Careers

Build software that brings people home from the river, the border and the sea.

We are a small team building twenty-two products for India's frontiers. The work is technical, often physical, and always checked against a doctrine that says what we will not build. If that suits you, read on.

Open rolescareers@trinetra.in
The work
  • River discharge forecasts that a boat crew can act on before the water rises.
  • Heat guidance that tells a medical officer when a patrol should rest.
  • Sensor fusion that turns radar, thermal and acoustic hits into one honest picture.
  • An audit chain that lets an oversight officer verify what every operator did.

We publish our methods, label simulated data, and say "we do not know" when we do not. We build nothing that profiles or scores people.

Eight roles, October 2026.Full time. Select a role to read it.

Riverine systems engineerKolkata + fieldHardware

Design and field-test Prahari, our riverine sentry pod, so that it survives tides, silt, monsoon floods and salt in the Sundarbans and on the Brahmaputra.

You will

  • Own the pod's power system: solar, batteries, and an energy budget built from measured irradiance.
  • Design floating and stilted mounts, enclosures, and defences against biofouling and corrosion.
  • Integrate radar, thermal and acoustic sensors through Sangam's open schema.
  • Write maintenance routines that a field team can follow from a boat.

You have

  • Four or more years building electronics or power systems that live outdoors.
  • Comfort on boats and in mud, and a habit of writing test plans.
  • Python for analysing field logs.
  • A plus: marine or offshore work, sealed enclosures, Bengali or Assamese.

Edge ML engineerBengaluruMachine learning

Make detection and classification run on small, low-power computers at the river and the post, and report their error rates honestly.

You will

  • Train and compress models for radar, thermal and acoustic data: boats, swimmers, debris and drones.
  • Measure false alarms per hour in field conditions, by place and season.
  • Ship models to ARM devices that may never see a network.
  • Write a model card for every model that ships.

You have

  • Three or more years putting models on edge devices: quantisation, pruning, ONNX or similar.
  • Experience with noisy sensor data from the real world.
  • Respect for evaluation over demos.
  • Note: we do not build face recognition or person identification, and will not ask you to.

Hydrology data scientistBengaluru or remote, IndiaScience

Turn river models and satellite water maps into flood thresholds and crossing windows that people can act on, for Varuna, Nadi, Sarovara and Sandhi.

You will

  • Check modelled discharge (GloFAS) against gauge levels wherever they are public.
  • Set thresholds from climatology and quantify ensemble uncertainty.
  • Track bankline and char change from JRC Global Surface Water, Sentinel-1 and Sentinel-2.
  • Write the methods notes, including the failure modes.

You have

  • A degree in hydrology, water resources or earth science, or equivalent experience.
  • Python with xarray, numpy and pandas; some remote sensing.
  • A clear sense of the difference between a forecast and an observation.
  • A plus: work on the Brahmaputra or Ganga basins, radar imagery.

Full-stack engineerBengaluruSoftware

Build the console and the public site: fast, accessible pages without a framework, fed by Python pipelines that keep working offline.

You will

  • Build console views, public safety pages and data downloads.
  • Write pipelines with caching, retries, manifests and offline rebuilds.
  • Keep every page at zero console errors, clean at 375 px, and usable by keyboard.
  • Wire products into the Sakshi audit chain.

You have

  • Three or more years of web engineering.
  • Strong HTML, CSS and JavaScript without a framework, and working Python.
  • Care for accessibility, performance and small dependency lists.

Sensor fusion engineerBengaluruSoftware

Own Sangam's tracking core and its open SDK, so that integrators can plug any vendor's sensor into one picture.

You will

  • Work on gating, data association, Kalman filtering and track lifecycle.
  • Make the riverine simulator realistic: boats, swimmers, debris, fishing traffic.
  • Publish fusion metrics: track continuity, false tracks, latency.
  • Design the schema and write the SDK documentation.

You have

  • Four or more years in tracking or estimation: radar, sonar, robotics or autonomy.
  • Strong mathematics, Python, and C++ or Rust.
