaudeCode (or similar) daily to accelerate delivery, refactoring, and test generation—while verifying outputs and keeping code clean
● Design backend services using DDD patterns (bounded contexts, aggregates, domain events), clean layering, and pragmatic architecture
● Implement data models and migrations across PostgreSQL and MongoDB, using GORM, Mongoose, or raw queries where appropriate
● Build and maintain REST APIs (and webhooks/event-driven workflows where needed) in both Go and Node.js/Express
● Implement frontend flows in React (TypeScript): dashboards, admin workflows, status lifecycles, audit views
● Ensure correctness and observability: structured logging, metrics, tracing, and production-ready error handling
● Contribute to security fundamentals: RBAC, least-privilege access, safe secrets handling, and audit trails
● Own quality: unit/integration tests, contract tests, and CI pipelines

📌Must-have experience:
● 5+ years building production systems with Go and/or the MERN stack (MongoDB, Express, React, Node.js), plus solid React experience
● Strong backend fundamentals: concurrency, APIs, reliability, debugging
● Hands-on with DDD (not just buzzwords): can model domains and keep boundaries clean
● Strong database skills across PostgreSQL and MongoDB: schema/collection design, indexing, query tuning, migrations
● Experience with GORM and/or Mongoose (or similar ORMs/ODMs) plus comfort dropping to raw SQL or aggregation pipelines when needed
● Frontend proficiency in React (TypeScript preferred), including state management and form-heavy admin UIs
● Good testing discipline (Go testing, Jest/Vitest, integration tests; frontend testing basics)

☝️REQUIRED: confident daily use of AI coding tools (Cursor/Copilot/etc.) with disciplined verification and secure practices
Nice to have
● Event-driven patterns: outbox, retries, idempotency, background jobs
● Experience with RBAC/policy engines, audit logs, fintech/compliance workflows
● Docker/Kubernetes familiarity
● CI/CD ownership (GitHub Actions/GitLab CI), release workflows
● Experience with high-security systems (custody, payments, identity)

📌 Work format: remote/hybrid/onsite (Limassol office).

About The Role:
We are looking for a DevOps Engineer to help build, operate, and improve the platform for a security-first crypto custody product: cloud infrastructure, Kubernetes, CI/CD, GitOps delivery, observability, and production operations.
The role involves hands-on work with AWS, Kubernetes, Terraform, GitLab CI/CD, GitOps, observability, and security tooling. We value an engineer who can investigate production infrastructure issues, automate routine work, and improve platform reliability without adding unnecessary complexity.

💡What You'll Do:
● Maintain and evolve AWS infrastructure using Terraform.
● Work with Kubernetes/EKS: deployment, networking, troubleshooting, and resource management.
● Develop GitLab CI pipelines for build, test, security checks, and deployment.
● Support a GitOps delivery model with ArgoCD and Helm.
● Configure and improve monitoring, logging, and alerting.
● Work with secrets, IAM, service accounts, and least-privilege access patterns.
● Participate in incident troubleshooting, root cause analysis, and runbook improvements.
● Help embed security practices into delivery flows: image scanning, dependency scanning, and policy checks.
● Collaborate with backend, frontend, and security teams on infrastructure and delivery topics.

📌Must-have Experience:
● 2-3+ years of experience as a DevOps, SRE, or Platform Engineer.
● Strong Linux knowledge and solid networking basics: DNS, TLS, HTTP.
● Hands-on experience with AWS or another major cloud provider.
● Experience operating Kubernetes in production or close-to-production environments.
● Experience with Terraform or another IaC tool.
● Experience building and maintaining CI/CD pipelines, preferably with GitLab CI.
● Understanding of GitOps; experience with ArgoCD or Flux is a plus.
● Experience with Docker/OCI images, container registries, and Helm charts.
● Basic understanding of observability: metrics, logs, traces, and alerts.
● Understanding of security basics: IAM, secrets management, vulnerability scanning, and least privilege.
● Ability to investigate issues using logs, metrics, and documentation.
● Readiness to document decisions and maintain runbooks/operational docs.

Nice to Have:
● Cilium, Istio, Gateway API, Kyverno.
● External Secrets Operator, IRSA, OIDC to AWS.
● GitLab CI catalog components or reusable pipeline templates.
● OpenTelemetry, VictoriaMetrics/Prometheus, Loki, OpenSearch, Grafana.
● Supply chain security: Cosign, SLSA, SBOM, Trivy, SonarQube.
● Teleport, PAM, VPN-first/private infrastructure access.
● Runtime security tools: Falco, Tetragon.
● Bare-metal, k3s, Ansible.
● Confidential Computing: Intel TDX, AMD SEV-SNP, Kata Containers.
● **Fintech, crypto, regulated, or security-sensitive domain experience.
