Team MissionOmnichannel Integrations Team connects Text to the messaging platforms customers actually use to talk to businesses — Messenger, WhatsApp, Instagram, Telegram, Twilio, and more.We build native, first-class integrations inside Text: consistent conversation history, reliable message delivery, correct attachment handling, and predictable behavior across channels — even when each platform has its own quirks.We’re at an inflection point: we’re moving from externally-built connectors to building and owning key channels in-house, which means you’ll help set foundations and standards — not just maintain what exists.About the RoleWe’re looking for a Senior Backend Engineer (Go) to design, build, and scale the backend foundations for Omnichannel integrations at Text.In practice, you’ll build systems that translate third-party messaging platforms into a consistent internal model, keep data flowing reliably into the Inbox, and stay correct under real-world constraints.This is reliability-heavy integration work, not “API wiring.” External APIs evolve, webhooks can be flaky, and constraints like rate limits, ordering, retries, idempotency, and media limits are part of the job — and customers notice immediately when conversation breaks.High ownership: you’ll be joining early on the backend side of the team, with strong influence on architecture, patterns, and scaling strategy.What you’ll doBuild backend services for Omnichannel integrations and scale coverage across channels.Design ingestion and sync flows that are resilient by default (deduplication, retries, idempotency, ordering guarantees).Translate third-party concepts into Text’s internal domain model (messages, threads, participants, attachments, metadata).Handle channel-specific constraints without breaking user experience (media size limits, API versioning, delivery semantics).Improve operational reliability with strong observability (metrics, logs, tracing, alerting) and debuggable failure modes.Collaborate closely with teams across Text to keep data flows consistent and trustworthy.Shape architecture decisions: what becomes a reusable platform layer vs. channel-specific logic.Who you areOwnership mindset: you treat the systems you own as products — and care about production outcomes.Systems thinking: you reason in failure modes, trade-offs, and long-term maintainability.Integration pragmatism: you can navigate messy external APIs and still build clean abstractions.Reliability-first: you design for partial failure (timeouts, duplicates, out-of-order events) and predictable behavior.Clear communication: you keep alignment and visibility as part of execution.You may be a great fit if you have6+ years of backend engineering experience in product-focused environments.Strong production experience with Go (Golang).Solid distributed systems fundamentals (consistency trade-offs, retries/idempotency, backpressure, event-driven patterns).Experience integrating with third-party platforms and operating services in production.Comfort with SQL (PostgreSQL) plus stores like Redis.Experience with Pub/Sub or Kafka and async/event-driven architectures.Familiarity with cloud infrastructure (GCP preferred) and modern delivery/ops practices (CI/CD + observability).Nice to haveExperience with messaging/social channels (Meta APIs, WhatsApp Business, Instagram, Telegram, Twilio, or other providers).Experience in integration-heavy products where external change is frequent (versioning, deprecations, migrations).Experience designing media/attachment handling at scale (limits, retention/lifecycle, storage costs, delivery reliability).Exposure to enterprise SaaS constraints (security/compliance mindset).Why you’ll love working with usInflection-point ownership: you’ll shape foundations, patterns, and standards for Omnichannel.High-impact channels: work on integrations customers care about most — high usage and business impact.Real engineering challenges: reliability and correctness under external constraints.Strong platform foundations: security/compliance/reliability baseline exists, so you can focus on evolution.Cross-product impact: your work powers Inbox experience and downstream features relying on trustworthy conversation data.⚡️ If you enjoy integration-heavy backend work, distributed-systems challenges, and building systems customers rely on daily — we’d love to meet you.The way we workWe’re a hybrid team – remote when it makes sense, onsite when it matters most.Once per quarter, your whole team spends 5 working days together at our Wrocław office – a time for focused execution, unblocking work, and driving key outcomes.Our office is open year-round – drop by anytime.Contract: B2B (self-employed). You’ll need a registered business in selected EU countries — either already set up or possible to register in your country. Please apply only if this works for you.
