Senior Tech Lead FullStack Developer (Java/ ReactJS)

Job description

Mission

Own the technical direction and delivery quality for the product engineering team. As a key member of the team reporting directly to the CEO, you will lead 2 FE and 2 BE developers to ship fast, reliable, and secure features for a multi‑country online pharmacy platform. You combine hands‑on full‑stack depth (Java/TypeScript, modern FE frameworks, APIs, PostgreSQL) with clear leadership, crisp communication, a product mindset, and fluent English to collaborate effectively with technical and business stakeholders. 

Scope & Impact 

• Architecture: Define pragmatic service boundaries, data contracts, and integration patterns across web, ERP, and external partners. 
• Performance: Keep Core Web Vitals in the green on key pages; profile/tune backend APIs and PostgreSQL (p95 latency, error rate, throughput). 
• Delivery: Establish standards for code quality, testing, CI/CD, and release hygiene; drive trunk‑based development with safe feature flags and rollbacks. 
• Reliability: Implement observability (metrics, logs, traces), SLOs/SLIs, incident response, and post‑mortems. 
• Security & Compliance: Enforce secure coding, secrets management, and GDPR‑aware data flows. 
• People: Mentor and grow engineers; run reviews, pairing, and design sessions. 
• Product partnership: Translate business goals into road‑mapped technical work; challenge scope, sequence bets, and balance speed with quality. 

What you’ll lead & do 

• Lead day‑to‑day execution for 2 FE + 2 BE engineers; sprints and technical quality. 
• Hands‑on development (~50% IC time): design and implement core features end‑to‑end across backend (Java/Spring Boot, Kafka/RabbitMQ, PostgreSQL, Redis) and frontend (React 18+/TypeScript). 
• APIs and integrations (auth, contracts, versioning, idempotency, retries. 
• Guide front‑end architecture in React 18+/TypeScrip, shared components, accessibility, and performance. 
• Drive backend quality using Java (Spring Boot) and/or Python where appropriate; model data, tune queries, and optimize PostgreSQL. 
• Improve build pipelines (Vite/Webpack on FE, CI/CD on BE); automate tests and deployments; codify templates and scaffolds. 
• Create technical docs, runbooks, and standards to make the team faster and safer. 
• Vendor & RFP support: Provide technical input during vendor selection and RFP drafting; define criteria (platform choices, deployment strategy, KPIs, analytics); support vendor interviews and architecture evaluations. 

Key projects & administrative duties 

• Projects: Drive development of custom ERP, CMS, and supporting platform systems for a large e‑commerce environment. 
• Plan & deliver: Implement work according to the assigned plan; ensure delivery on schedule and at the required quality bar. 
• Team: management, training, and guidance of project staff. 
• R&D: Research and develop new technologies aligned to the roadmap. 
• Project participation: Participate in and complete assigned projects as required. 
• Governance: Implement planning and reporting regime according to regulations.

Your skills and experience

• Leadership & delivery: Led 4–8 engineers end-to-end (planning, reviews, feedback, hiring); shipped outcomes in a product org (not agency/outsourcing). 
• Hands-on full-stack: Recent (last 12 months) production code across Java/Spring Boot and React 18+/TypeScript; able to code ~50% when needed. 
• System design (pragmatic): Service boundaries, data contracts, caching, and failure modes; microservices when justified (buy-vs-build judgment). 
• Data: Strong PostgreSQL (indexes, plans, partitions, migrations) and depth in one non-relational store (Elasticsearch or MongoDB). 
• Messaging: Proficiency with Kafka or RabbitMQ (retries, idempotency, DLQs). 
• Platform & cloud: Docker plus Kubernetes (preferred) or managed orchestration on AWS/GCP; CI/CD literacy. 
• APIs & contracts: REST + one typed contract (gRPC with Protobuf or Avro with schema registry); versioning and compatibility. 
• Security & compliance: OAuth2/OIDC, secrets management, PII/GDPR by design. 
• Communication: Excellent written/spoken English; crisp stakeholder updates; can write docs/runbooks. 

Nice-to-have: WSO2 or Kong; Redis; event sourcing/multi-tenant; observability stack; e-commerce/search; Odoo/Symfony/PHP.
