Senior Backend Engineer at Zan - Zari Group · Remote only · 4 - 10 years · ₹7L - ₹10L / yr · Bootstrapped · Remote only · Posted 17 Sep 2026

This is a backend role. You won't build screens, and you don't need frontend experience. The mobile team will add a language picker and pass a locale to the backend. Everything behind that is yours: the data model, content pipelines, LLM generation, retrieval, audio, notifications, and making sure all of it holds up in production.
What you'll build
1. The language data model
- Design how language lives in the database: user language preference, per-story translations, fallback chains (e.g. pt-BR → pt → en), and versioning so a translation is marked stale when its English source changes.
- stories.translations (jsonb) already exists and nothing reads it yet. Decide whether it stays, or whether we move to a dedicated story_translations table, and write down why.
- Everything ships as new, reversible migrations. We never edit an existing migration.
2. The content translation pipeline
- Our library has already been translated into several languages using the Anthropic Batch API, with a two-pass generate-then-review process. Move this into the repo so it's idempotent, re-runnable and cheap, and so it handles only the stories that changed.
- Build a glossary and style layer: Hebrew terms, names of sages and sources, and terms that must never be translated. Add automated QA checks (completeness, glossary adherence, length drift, broken formatting) plus a sampling workflow for native-speaker review.
3. Generation in the user's language
- Reflections, bridge text, the three practices (Echo, Naming, Walking) and Path arcs are generated by Claude through shared prompt modules in our Supabase edge functions. Make them produce native, natural output in the target language. That means writing in the language directly, not translating English after the fact. Our existing rules must still hold, e.g. each practice carries a Hebrew term with its meaning explained, now explained in the user's language.
- Build a per-language evaluation harness so we can check quality before a language goes live and catch regressions when prompts change.
4. Multilingual matching
- Today, language-validation detects the language of the user's input and blocks anything that isn't English. Replace that gate with detection and routing.
- Story matching uses OpenAI text-embedding-3-large over pgvector. Measure how well non-English input retrieves the right English-indexed stories. Then decide between cross-lingual matching, per-language embeddings, or a hybrid, and back the decision with numbers.
5. Audio
- Stories and reflections are read aloud by ElevenLabs voices. Audio is currently stored per voice (audio_urls), so it has to become per voice and per language. Pick voices for each language, and plan batch pre-rendering, storage, cost and backfill.
6. Server-side copy
- Move push notification copy (including our Shabbat-aware scheduling), transactional and lifecycle emails, and database-driven home-screen messages out of the code and into a locale-aware string system with proper plurals and date formats.
7. Safe rollout
- Several app versions are live at the same time, and older builds can't be changed. Every change you make must stay backward compatible: English stays the default, current RPC signatures stay the same, and each language can be switched on independently behind a flag.
- Track cost and quality for each language: tokens, TTS credits, fallback rate and generation failures.
Our stack
- Backend: Supabase: Postgres (RLS, RPCs, pgvector, jsonb, pg_cron) and 50+ Deno/TypeScript edge functions
- AI: Anthropic Claude (Messages and Batch APIs, prompt caching), OpenAI embeddings, ElevenLabs TTS
- Data/scripts: Python and Node
- Other: RevenueCat, Resend, Expo Push/FCM. The app is Expo/React Native, but you won't need to work in it.
You'll be a fit if you have
- 5+ years of backend engineering, with strong PostgreSQL: schema design, migrations on live data, RLS, stored functions, and performance tuning.
- Production TypeScript (Deno or Node) and solid Python for data pipelines.
- Shipped LLM features to production, beyond prototypes: prompt design, structured output, batch processing, cost control, and above all evaluation. You know how to tell whether output in a language you don't speak is good.
- Built backend internationalization before: locale negotiation, fallback chains, ICU/CLDR plurals and dates, and translation workflows with versioning.
- Worked with embeddings and vector search, and can design a retrieval evaluation.
- Care about keeping production running: backward compatibility, feature flags, and rollouts that can be undone.
- Write clearly. Decisions here get written down before they get built.
Nice to have
- Experience with ElevenLabs or other TTS pipelines.
- Supabase-specific experience.

About Sentiaflow
Sentiaflow is an AI engineering and IT services company building production-grade agentic AI systems, sitting at the intersection of LLMs and real business operations — data, APIs, permissions, workflow state, human decisions, security, and measurable outcomes. Our initial domain focus is healthcare, particularly clinical trials, where reliability, traceability, and clear human-decision boundaries matter more than a slick demo.
Job Description
As a Level 1 engineer, you'll implement bounded parts of a production agentic workflow under an Agent Captain or senior engineer, connecting models to application services, tools, data sources, and human approval points.
You will:
- Translate a scoped business workflow into typed inputs, outputs, states, actions, and escalation paths
- Build backend services and tool integrations (Node.js/TypeScript or Python)
- Use LLMs only where model judgment adds value; keep rules, validation, authorization, and workflow control in deterministic code
- Design and validate structured model outputs before they touch downstream systems
- Handle partial data, tool failures, duplicate events, retries, timeouts, rate limits
- Add logging, traces, metrics, and decision records for diagnosability
- Write tests and evaluation cases that check whether the full workflow behaves correctly — not just whether output sounds fluent
- Protect sensitive data; participate in code, design, and release-readiness reviews
- Explain implementation trade-offs clearly to engineers and stakeholders
Success in 6 months: own a bounded workflow module end-to-end, integrate models without letting probabilistic output bypass deterministic controls, produce release-ready evaluation evidence, and diagnose cross-boundary failures with less supervision.
Desired Skills
- Approximately 3–6 years hands-on backend/application engineering experience, with demonstrable hands-on work building agentic systems — not just calling an LLM API from a backend service
- LangGraph (or comparable agent orchestration framework) experience is required — building multi-step, stateful agent workflows with conditional branching, tool-calling loops, and recovery/retry logic, not a single-prompt wrapper
- Deep RAG experience, including:
- Chunking strategy design, embedding model selection, and retrieval evaluation (not just "connected a vector DB")
- Hybrid search (dense + sparse/keyword), re-ranking, and query rewriting/decomposition
- Handling retrieval failure modes: irrelevant context, stale data, contradictory sources, citation/grounding accuracy
- Measuring RAG quality (precision/recall on retrieval, faithfulness/groundedness of generation) — not eyeballing outputs
- Experience designing agent state machines / workflow graphs: tool selection, planning loops, human-in-the-loop interrupts, checkpointing, and state persistence across long-running workflows
- Strong programming in JS/TypeScript (preferred), Python, Java, C#, or Go
- Solid grasp of API design, databases, async processing, auth, testing, deployment
- Comfort reasoning about state, retries, idempotency, concurrency, permissions, audit trails, failure recovery
- Real production debugging experience, not just greenfield builds
- Clear technical communication
We're looking for engineers who've actually built and tuned agentic/RAG systems in production — not those who've only wired together frameworks or prompted an LLM API.
Nice to have: experience with other orchestration frameworks (CrewAI, AutoGen, custom state machines), observability/eval tooling (LangSmith, Langfuse, custom trace pipelines), healthcare or regulated-industry background. Bachelors from IIT or NIT highly preferred.
We’re building financial data systems that power real business decisions — and we need someone who knows how to make Django, PostgreSQL, Celery, and APIs play nicely at scale.
You know what clean, reliable backend systems look like — because you’ve built them. You’ve handled authentication quirks, rate limits, and webhooks; you build code that’s maintainable, performant, and correct.
If you’re curious about financial data, transactions, and KPIs, and enjoy turning numbers into insight, this role is for you. (Experience with banking or accounting APIs is a big plus.)
What You’ll Do
- Build and maintain Django-based systems using Celery for async and scheduled tasks
- Integrate and manage data from multiple APIs (banking, accounting, analytics, etc.)
- Design and optimize internal APIs
- Improve reliability, scalability, and performance
- Collaborate closely with product and frontend engineers
Your Profile
You’re an experienced backend engineer who is strong in all core areas of modern Python development:
- Python, Django, Django REST Framework
- Celery and asynchronous / distributed task handling
- PostgreSQL and robust data modeling
- Docker and containerized deployment workflows
- Unit testing (pytest or equivalent) and maintainable test structures
- Git, CI/CD, and reliable deployment automation
- API integrations (REST, OAuth, webhooks)
- Caching strategies & background job handling (preferred Redis experience)
- Solid understanding of security, permissions, and performance optimization
You’ve already built or scaled production-grade systems and can take ownership from architecture to deployment.
Experience with fintech or data integration systems is an advantage.
How We Work
We’re a small, remote-first team that values ownership over micromanagement.
You’ll have freedom in how you work — what matters is your impact.
Our daily language is English.
About finban
We’re building a platform that helps businesses understand and manage their financial performance in real time by connecting and analyzing data from banking, accounting, and analytics systems.
If you’ve built or scaled production Django systems before and love clean architecture — we’d love to see your work.
