Role: Algorithm Developer
Location: BANGALORE
Experience: 3-8 Years
Employment Type: Full time
Notice Period:0-30 days(If you have negotiable notice period or buyout option please apply)
Requirements
Job Opening: Algorithm Developer / Engineer
Domain: Aerospace and
defence, multi-sensor data fusion
Openings
Profile | Openings | Experience |
Algorithm Developer,
MATLAB | 4 | 3 or more years |
Algorithm Developer,
Python | 4 | 3 or more years |
Lead Algorithm Engineer | 1 | 5 to 6 years |
Candidates strong in both MATLAB
and Python are preferred for every profile.
Common details
• Location: Bangalore, full-time at the client
site. Remote or hybrid work is not possible.
• Work environment: Closed network with no
internet access. You must derive equations and write code from your own
knowledge.
• Before joining: Police verification and
background check are mandatory.
Role summary
Design, develop and validate
data fusion, tracking and recognition algorithms. Prototype them in MATLAB or
Python, measure their performance, and hand the benchmarked algorithms to the
software team for embedded implementation.
Key responsibilities
• Convert mathematical equations and algorithm
descriptions into working code.
• Design and implement fusion, tracking or recognition
algorithms.
• Build sensor models from interface specifications.
• Build simulations and generate test data to check the
algorithms.
• Measure performance with numbers: accuracy, track
continuity, false track rate and latency.
• Benchmark candidate algorithms and recommend the best
performer.
• Define test cases and carry out standalone algorithm
testing.
• Write clear, commented code and document the equations,
design and results.
• Present designs at formal design reviews and close the
action points raised.
• Support the software team when the algorithm is
converted to C/C++.
Qualification
• B.E./B.Tech in ECE, EEE, CSE or Aerospace, or M.Sc in
Mathematics or Physics. M.E./M.Tech is preferred.
• Minimum 3 years of hands-on algorithm development in
MATLAB or Python.
