Postdoctoral Associate ​/ Scientist, Interferometric Signal Processing (Radio Astronomy & Remote Sensing

We’re hiring:
Postdoctoral Associate / Scientist, Interferometric Signal Processing (Radio Astronomy & Remote Sensing)

Location: Montreal, QC — in person
Type: Full-time
Start Date: Fall 2026 (Flexible)
Term: 2 years with possibility of extension into a permanent position

t0.technology builds cutting-edge instrumentation for scientific and industrial sensing, with primary focus areas in superconducting quantum sensors for cosmology and astrophysics, radio correlators, and experimental radar. We are a team of researchers who work closely with academia, government, and industry to develop novel systems at the interface of fundamental physics and engineering.

Our work spans cryogenic detector arrays, large-scale radio-frequency systems, FPGA-based embedded electronics, and custom digital signal processing. We design and deploy real instruments that operate in demanding field environments, while maintaining strong ties to open academic research.

We are seeking a postdoctoral associate with deep expertise in signal processing for radio astronomy to lead work spanning radio array development and deployment, interferometric signal processing, and applied array processing.

The role bridges two tightly linked efforts:

Wideband radio correlators for astrophysics
, including systems deployed for next-generation large-dish-count radio interferometers.

Experimental remote sensing development
, translating radio-astronomy-style correlation, calibration, and array-processing techniques to passive and active imaging in application areas such as space traffic management.

This position spans both real-time signal processing and the analysis pipelines built on top of it, including calibration, map making, and analysis operating close to raw visibilities and time-domain data. Candidates may emphasize algorithm development, system integration, or a hybrid of both.

This role is functionally postdoctoral in nature, with strong expectations for technical leadership, publications, and delivery of working systems. The successful candidate will work closely with internal hardware, firmware, and software teams, as well as external academic and government collaborators. A postdoctoral associate hnology can be a pathway to a staff scientist role with a large fraction of time reserved for self‑directed academic research.

Depending on background and interests, the role may emphasize one or more of the following areas:

A) Interferometric Digital Signal Processing & System‑Level Integration

Design, optimization, and validation of FX‑style correlator pipelines, including channelization, correlation, integration, and statistical characterization.

Design and validation of analog signal chains, antenna arrays, and receiver systems in collaboration with RF and hardware teams.

Development of algorithms that directly inform system architecture, performance limits, and validation of real‑time backends.

B) Algorithmic Inference & Analysis Pipelines

Map making and imaging from interferometric data.

Inverse problems, estimation, and uncertainty quantification in array‑based sensing.

Development of analysis pipelines operating close to raw or lightly processed visibilities and time‑series data.

Simulation, modeling, and validation of algorithms using real instrument data.

Real‑time or near‑real‑time triggered analysis for object or event detection.

Adaptation of interferometric and correlation techniques to sensing, detection, and localization problems.

Algorithmic evaluation of interference mitigation, delay/phase‑lag recovery, and array‑based estimation methods.

This is a research‑focused role within a small, instrument‑driven organization. The position includes a significant allocation of time for independent, self‑directed research, up to 50%.

Independent research topics must be aligned with current or future scientific, technical, or business interests of t0.technology, but are otherwise at the discretion of the researcher. This work may be conducted on‑site or through collaboration with external partners at universities, observatories, or research institutes. We actively support researchers…
